-ChangeLog
-  v0.15
-    *   now more_set_headers supports overriding charset in Content-Type.
-        thanks ML.
-
-    *   fixed an issue in more_clear_headers: we should remove all the
-        instances of the headers specified, not only the first occurrence.
-        thanks Li Yang.
-
-    *   back-ported a bugfix from ngx_lua: in output header set, we should
-        always set the header->hash to 1. thanks moodydeath for reporting
-        it.
-
-    *   fixed a bug when clearing the Accept-Ranges header. thanks Bo
-        Blangstrup.
-
-  v0.14
-    *   now we postpone the rewrite phase handler only once rather than on
-        every main request previously. this will save some CPU cycles on
-        every request if more_set_input_headers or more_clear_input_headers
-        are used.
-
-    *   fixed two spots where we did not check against null pointers when
-        out of memory.
-
-    *   now we use the 2-clause bsd license instead.
+Changes
+    The changes of every release of this module can be obtained from the
+    ngx_openresty bundle's change logs:
 
-    *   various coding style fixes.
-
-  v0.13
-    *   fixed a bug in rewrite phase postponing algorithm which may cause
-        ngx_eval (<http://www.grid.net.ru/nginx/eval.en.html>)'s eval block
-        running *after* ngx_rewrite
-        (<http://wiki.nginx.org/HttpRewriteModule>)'s directives. thanks
-        Liseen Wan (xunxin).
-
-  v0.12
-    *   fixed a bug in the Content-Type output header setting handler. we
-        should always clear "r->headers_out.content_type_lowcase", or it'll
-        confuse output filters like that of the gzip module.
-
-  v0.11
-    *   fixed the variables-in-Range-header issue in more_set_input_headers
-        reported by Alexander Vetrin.
-
-  v0.10
-    *   now we can remove an input and output header *completely*, including
-        both custom and builtin headers.
-
-  v0.09
-    *   fixed a memory initialization issue for more_set_input_headers
-        without the "-r" option, we should always initialize "hv.replace"
-        even when replace == 0. This may result in server segfaults and was
-        introduced in v0.08.
-
-    *   implemented wildcard support in more_clear_headers. Thanks Bernd
-        Dorn.
-
-  v0.08
-    *   applied the patch from Bernd Dorn to add the "-r" option to the
-        more_set_input_headers directive.
-
-  v0.07
-    *   fixed the more_clear_headers directive for builtin headers like
-        "Server" and "Last-Modified" by always inserting an empty header
-        when absent. Thanks Sebastiaan Deckers for reporting it.
-
-  v0.06
-    *   now the input header handler runs at the *end* of the "rewrite
-        phase" such that it works in subrequests by default.
-
-  v0.05
-    *   fixed variables in more_set_input_headers by registering the handler
-        in the "access phase" instead of the "rewrite" phase.

-
-== v0.15 ==
-* now more_set_headers supports overriding charset in Content-Type. thanks ML.
-* fixed an issue in more_clear_headers: we should remove all the instances of the headers specified, not only the first occurrence. thanks Li Yang.
-* back-ported a bugfix from ngx_lua: in output header set, we should always set the header->hash to 1. thanks moodydeath for reporting it.
-* fixed a bug when clearing the Accept-Ranges header. thanks Bo Blangstrup.
+== Chinese Mailing List ==
 
-== v0.14 ==
-* now we postpone the rewrite phase handler only once rather than on every main request previously. this will save some CPU cycles on every request if [[#more_set_input_headers|more_set_input_headers]] or [[#more_clear_input_headers|more_clear_input_headers]] are used.
-* fixed two spots where we did not check against null pointers when out of memory.
-* now we use the 2-clause bsd license instead.
-* various coding style fixes.
+The [https://groups.google.com/group/openresty openresty] mailing list is for Chinese speakers.
 
-== v0.13 ==
-* fixed a bug in rewrite phase postponing algorithm which may cause [http://www.grid.net.ru/nginx/eval.en.html ngx_eval]'s eval block running ''after'' [http://wiki.nginx.org/HttpRewriteModule ngx_rewrite]'s directives. thanks Liseen Wan (xunxin).
+= Bugs and Patches =
 
-== v0.12 ==
-* fixed a bug in the Content-Type output header setting handler. we should always clear <code>r->headers_out.content_type_lowcase</code>, or it'll confuse output filters like that of the gzip module.
+Please submit bug reports, wishlists, or patches by
 
-== v0.11 ==
-* fixed the variables-in-Range-header issue in [[#more_set_input_headers|more_set_input_headers]] reported by Alexander Vetrin.
+# creating a ticket on the [http://github.com/chaoslawful/lua-nginx-module/issues GitHub Issue Tracker],
+# or posting to the [[#Community|OpenResty community]].
 
-== v0.10 ==
-* now we can remove an input and output header ''completely'', including both custom and builtin headers.
-
-== v0.09 ==
-* fixed a memory initialization issue for [[#more_set_input_headers|more_set_input_headers]] without the <code>-r</code> option, we should always initialize <code>hv.replace</code> even when replace == 0. This may result in server segfaults and was introduced in [[#v0.08|v0.08]].
-* implemented wildcard support in [[#more_clear_headers|more_clear_headers]]. Thanks Bernd Dorn.
+= Source Repository =
 
-== v0.08 ==
-* applied the patch from Bernd Dorn to add the <code>-r</code> option to the [[#more_set_input_headers|more_set_input_headers]] directive.
+Available on github at [http://github.com/agentzh/headers-more-nginx-module agentzh/headers-more-nginx-module].
 
-== v0.07 ==
-* fixed the [[#more_clear_headers|more_clear_headers]] directive for builtin headers like <code>Server</code> and <code>Last-Modified</code> by always inserting an empty header when absent. Thanks Sebastiaan Deckers for reporting it.
+= Changes =
 
-== v0.06 ==
-* now the input header handler runs at the ''end'' of the <code>rewrite phase</code> such that it works in subrequests by default.
+The changes of every release of this module can be obtained from the ngx_openresty bundle's change logs:
 
-== v0.05 ==
-* fixed variables in [[#more_set_input_headers|more_set_input_headers]] by registering the handler in the <code>access phase</code> instead of the <code>rewrite</code> phase.

-    <h3>How to extract generated rules from the database : </h3>
-    <ul>
-      <li>
-	A GET request on /get_rules will display the generated rules. Non-optimised rules will be displayed in comment.
-      </li>
-    </ul>
-    <h3>The available args on /get_rules are : </h3>
-    <ul>
-      <li>
-	<p>
-	<b>rules_file</b> : Path to the core rules file of naxsi (typically /etc/nginx/conf/naxsi_core.rules).<br />
-	This arg is used to display the message associated with the rule (ie, will display "double quote" if the rule 1001 is whitelisted).<br />
-	If this arg is not present, an error message will be displayed.	
-	</p>
-      </li>
-      <li>
-	<p>
-	<b>page_hit</b> :  Minimum number of pages triggering the same event before proposing the optimisation (ie, if there is more than 10 urls that trigger a rule, the rule will be whitelisted on every url).<br />
-	Default to 10.
-	</p>
-      </li>
-      <li>
-	<p>
-	  <b>rules_hit</b> : Minimum number of rules hitting the same event on the same page before proposing optimisation (ie, if there is more than 10 differents rules triggered on the same url, all rules will be whitelisted on that url)<br />
-	  Default to 10.
-	</p>
-      </li>
-    </ul>
-    <h3>Example : </h3>
-<ul>
-<li>
-      Optimise the rules if more than 7 exceptions on the same arg are triggered on a page (whitelist all rules on the arg on this page) : 
-    <a href="http://__HOSTNAME__/get_rules?rules_hit=7">http://__HOSTNAME__/get_rules?rules_hit=7</a><br />
-</li>
-<li>
-      Optimise the rules if more than 7 exceptions on the same arg are triggered on a page (whitelist all rules on the arg on this page) or if more than 10 pages trigger the same rule (whitelist the rule on every page): 
-    <a href="http://__HOSTNAME__/get_rules?rules_hit=7&page_hit=10">http://__HOSTNAME__/get_rules?rules_hit=7&page_hit=10</a><br />

-PAM Environment
----------------
-
-The plugin set's the following additional environment variables when using ``pam_exec.so``
-as pam module for authentication:
-
-	REQUEST=GET /some/url?foo&bar HTTP/1.1
-	HOST=localhost:8000

-You may use this information for request based authentication.
-You need a recent pam release (>= version 1.0.90) to expose environment
-variables to pam_exec (Ubuntu 8.04 has a too old pam version here!).

-Features that sooner or later will be added to `ngx_cache_purge`:
-
-* Add support for alternative in-location cache purges using specified
-  request method, with following configuration syntax:
-
-      location / {
-          proxy_pass         http://127.0.0.1:8000;

-
-  This will allow for purges using:
-
-      curl -X DELETE http://example.com/logo.jpg
-
-  instead of:
-
-      curl http://example.com/purge/logo.jpg
-

 Features that __will not__ be added to `ngx_cache_purge`:
 
 * Support for prefixed purges (`/purge/images/*`).

-ChangeLog
-  v0.36
-    *   now we back-ported the subrequest mechanism of ngx_lua to ngx_echo.
-        this also helps some crazy test cases of mixing echo_location and
-        echo_location_async pass now.
-
-    *   now echo_location and its friends can work with ngx_xss (as well as
-        other output filter modules) completely. thanks wd for reporting
-        this issue.
-
-    *   done some minor optimization when modifying subrequest's
-        content-length header.
-
-    *   now we always pad a trailing \0 to filepath in
-        "echo_subrequest(_async) METHOD /path -f filepath" because
-        ngx_open_cached_file requires a C string file name. thanks dr-dr xp.
-
-    *   made our filter optimization works with nginx HUP by clearing the
-        ngx_http_echo_filter_used flag at nginx pre-config callback. thanks
-        Marcus Clyne.
-
-  v0.35
-    *   added the "-f /path/to/file" option to the echo_subrequest and
-        echo_subrequest_async directives to allow POST/PUT a disk file in
-        the subrequest. thanks Bernd Dorn (<https://github.com/dobe >).
-
-  v0.34
-    *   we no longer use the problematic "ngx_strXcmp" macros in our source
-        because it may cause invalid reads and thus segmentation faults.
-        thanks Piotr Sikora.
-
-  v0.33
-    *   fixed compatibility with nginx 0.7.66+ because the ngx_time_update
-        macro's parameter list has changed. thanks Guang Feng (蔡镜明).
-
-  v0.32
-    *   we should have used "ngx_calloc_buf" instead of "ngx_alloc_buf" for
-        the last chunk generated for echo_after_body. thanks valgrind's
-        memcheck tool.
-
-    *   we should initialize flags before feeding it into
-        "ngx_http_parse_unsafe_uri". thanks valgrind's memcheck tool.
+    (<http://github.com/agentzh/echo-nginx-module>).
 
-    *   fixed a minor issue in the echo_location/echo_subrequest
-        implementation, which used to have race conditions.
+Changes
+    The changes of every release of this module can be obtained from the
+    ngx_openresty bundle's change logs:
 
-  v0.31
-    *   the echo wev handler should not proceed if it is still waiting for
-        some sequential subrequest or has just processed one to avoid
-        bouncing issues.
-
-    *   fixed a segfault for echo_exec for 0.7.x: we should check "r->done"
-        before proceeding.
-
-    *   no longer explicitly set "r->write_event_handler" to
-        "ngx_http_request_empty_handler" because it's totally wrong for the
-        state machine.
-
-    *   fixed the sequential subrequest model bugs: we should ensure the
-        "pr->write_event_handler" gets called immediately after the
-        "post_subrequest" callback when the subrequest finalizes.
-
-  v0.30
-    *   fixed the echo_exec directive for nginx >= 0.8.11. we didn't get the
-        "r->main->count" right in the previous version.
-
-  v0.29
-    *   refactored the core of this module. now the implementation of
-        echo_location, echo_subrequest, echo_sleep, and
-        echo_read_request_body finally fit well with the nginx event model
-        and Igor Sysoev's way of thinking.
-
-  v0.28
-    *   added support for the "-n" and "--" options to the echo,
-        echo_before_body, and echo_after_body directives.
-
-  v0.27
-    *   applied the patch from Sergey A. Osokin to work with nginx 0.8.35.
-
-  v0.26
-    *   bug fix: we should bypass upstream filters in our echo filters. an
-        output filter should ever call "ngx_http_output_filter" nor
-        "ngx_http_send_special".
-
-  v0.25
-    *   now we register a request cleanup handler to ensure our sleep
-        event's timer will always get properly deleted even if the request
-        is quit prematurely. this affects the echo_sleep directive.
-
-    *   use ngx_null_string whenever possible in the source.
-
-    *   sync'd the bundled test scaffold to Test::Nginx 0.07.
-
-  v0.24
-    *   various source file name and coding style fixes. (the code now looks
-        more like Igor Sysoev's.)
-
-  v0.23
-    *   now the subrequest can read the client request body directly (for
-        the main request) because we made subrequests inherit its parent's
-        "r->header_in" as well. This affects the echo_read_request_body
-        directive.
-
-    *   fixed echo_after_body in subrequests by using a hack (checking
-        "cl->buf->sync" for the last buf) for nginx 0.8.7+ only.
-
-    *   added new varaible $echo_response_status to help testing the status
-        code of a subrequest. (The memc module makes use of it.)
-
-    *   use the "ngx_calloc_buf" macro to allocate new bufs in the code
-        rather than explicit "ngx_pcalloc" calls for safety.
-
-  v0.22
-    *   Now we allowed all the directives appear in the rewrite module's if
-        block. But so far I've only tested the echo directive.
-
-  v0.21
-    *   Added a new directive named echo_exec which does internal redirect
-        to other (named) locations.
-
-  v0.20
-    *   Fixed a bug in echo_sleep's "r->main->count" handling for nginx
-        0.8.x. This bug will cause the server to hang when proxing a
-        location with echo_sleep.
-
-    *   Applied the "ngx_str3cmp", "ngx_str4cmp", and "ngx_str6cmp"
-        optimizing macros to the "parse_method_name" function, as suggested
-        by Marcus Clyne.
-
-    *   Added TODO items regarding $echo_random and "echo_repeat" suggested
-        by Marcus Clyne.
-
-  v0.19
-    *   Fixed the CPS-style chained subrequest model for the echo_location
-        and echo_subrequest directives. they are now working perfectly and
-        will not hang the server with the recent nginx 0.8.21 ~ 0.8.27
-        releases. To be specifically, the chained subrequest should call
-        "ngx_http_finalize_request" on its parent request if the content
-        handler of the parent request does not return "NGX_DONE".
-
-    *   Undeprecated the echo_location and echo_subrequest directives.
-
-  v0.18
-    *   Fixed the "zero size buf in output" alerts in error.log.
-
-    *   Added the new directive echo_request_body.
-
-    *   Now we use the "ngx_http_parse_unsafe_uri" function to check the
-        locations to echo_location_async and its friends. Thanks Arvind
-        Jayaprakash for suggesting this fix.
-
-    *   Deprecated the echo_location and echo_subrequest directives.
-
-    *   For HTTP 1.0 clients, use the buf length of the first chain link as
-        the output header Content-Length.
-
-    *   Implemented new variable $echo_incr.
-
-  v0.17
-    *   Added new directives echo_foreach_split and echo_end. Also
-        introduced a "topic variable" named $echo_it.
-
-    *   Added new variables $echo_request_uri and
-        $echo_cacheable_request_uri.
-
-  v0.16
-    *   Now the subrequests issued by the echo_location_async and
-        echo_location directives no longer inherit cached variable values
-        from its parent request. (The underlying "ngx_http_subrequest"
-        function, however, does automatic cachable variable value
-        inheritance.)
-
-    *   Added an undocumented variable *echo_cached_request_uri* to help
-        testing of this module.
-
-  v0.15
-    *   Added new directives echo_subrequest and echo_subrequest_async for
-        the full nginx subrequest API.
-
-    *   Removed the "echo_client_request_headers" directive, and provided
-        the $echo_client_request_headers variable instead.
-
-    *   Added new variables $echo_request_method and
-        $echo_client_request_method.
-
-  v0.14
-    *   Added new directive echo_read_request_body to explicitly read client
-        request body so that the [[NginxHttpCoreModule#$request_body]]
-        variable will always have non-empty values.
-
-    *   Now we shuffer test cases automatically in .t files and fixed bugs
-        in the tests themselves which are hidden by config reload fallback
-        in failure.
-
-  v0.13
-    *   Fixed the special cases when the outputs of a echo_duplicate
-        directive is empty.
-
-    *   Now we explicitly clear content length and accept ranges headers in
-        the content handler.
-
-  v0.12
-    *   Implemented the echo_location directive, which can issue chained GET
-        subrequests in the Continuation Passing Style (CPS), rather than the
-        parallel subrequest issued by the echo_location_async directive.
-
-  v0.11
-    *   Implemented the echo_duplicate directive to help generating large
-        chunk of data for testing.
-
-  v0.10
-    *   Fixed compilation regression against Nginx 0.7.21. This bug appears
-        in version 0.09.
-
-    *   Refactored the codebase by splitting source into various small
-        files.
-
-  v0.09
-    *   Reimplement the echo_sleep directive using per-request event and
-        timer; the old implementation uses the global connection's
-        read/write event to register timer, so it will break horribly when
-        multiple subrequests "sleep" at the same time.
-
-    *   Added the echo_location_async directive which can issue a GET
-        subrequest and insert its contents herein.
-
-  v0.08
-    *   echo_sleep: now we delete our "write event timer" in the
-        "post_sleep" handle.
-
-    *   Added "doc/manpage.wiki" which tracks changes in the wiki page
-        (<http://wiki.nginx.org/NginxHttpEchoModule >).
-
-    *   Added the "util/wiki2pod.pl" script to convert "doc/manpage.wiki" to
-        "README".
-
-    *   Disabled the "DDEBUG" macro in the C source by default.

+Description
+===========
+
+This module wraps lots of Nginx internal APIs for streaming input and output, parallel/sequential subrequests, timers and sleeping, as well as various meta data accessing.
+
+Basically it provides various utilities that help testing and debugging of other modules by trivially emulating different kinds of faked subrequest locations.
+
+People will also find it useful in real-world applications that need to
+
+1. serve static contents directly from memory (loading from the Nginx config file).
+1. wrap the upstream response with custom header and footer (kinda like the [addition module](http://wiki.nginx.org/HttpAdditionModule) but with contents read directly from the config file and Nginx variables).
+1. merge contents of various "Nginx locations" (i.e., subrequests) together in a single main request (using [echo_location](http://wiki.nginx.org/HttpEchoModule#echo_location) and its friends).
+
+This is a special dual-role module that can *lazily* serve as a content handler or register itself as an output filter only upon demand. By default, this module does not do anything at all.
+
+Technially, this module has also demonstrated the following techniques that might be helpful for module writers:
+
+1. Issue parallel subreqeusts directly from content handler.
+1. Issue chained subrequests directly from content handler, by passing continuation along the subrequest chain.
+1. Issue subrequests with all HTTP 1.1 methods and even an optional faked HTTP request body.
+1. Interact with the Nginx event model directly from content handler using custom events and timers, and resume the content handler back if necessary.
+1. Dual-role module that can (lazily) serve as a content handler or an output filter or both.
+1. Nginx config file variable creation and interpolation.
+1. Streaming output control using output_chain, flush and its friends.
+1. Read client request body from the content handler, and returns back (asynchronously) to the content handler after completion.
+1. Use Perl-based declarative [test suite](http://wiki.nginx.org/HttpEchoModule#Test_Suite) to drive the development of Nginx C modules.
+
+Content Handler Directives
+==========================
+
+Use of the following directives register this module to the current Nginx location as a content handler. If you want to use another module, like the [standard proxy module](http://wiki.nginx.org/HttpProxyModule), as the content handler, use the [filter directives](http://wiki.nginx.org/HttpEchoModule#Filter_Directives) provided by this module.
+
+All the content handler directives can be mixed together in a single Nginx location and they're supposed to run sequentially just as in the Bash scripting language.
+
+Every content handler directive supports variable interpolation in its arguments (if any).
+
+The MIME type set by the [standard default_type directive](http://wiki.nginx.org/HttpCoreModule#default_type) is respected by this module, as in:
+
+
+      location /hello {
+        default_type text/plain;
+        echo hello;
+      }
+
+
+Then on the client side:
+
+
+      $ curl -I 'http://localhost/echo'
+      HTTP/1.1 200 OK
+      Server: nginx/0.8.20
+      Date: Sat, 17 Oct 2009 03:40:19 GMT
+      Content-Type: text/plain
+      Connection: keep-alive
+
+
+Since the [v0.22](http://wiki.nginx.org/HttpEchoModule#v0.22) release, all of the directives are allowed in the [rewrite module](http://wiki.nginx.org/HttpRewriteModule)'s [if](http://wiki.nginx.org/HttpRewriteModule#if) directive block, for instance:
+
+
+    location ^~ /if {
+        set $res miss;
+        if ($arg_val ~* '^a') {
+            set $res hit;
+            echo $res;
+        }
+        echo $res;
+    }
+
+
+echo
+----
+**syntax:** *echo [options] &lt;string&gt;...*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Sends arguments joined by spaces, along with a trailing newline, out to the client.
+
+Note that the data might be buffered by Nginx's underlying buffer. To force the output data flushed immediately, use the [echo_flush](http://wiki.nginx.org/HttpEchoModule#echo_flush) command just after `echo`, as in
+
+
+       echo hello world;
+       echo_flush;
+
+
+When no argument is specified, *echo* emits the trailing newline alone, just like the *echo* command in shell.
+
+Variables may appear in the arguments. An example is
+
+
+       echo The current request uri is $request_uri;
+
+
+where [$request_uri](http://wiki.nginx.org/HttpCoreModule#.24request_uri) is a variable exposed by the [HttpCoreModule](http://wiki.nginx.org/HttpCoreModule).
+
+This command can be used multiple times in a single location configuration, as in
+
+
+    location /echo {
+        echo hello;
+        echo world;
+    }
+
+
+The output on the client side looks like this
+
+
+    $ curl 'http://localhost/echo'
+    hello
+    world
+
+
+Special characters like newlines (`\n`) and tabs (`\t`) can be escaped using C-style escaping sequences. But a notable exception is the dollar sign (`$`). As of Nginx 0.8.20, there's still no clean way to esacpe this characters. (A work-around might be to use a `$echo_dollor` variable that is always evaluated to the constant `$` character. This feature will possibly be introduced in a future version of this module.)
+
+As of the echo [v0.28](http://wiki.nginx.org/HttpEchoModule#v0.28) release, one can suppress the trailing newline character in the output by using the `-n` option, as in
+
+
+    location /echo {
+        echo -n "hello, ";
+        echo "world";
+    }
+
+
+Accessing `/echo` gives
+
+
+    $ curl 'http://localhost/echo'
+    hello, world
+
+
+Leading `-n` in variable values won't take effect and will be emitted literally, as in
+
+
+    location /echo {
+        set $opt -n;
+        echo $opt "hello,";
+        echo "world";
+    }
+
+
+This gives the following output
+
+
+    $ curl 'http://localhost/echo'
+    -n hello,
+    world
+
+
+One can output leading `-n` literals and other options using the special `--` option like this
+
+
+    location /echo {
+        echo -- -n is an option;
+    }
+
+
+which yields
+
+
+    $ curl 'http://localhost/echo'
+    -n is an option
+
+
+echo_duplicate
+--------------
+**syntax:** *echo_duplicate &lt;count&gt; &lt;string&gt;*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Outputs duplication of a string indicated by the second argument, using the times specified in the first argument.
+
+For instance,
+
+
+      location /dup {
+          echo_duplicate 3 "abc";
+      }
+
+
+will lead to an output of `"abcabcabc"`.
+
+Underscores are allowed in the count number, just like in Perl. For example, to emit 1000,000,000 instances of `"hello, world"`:
+
+
+      location /many_hellos {
+          echo_duplicate 1000_000_000 "hello, world";
+      }
+
+
+The `count` argument could be zero, but not negative. The second `string` argument could be an empty string ("") likewise.
+
+Unlike the [echo](http://wiki.nginx.org/HttpEchoModule#echo) directive, no trailing newline is appended to the result. So it's possible to "abuse" this directive as a no-trailing-newline version of [echo](http://wiki.nginx.org/HttpEchoModule#echo) by using "count" 1, as in
+
+
+      location /echo_art {
+          echo_duplicate 2 '---';
+          echo_duplicate 1 ' END ';  # we don't want a trailing newline here
+          echo_duplicate 2 '---';
+          echo;  # we want a trailing newline here...
+      }
+
+
+You get
+
+
+      ------ END ------
+
+
+This directive was first introduced in [version 0.11](http://wiki.nginx.org/HttpEchoModule#v0.11).
+
+echo_flush
+----------
+**syntax:** *echo_flush*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Forces the data potentially buffered by underlying Nginx output filters to send immediately to the client side via socket.
+
+Note that techically the command just emits a ngx_buf_t object with `flush` slot set to 1, so certain weird third-party output filter module could still block it before it reaches Nginx's (last) write filter.
+
+This directive does not take any argument.
+
+Consider the following example:
+
+
+      location /flush {
+         echo hello;
+         
+         echo_flush;
+         
+         echo_sleep 1;
+         echo world;
+      }
+
+
+Then on the client side, using curl to access `/flush`, you'll see the "hello" line immediately, but only after 1 second, the last "world" line. Without calling `echo_flush` in the example above, you'll most likely see no output until 1 second is elapsed due to the internal buffering of Nginx.
+
+This directive will fail to flush the output buffer in case of subrequests get involved. Consider the following example:
+
+
+      location /main {
+          echo_location_async /sub;
+          echo hello;
+          echo_flush;
+      }
+      location /sub {
+          echo_sleep 1;
+      }
+
+
+Then the client won't see "hello" appear even if `echo_flush` has been executed before the subrequest to `/sub` has actually started executing. The outputs of `/main` that are sent *after* [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) will be postponed and buffered firmly.
+
+This does *not* apply to outputs sent before the subrequest initiated. For a modified version of the example given above:
+
+
+      location /main {
+          echo hello;
+          echo_flush;
+          echo_location_async /sub;
+      }
+      location /sub {
+          echo_sleep 1;
+      }
+
+
+The client will immediately see "hello" before `/sub` enters sleeping.
+
+See also [echo](http://wiki.nginx.org/HttpEchoModule#echo), [echo_sleep](http://wiki.nginx.org/HttpEchoModule#echo_sleep), and [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async).
+
+echo_sleep
+----------
+**syntax:** *echo_sleep &lt;seconds&gt;*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Sleeps for the time period specified by the argument, which is in seconds.
+
+This operation is non-blocking on server side, so unlike the [echo_blocking_sleep](http://wiki.nginx.org/HttpEchoModule#echo_blocking_sleep) directive, it won't block the whole Nginx worker process.
+
+The period might takes three digits after the decimal point and must be greater than 0.001.
+
+An example is
+
+
+       location /echo_after_sleep {
+           echo_sleep 1.234;
+           echo resumed!;
+       }
+
+
+Behind the scene, it sets up a per-request "sleep" ngx_event_t object, and adds a timer using that custom event to the Nginx event model and just waits for a timeout on that event. Because the "sleep" event is per-request, this directive can work in parallel subrequests.
+
+echo_blocking_sleep
+-------------------
+**syntax:** *echo_blocking_sleep &lt;seconds&gt;*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+This is a blocking version of the [echo_sleep](http://wiki.nginx.org/HttpEchoModule#echo_sleep) directive.
+
+See the documentation of [echo_sleep](http://wiki.nginx.org/HttpEchoModule#echo_sleep) for more detail.
+
+Behind the curtain, it calls the ngx_msleep macro provided by the Nginx core which maps to usleep on POSIX-compliant systems.
+
+Note that this directive will block the current Nginx worker process completely while being executed, so never use it in production environment.
+
+echo_reset_timer
+----------------
+**syntax:** *echo_reset_timer*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Reset the timer begin time to *now*, i.e., the time when this command is executed during request.
+
+The timer begin time is default to the starting time of the current request and can be overridden by this directive, potentially multiple times in a single location. For example:
+
+
+      location /timed_sleep {
+          echo_sleep 0.03;
+          echo "$echo_timer_elapsed sec elapsed.";
+          
+          echo_reset_timer;
+          
+          echo_sleep 0.02;
+          echo "$echo_timer_elapsed sec elapsed.";
+      }
+
+
+The output on the client side might be
+
+
+    $ curl 'http://localhost/timed_sleep'
+    0.032 sec elapsed.
+    0.020 sec elapsed.
+
+
+The actual figures you get on your side may vary a bit due to your system's current activities.
+
+Invocation of this directive will force the underlying Nginx timer to get updated to the current system time (regardless the timer resolution specified elsewhere in the config file). Furthermore, references of the [$echo_timer_elapsed](http://wiki.nginx.org/HttpEchoModule#.24echo_timer_elapsed) variable will also trigger timer update forcibly.
+
+See also [echo_sleep](http://wiki.nginx.org/HttpEchoModule#echo_sleep) and [$echo_timer_elapsed](http://wiki.nginx.org/HttpEchoModule#.24echo_timer_elapsed).
+
+echo_read_request_body
+----------------------
+**syntax:** *echo_read_request_body*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Explicitly reads request body so that the [$request_body](http://wiki.nginx.org/HttpCoreModule#.24request_body) variable will always have non-empty values (unless the body is so big that it has been saved by Nginx to a local temporary file).
+
+Note that this might not be the original client request body because the current request might be a subrequest with a "artificial" body specified by its parent.
+
+This directive does not generate any output itself, just like [echo_sleep](http://wiki.nginx.org/HttpEchoModule#echo_sleep).
+
+Here's an example for echo'ing back the original HTTP client request (both headers and body are included):
+
+
+      location /echoback {
+        echo_duplicate 1 $echo_client_request_headers;
+        echo "\r";
+        echo_read_request_body;
+        echo $request_body;
+      }
+
+
+The content of `/echoback` looks like this on my side (I was using Perl's LWP utility to access this location on the server):
+
+
+      $ (echo hello; echo world) | lwp-request -m POST 'http://localhost/echoback'
+      POST /echoback HTTP/1.1
+      TE: deflate,gzip;q=0.3
+      Connection: TE, close
+      Host: localhost
+      User-Agent: lwp-request/5.818 libwww-perl/5.820
+      Content-Length: 12
+      Content-Type: application/x-www-form-urlencoded
+      
+      hello
+      world
+
+
+Because `/echoback` is the main request, [$request_body](http://wiki.nginx.org/HttpCoreModule#.24request_body) holds the original client request body.
+
+Before Nginx 0.7.56, it makes no sense to use this directive because [$request_body](http://wiki.nginx.org/HttpCoreModule#.24request_body) was first introduced in Nginx 0.7.58.
+
+This directive itself was first introduced in the echo module's [v0.14 release](http://wiki.nginx.org/HttpEchoModule#v0.14).
+
+echo_location_async
+-------------------
+**syntax:** *echo_location_async &lt;location&gt; [&lt;url_args&gt;]*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Issue GET subrequest to the location specified (first argument) with optional url arguments specified in the second argument.
+
+As of Nginx 0.8.20, the `location` argument does *not* support named location, due to a limitation in the `ngx_http_subrequest` function. The same is true for its brother, the [echo_location](http://wiki.nginx.org/HttpEchoModule#echo_location) directive.
+
+A very simple example is
+
+
+    location /main {
+        echo_location_async /sub;
+        echo world;
+    }
+    location /sub {
+        echo hello;
+    }
+
+
+Accessing `/main` gets
+
+
+      hello
+      world
+
+
+Calling multiple locations in parallel is also possible:
+
+
+    location /main {
+        echo_reset_timer;
+        echo_location_async /sub1;
+        echo_location_async /sub2;
+        echo "took $echo_timer_elapsed sec for total.";
+    }
+    location /sub1 {
+        echo_sleep 2; # sleeps 2 sec
+        echo hello;
+    }
+    location /sub2 {
+        echo_sleep 1; # sleeps 1 sec
+        echo world;
+    }
+
+
+Accessing `/main` yields
+
+
+      $ time curl 'http://localhost/main'
+      hello
+      world
+      took 0.000 sec for total.
+      
+      real  0m2.006s
+      user  0m0.000s
+      sys   0m0.004s
+
+
+You can see that the main handler `/main` does *not* wait the subrequests `/sub1` and `/sub2` to complete and quickly goes on, hence the "0.000 sec" timing result. The whole request, however takes approximately 2 sec in total to complete because `/sub1` and `/sub2` run in parallel (or "concurrently" to be more accurate).
+
+If you use [echo_blocking_sleep](http://wiki.nginx.org/HttpEchoModule#echo_blocking_sleep) in the previous example instead, then you'll get the same output, but with 3 sec total response time, because "blocking sleep" blocks the whole Nginx worker process.
+
+Locations can also take an optional querystring argument, for instance
+
+
+    location /main {
+        echo_location_async /sub 'foo=Foo&bar=Bar';
+    }
+    location /sub {
+        echo $arg_foo $arg_bar;
+    }
+
+
+Accessing `/main` yields
+
+
+      $ curl 'http://localhost/main'
+      Foo Bar
+
+
+Querystrings is *not* allowed to be concatenated onto the `location` argument with "?" directly, for example, `/sub?foo=Foo&bar=Bar` is an invalid location, and shouldn't be fed as the first argument to this directive.
+
+Due to an unknown bug in Nginx (it still exists in Nginx 0.8.20), the [standard SSI module](http://wiki.nginx.org/HttpSsiModule) is required to ensure that the contents of the subrequests issued by this directive are correctly merged into the output chains of the main one. Fortunately, the SSI module is enabled by default during Nginx's `configure` process.
+
+If calling this directive without SSI module enabled, you'll get truncated response without contents of any subrequests and get an alert message in your Nginx's `error.log`, like this:
+
+
+      [alert] 24212#0: *1 the http output chain is empty, client: 127.0.0.1, ...
+
+
+Technically speaking, this directive is an example that Nginx content handler issues one or more subrequests directly. AFAIK, the [fancyindex module](https://connectical.com/projects/ngx-fancyindex/wiki) also does such kind of things ;)
+
+Nginx named locations like `@foo` is *not* supported here.
+
+This directive is logically equivalent to the GET version of [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async). For example,
+
+
+      echo_location_async /foo 'bar=Bar';
+
+
+is logically equivalent to
+
+
+      echo_subrequest_async GET /foo -q 'bar=Bar';
+
+
+But calling this directive is slightly faster than calling [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) using `GET` because we don't have to parse the HTTP method names like `GET` and options like `-q`.
+
+This directive is first introduced in [version 0.09](http://wiki.nginx.org/HttpEchoModule#v0.09) of this module and requires at least Nginx 0.7.46.
+
+echo_location
+-------------
+**syntax:** *echo_location &lt;location&gt; [&lt;url_args&gt;]*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Just like the [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) directive, but `echo_location` issues subrequests *in series* rather than in parallel. That is, the content handler directives following this directive won't be executed until the subrequest issued by this directive completes.
+
+The final response body is almost always equivalent to the case when [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) is used instead, only if timing variables is used in the outputs.
+
+Consider the following example:
+
+
+    location /main {
+        echo_reset_timer;
+        echo_location /sub1;
+        echo_location /sub2;
+        echo "took $echo_timer_elapsed sec for total.";
+    }
+    location /sub1 {
+        echo_sleep 2;
+        echo hello;
+    }
+    location /sub2 {
+        echo_sleep 1;
+        echo world;
+    }
+
+
+The location `/main` above will take for total 3 sec to complete (compared to 2 sec if [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) is used instead here). Here's the result in action on my machine:
+
+
+      $ curl 'http://localhost/main'
+      hello
+      world
+      took 3.003 sec for total.
+      
+      real  0m3.027s
+      user  0m0.020s
+      sys   0m0.004s
+
+
+This directive is logically equivalent to the GET version of [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest). For example,
+
+
+      echo_location /foo 'bar=Bar';
+
+
+is logically equivalent to
+
+
+      echo_subrequest GET /foo -q 'bar=Bar';
+
+
+But calling this directive is slightly faster than calling [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest) using `GET` because we don't have to parse the HTTP method names like `GET` and options like `-q`.
+
+Behind the scene, it creates an `ngx_http_post_subrequest_t` object as a *continuation* and passes it into the `ngx_http_subrequest` function call. Nginx will later reopen this "continuation" in the subrequest's `ngx_http_finalize_request` function call. We resumes the execution of the parent-request's content handler and starts to run the next directive (command) if any.
+
+Nginx named locations like `@foo` is *not* supported here.
+
+This directive was first introduced in the [release v0.12](http://wiki.nginx.org/HttpEchoModule#v0.12).
+
+See also [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) for more details about the meaning of the arguments.
+
+echo_subrequest_async
+---------------------
+**syntax:** *echo_subrequest_async &lt;HTTP_method&gt; &lt;location&gt; [-q &lt;url_args&gt;] [-b &lt;request_body&gt;] [-f &lt;request_body_path&gt;]*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Initiate an asynchronous subrequest using HTTP method, an optional url arguments (or querystring) and an optional request body which can be defined as a string or as a path to a file which contains the body.
+
+This directive is very much like a generalized version of the [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) directive.
+
+Here's a small example demonstrating its usage:
+
+
+    location /multi {
+        # body defined as string
+        echo_subrequest_async POST '/sub' -q 'foo=Foo' -b 'hi';
+        # body defined as path to a file, relative to nginx prefix path if not absolute
+        echo_subrequest_async PUT '/sub' -q 'bar=Bar' -f '/tmp/hello.txt';
+    }
+    location /sub {
+        echo "querystring: $query_string";
+        echo "method: $echo_request_method";
+        echo "body: $echo_request_body";
+        echo "content length: $http_content_length";
+        echo '///';
+    }
+
+
+Then on the client side:
+
+
+      $ echo -n hello > /tmp/hello.txt
+      $ curl 'http://localhost/multi'
+      querystring: foo=Foo
+      method: POST
+      body: hi
+      content length: 2
+      ///
+      querystring: bar=Bar
+      method: PUT
+      body: hello
+      content length: 5
+      ///
+
+
+Here's more funny example using the standard [proxy module](http://wiki.nginx.org/HttpEchoModule#HttpProxyModule) to handle the subrequest:
+
+
+    location /main {
+        echo_subrequest_async POST /sub -b 'hello, world';
+    }
+    location /sub {
+        proxy_pass $scheme://127.0.0.1:$server_port/proxied;
+    }
+    location /proxied {
+        echo "method: $echo_request_method.";
+        
+        # we need to read body explicitly here...or $echo_request_body
+        #   will evaluate to empty ("")
+        echo_read_request_body;
+        
+        echo "body: $echo_request_body.";
+    }
+
+
+Then on the client side, we can see that
+
+
+      $ curl 'http://localhost/main'
+      method: POST.
+      body: hello, world.
+
+
+Nginx named locations like `@foo` is *not* supported here.
+
+This directive was first introduced in the [release v0.15](http://wiki.nginx.org/HttpEchoModule#v0.15).
+
+The `-f` option to define a file path for the body was introduced in the [release v0.35](http://wiki.nginx.org/HttpEchoModule#v0.35).
+
+See also the [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest) and [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) directives.
+
+echo_subrequest
+---------------
+**syntax:** *echo_subrequest_async &lt;HTTP_method&gt; &lt;location&gt; [-q &lt;url_args&gt;] [-b &lt;request_body&gt;] [-f &lt;request_body_path&gt;]*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+This is the synchronous version of the [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) directive. And just like [echo_location](http://wiki.nginx.org/HttpEchoModule#echo_location), it does not block the Nginx worker process (while [echo_blocking_sleep](http://wiki.nginx.org/HttpEchoModule#echo_blocking_sleep) does), rather, it uses continuation to pass control along the subrequest chain.
+
+See [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) for more details.
+
+Nginx named locations like `@foo` is *not* supported here.
+
+This directive was first introduced in the [release v0.15](http://wiki.nginx.org/HttpEchoModule#v0.15).
+
+echo_foreach_split
+------------------
+**syntax:** *echo_foreach_split &lt;delimiter&gt; &lt;string&gt;*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Split the second argument `string` using the delimiter specified in the first argument, and then iterate through the resulting items. For instance:
+
+
+      location /loop {
+        echo_foreach_split ',' $arg_list;
+          echo "item: $echo_it";
+        echo_end;
+      }
+
+
+Accessing /main yields
+
+
+      $ curl 'http://localhost/loop?list=cat,dog,mouse'
+      item: cat
+      item: dog
+      item: mouse
+
+
+As seen in the previous example, this directive should always be accompanied by an [echo_end](http://wiki.nginx.org/HttpEchoModule#echo_end) directive.
+
+Parallel `echo_foreach_split` loops are allowed, but nested ones are currently forbidden.
+
+The `delimiter` argument could contain *multiple* arbitrary characters, like
+
+
+      echo_foreach_split '-a-' 'cat-a-dog-a-mouse';
+        echo $echo_it;
+      echo_end;
+
+
+Logically speaking, this looping structure is just the `foreach` loop combined with a `split` function call in Perl (using the previous example):
+
+
+       foreach (split ',', $arg_list) {
+           print "item $_\n";
+       }
+
+
+People will also find it useful in merging multiple `.js` or `.css` resources into a whole. Here's an example:
+
+
+      location /merge {
+          default_type 'text/javascript';
+          
+          echo_foreach_split '&' $query_string;
+              echo "/* JS File $echo_it */";
+              echo_location_async $echo_it;
+              echo;
+          echo_end;
+      }
+
+
+Then accessing /merge to merge the `.js` resources specified in the query string:
+
+
+      $ curl 'http://localhost/merge?/foo/bar.js&/yui/blah.js&/baz.js'
+
+
+One can also use third-party Nginx cache module to cache the merged response generated by the `/merge` location in the previous example.
+
+This directive was first introduced in the [release v0.17](http://wiki.nginx.org/HttpEchoModule#v0.17).
+
+echo_end
+--------
+**syntax:** *echo_end*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+This directive is used to terminate the body of looping and conditional control structures like [echo_foreach_split](http://wiki.nginx.org/HttpEchoModule#echo_foreach_split).
+
+This directive was first introduced in the [release v0.17](http://wiki.nginx.org/HttpEchoModule#v0.17).
+
+echo_request_body
+-----------------
+**syntax:** *echo_request_body*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Outputs the contents of the request body previous read.
+
+Behind the scene, it's implemented roughly like this:
+
+
+      if (r->request_body && r->request_body->bufs) {
+          return ngx_http_output_filter(r, r->request_body->bufs);
+      }
+
+
+Unlike the [$echo_request_body](http://wiki.nginx.org/HttpEchoModule#.24echo_request_body) and $request_body variables, this directive will show the whole request body even if some parts or all parts of it are saved in temporary files on the disk.
+
+It is a "no-op" if no request body has been read yet.
+
+This directive was first introduced in the [release v0.18](http://wiki.nginx.org/HttpEchoModule#v0.18).
+
+See also [echo_read_request_body](http://wiki.nginx.org/HttpEchoModule#echo_read_request_body) and the [chunkin module](http://wiki.nginx.org/HttpChunkinModule).
+
+echo_exec
+---------
+**syntax:** *echo_exec &lt;location&gt; [&lt;query_string&gt;]*
+
+**syntax:** *echo_exec &lt;named_location&gt;*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Does an internal redirect to the location specified. An optional query string can be specified for normal locations, as in
+
+
+      location /foo {
+          echo_exec /bar weight=5;
+      }
+      location /bar {
+          echo $arg_weight;
+      }
+
+
+Or equivalently
+
+
+      location /foo {
+          echo_exec /bar?weight=5;
+      }
+      location /bar {
+          echo $arg_weight;
+      }
+
+
+Named locations are also supported. Here's an example:
+
+
+      location /foo {
+          echo_exec @bar;
+      }
+      location @bar {
+          # you'll get /foo rather than @bar
+          #  due to a potential bug in nginx.
+          echo $echo_request_uri;
+      }
+
+
+But query string (if any) will always be ignored for named location redirects due to a limitation in the `ngx_http_named_location` function.
+
+Never try to echo things before the `echo_exec` directive or you won't see the proper response of the location you want to redirect to. Because any echoing will cause the original location handler to send HTTP headers before the redirection happens.
+
+Technically speaking, this directive exposes the Nginx internal API functions `ngx_http_internal_redirect` and `ngx_http_named_location`.
+
+This directive was first introduced in the [v0.21 release](http://wiki.nginx.org/HttpEchoModule#v0.21).
+
+echo_status
+-----------
+**syntax:** *echo_status &lt;status-num&gt;*
+
+**default:** *echo_status 200*
+
+**context:** *location, location if*
+
+**phase:** *content*
+
+Specify the default response status code. Default to `200`. This directive is declarative and the relative order with other echo-like directives is not important.
+
+Here is an example,
+
+
+    location = /bad {
+        echo_status 404;
+        echo "Something is missing...";
+    }
+
+
+then we get a response like this:
+
+
+    HTTP/1.1 404 Not Found
+    Server: nginx/1.2.1
+    Date: Sun, 24 Jun 2012 03:58:18 GMT
+    Content-Type: text/plain
+    Transfer-Encoding: chunked
+    Connection: keep-alive
+
+    Something is missing...
+
+
+This directive was first introduced in the `v0.40` release.
+
+Filter Directives
+=================
+
+Use of the following directives trigger the filter registration of this module. By default, no filter will be registered by this module.
+
+Every filter directive supports variable interpolation in its arguments (if any).
+
+echo_before_body
+----------------
+**syntax:** *echo_before_body [options] [argument]...*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *output filter*
+
+It's the filter version of the [echo](http://wiki.nginx.org/HttpEchoModule#echo) directive, and prepends its output to the beginning of the original outputs generated by the underlying content handler.
+
+An example is
+
+
+    location /echo {
+        echo_before_body hello;
+        proxy_pass $scheme://127.0.0.1:$server_port$request_uri/more;
+    }
+    location /echo/more {
+        echo world
+    }
+
+
+Accessing `/echo` from the client side yields
+
+
+      hello
+      world
+
+
+In the previous sample, we borrow the [standard proxy module](http://wiki.nginx.org/HttpProxyModule) to serve as the underlying content handler that generates the "main contents".
+
+Multiple instances of this filter directive are also allowed, as in:
+
+
+    location /echo {
+        echo_before_body hello;
+        echo_before_body world;
+        echo !;
+    }
+
+
+On the client side, the output is like
+
+
+      $ curl 'http://localhost/echo'
+      hello
+      world
+      !
+
+
+In this example, we also use the [content handler directives](http://wiki.nginx.org/HttpEchoModule#Content_Handler_Directives) provided by this module as the underlying content handler.
+
+This directive also supports the `-n` and `--` options like the [echo](http://wiki.nginx.org/HttpEchoModule#echo) directive.
+
+This directive can be mixed with its brother directive [echo_after_body](http://wiki.nginx.org/HttpEchoModule#echo_after_body).
+
+echo_after_body
+---------------
+**syntax:** *echo_after_body [argument]...*
+
+**default:** *no*
+
+**context:** *location, location if*
+
+**phase:** *output filter*
+
+**WARNING** this directive does not work for nginx >= 0.7.65.
+
+It's very much like the [echo_before_body](http://wiki.nginx.org/HttpEchoModule#echo_before_body) directive, but *appends* its output to the end of the original outputs generated by the underlying content handler.
+
+Here's a simple example:
+
+
+    location /echo {
+        echo_after_body hello;
+        proxy_pass http://127.0.0.1:$server_port$request_uri/more;
+    }
+    location /echo/more {
+        echo world
+    }
+
+
+Accessing `/echo` from the client side yields
+
+
+      world
+      hello
+
+
+Multiple instances are allowed, as in:
+
+
+    location /echo {
+        echo_after_body hello;
+        echo_after_body world;
+        echo i;
+        echo say;
+    }
+
+
+The output on the client side while accessing the `/echo` location looks like
+
+
+      i
+      say
+      hello
+      world
+
+
+This directive also supports the `-n` and `--` options like the [echo](http://wiki.nginx.org/HttpEchoModule#echo) directive.
+
+When this directive is used in a location accessed by a subrequest, it replies on the `sync` flag set in a chain buffer to indicate the end of the output for nginx >= 0.8.7. This is a hack because Nginx does not provide a reliable way to determine the end of the output chain in a subrequest's output filter. Use it in subrequests with care.
+
+This directive can be mixed with its brother directive [echo_before_body](http://wiki.nginx.org/HttpEchoModule#echo_before_body).
+
+Variables
+=========
+
+$echo_it
+--------
+
+This is a "topic variable" used by [echo_foreach_split](http://wiki.nginx.org/HttpEchoModule#echo_foreach_split), just like the `$_` variable in Perl.
+
+$echo_timer_elapsed
+-------------------
+
+This variable holds the seconds elapsed since the start of the current request (might be a subrequest though) or the last invocation of the [echo_reset_timer](http://wiki.nginx.org/HttpEchoModule#echo_reset_timer) command.
+
+The timing result takes three digits after the decimal point.
+
+References of this variable will force the underlying Nginx timer to update to the current system time, regardless the timer resolution settings elsewhere in the config file, just like the [echo_reset_timer](http://wiki.nginx.org/HttpEchoModule#echo_reset_timer) directive.
+
+$echo_request_body
+------------------
+
+Evaluates to the current (sub)request's request body previously read if no part of the body has been saved to a temporary file. To always show the request body even if it's very large, use the [echo_request_body](http://wiki.nginx.org/HttpEchoModule#echo_request_body) directive.
+
+$echo_request_method
+--------------------
+
+Evaluates to the HTTP request method of the current request (it can be a subrequest).
+
+Behind the scene, it just takes the string data stored in `r->method_name`.
+
+Compare it to the [$echo_client_request_method](http://wiki.nginx.org/HttpEchoModule#.24echo_client_request_method) variable.
+
+At least for Nginx 0.8.20 and older, the [$request_method](http://wiki.nginx.org/HttpCoreModule#.24request_method) variable provided by the [http core module](http://wiki.nginx.org/HttpCoreModule) is actually doing what our [$echo_client_request_method](http://wiki.nginx.org/HttpEchoModule#.24echo_client_request_method) is doing.
+
+This variable was first introduced in our [v0.15 release](http://wiki.nginx.org/HttpEchoModule#v0.15).
+
+$echo_client_request_method
+---------------------------
+
+Always evaluates to the main request's HTTP method even if the current request is a subrequest.
+
+Behind the scene, it just takes the string data stored in `r->main->method_name`.
+
+Compare it to the [$echo_request_method](http://wiki.nginx.org/HttpEchoModule#.24echo_request_method) variable.
+
+This variable was first introduced in our [v0.15 release](http://wiki.nginx.org/HttpEchoModule#v0.15).
+
+$echo_client_request_headers
+----------------------------
+
+Evaluates to the original client request's headers.
+
+Just as the name suggests, it will always take the main request (or the client request) even if it's currently executed in a subrequest.
+
+A simple example is below:
+
+
+      location /echoback {
+         echo "headers are:"
+         echo $echo_client_request_headers;
+      }
+
+
+Accessing `/echoback` yields
+
+
+      $ curl 'http://localhost/echoback'
+      headers are
+      GET /echoback HTTP/1.1
+      User-Agent: curl/7.18.2 (i486-pc-linux-gnu) libcurl/7.18.2 OpenSSL/0.9.8g
+      Host: localhost:1984
+      Accept: */*
+
+
+Behind the scene, it recovers `r->main->header_in` on the C level and does not construct the headers itself by traversing parsed results in the request object, and strips the last (trailing) CRLF.
+
+This variable was first introduced in [version 0.15](http://wiki.nginx.org/HttpEchoModule#v0.15).
+
+$echo_cacheable_request_uri
+---------------------------
+
+Evaluates to the parsed form of the URI (usually led by `/`) of the current (sub-)request. Unlike the [$echo_request_uri](http://wiki.nginx.org/HttpEchoModule#.24echo_request_uri) variable, it is cacheable.
+
+See [$echo_request_uri](http://wiki.nginx.org/HttpEchoModule#.24echo_request_uri) for more details.
+
+This variable was first introduced in [version 0.17](http://wiki.nginx.org/HttpEchoModule#v0.17).
+
+$echo_request_uri
+-----------------
+
+Evaluates to the parsed form of the URI (usually led by `/`) of the current (sub-)request. Unlike the [$echo_cacheable_request_uri](http://wiki.nginx.org/HttpEchoModule#.24echo_cacheable_request_uri) variable, it is *not* cacheable.
+
+This is quite different from the [$request_uri](http://wiki.nginx.org/HttpCoreModule#.24request_uri) variable exported by the [HttpCoreModule](http://wiki.nginx.org/HttpCoreModule), because `$request_uri` is the *unparsed* form of the current request's URI.
+
+This variable was first introduced in [version 0.17](http://wiki.nginx.org/HttpEchoModule#v0.17).
+
+$echo_incr
+----------
+
+It is a counter that always generate the current counting number, starting from 1. The counter is always associated with the main request even if it is accessed within a subrequest.
+
+Consider the following example
+
+
+    location /main {
+        echo "main pre: $echo_incr";
+        echo_location_async /sub;
+        echo_location_async /sub;
+        echo "main post: $echo_incr";
+    }
+    location /sub {
+        echo "sub: $echo_incr";
+    }
+
+
+Accessing `/main` yields
+
+    main pre: 1
+    sub: 3
+    sub: 4
+    main post: 2
+
+This directive was first introduced in the [v0.18 release](http://wiki.nginx.org/HttpEchoModule#v0.18).
+
+$echo_response_status
+---------------------
+
+Evaluates to the status code of the current (sub)request, null if not any.
+
+Behind the scene, it's just the textual representation of `r->headers_out->status`.
+
+This directive was first introduced in the [v0.23 release](http://wiki.nginx.org/HttpEchoModule#v0.23).
+
+Installation
+============
+
+You're recommended to install this module (as well as the Nginx core and many other goodies) via the [ngx_openresty bundle](http://openresty.org). See [the detailed instructions](http://openresty.org/#Installation) for downloading and installing ngx_openresty into your system. This is the easiest and most safe way to set things up.
+
+Alternatively, you can install this module manually with the Nginx source:
+
+Grab the nginx source code from [nginx.org](http://nginx.org/), for example,
+the version 1.2.1 (see [nginx compatibility](http://wiki.nginx.org/HttpEchoModule#Compatibility)), and then build the source with this module:
+
+
+    $ wget 'http://sysoev.ru/nginx/nginx-1.2.1.tar.gz'
+    $ tar -xzvf nginx-1.2.1.tar.gz
+    $ cd nginx-1.2.1/
+    
+    # Here we assume you would install you nginx under /opt/nginx/.
+    $ ./configure --prefix=/opt/nginx \
+        --add-module=/path/to/echo-nginx-module
+     
+    $ make -j2
+    $ make install
+
+
+Download the latest version of the release tarball of this module from [echo-nginx-module file list](http://github.com/agentzh/echo-nginx-module/tags).
+
+Also, this module is included and enabled by default in the [ngx_openresty bundle](http://openresty.org).
+
+Compatibility
+=============
+
+The following versions of Nginx should work with this module:
+
+* **1.2.x**                       (last tested: 1.2.1)
+* **1.1.x**                       (last tested: 1.1.5)
+* **1.0.x**                       (last tested: 1.0.11)
+* **0.9.x**                       (last tested: 0.9.4)
+* **0.8.x**                       (last tested: 0.8.54)
+* **0.7.x >= 0.7.21**             (last tested: 0.7.68)
+
+In particular,
+
+* the directive [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async) and its brother [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) do *not* work with **0.7.x < 0.7.46**.
+* the [echo_after_body](http://wiki.nginx.org/HttpEchoModule#echo_after_body) directive does *not* work at all with nginx **< 0.8.7**.
+* the [echo_sleep](http://wiki.nginx.org/HttpEchoModule#echo_sleep) directive cannot be used after [echo_location](http://wiki.nginx.org/HttpEchoModule#echo_location) or [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest) for nginx **< 0.8.11**.
+
+Earlier versions of Nginx like 0.6.x and 0.5.x will *not* work at all.
+
+If you find that any particular version of Nginx above 0.7.21 does not work with this module, please consider [reporting a bug](http://wiki.nginx.org/HttpEchoModule#Report_Bugs).
+
+Modules that use this module for testing
+========================================
+
+The following modules take advantage of this `echo` module in their test suite:
+
+* The [memc](http://wiki.nginx.org/HttpMemcModule) module that supports almost the whole memcached TCP protocol.
+* The [chunkin](http://wiki.nginx.org/HttpChunkinModule) module that adds HTTP 1.1 chunked input support to Nginx.
+* The [headers_more](http://wiki.nginx.org/HttpHeadersMoreModule) module that allows you to add, set, and clear input and output headers under the conditions that you specify.
+* The `echo` module itself.
+
+Please mail me other modules that use `echo` in any form and I'll add them to the list above :)
+
+Limitations
+===========
+
+By design, all of this module's directives do not inherit between nested locations. So nginx's `if` may not be used this way:
+
+
+    ? location /foo {
+    ?    set $a 32;
+    ?    if ($a = 32) {
+    ?        set $a 56;
+    ?    }
+    ?
+    ?    echo $a;
+    ? }

+Changes
+=======
+
+The changes of every release of this module can be obtained from the ngx_openresty bundle's change logs:
+
+<http://openresty.org/#Changes>
+
+Test Suite
+==========
+
+This module comes with a Perl-driven test suite. The [test cases](http://github.com/agentzh/echo-nginx-module/tree/master/t/) are
+[declarative](http://github.com/agentzh/echo-nginx-module/blob/master/t/echo.t) too. Thanks to the [Test::Nginx](http://search.cpan.org/perldoc?Test::Nginx) module in the Perl world.
+
+To run it on your side:
+
+
+    $ PATH=/path/to/your/nginx-with-echo-module:$PATH prove -r t
+
+
+You need to terminate any Nginx processes before running the test suite if you have changed the Nginx server binary.
+
+Because a single nginx server (by default, `localhost:1984`) is used across all the test scripts (`.t` files), it's meaningless to run the test suite in parallel by specifying `-jN` when invoking the `prove` utility.
+
+Some parts of the test suite requires standard modules [proxy](http://wiki.nginx.org/HttpProxyModule), [rewrite](http://wiki.nginx.org/HttpRewriteModule) and [SSI](http://wiki.nginx.org/HttpSsiModule) to be enabled as well when building Nginx.
+
+TODO
+====
+
+* Fix the [echo_after_body](http://wiki.nginx.org/HttpEchoModule#echo_after_body) directive in subrequests.
+* Add directives *echo_read_client_request_body* and *echo_request_headers*.
+* Add new directive *echo_log* to use Nginx's logging facility directly from the config file and specific loglevel can be specified, as in
+
+
+      echo_log debug "I am being called.";
+
+
+* Add support for options `-h` and `-t` to [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) and [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest). For example
+
+
+      echo_subrequest POST /sub -q 'foo=Foo&bar=Bar' -b 'hello' -t 'text/plan' -h 'X-My-Header: blah blah'
+
+
+* Add options to control whether a subrequest should inherit cached variables from its parent request (i.e. the current request that is calling the subrequest in question). Currently none of the subrequests issued by this module inherit the cached variables from the parent request.
+* Add new variable *$echo_active_subrequests* to show `r->main->count - 1`.
+* Add the *echo_file* and *echo_cached_file* directives.
+* Add new varaible *$echo_request_headers* to accompany the existing [$echo_client_request_headers](http://wiki.nginx.org/HttpEchoModule#.24echo_client_request_headers) variable.
+* Add new directive *echo_foreach*, as in
+
+
+      echo_foreach 'cat' 'dog' 'mouse';
+        echo_location_async "/animals/$echo_it";
+      echo_end;
+
+
+* Add new directive *echo_foreach_range*, as in
+
+
+      echo_foreach_range '[1..100]' '[a-zA-z0-9]';
+        echo_location_async "/item/$echo_it";
+      echo_end;
+
+
+* Add new directive *echo_repeat*, as in
+
+
+      echo_repeat 10 $i {
+          echo "Page $i";
+          echo_location "/path/to/page/$i";
+      }
+
+
+This is just another way of saying
+
+
+      echo_foreach_range $i [1..10];
+          echo "Page $i";
+          echo_location "/path/to/page/$i";
+      echo_end;
+
+
+Thanks Marcus Clyne for providing this idea.
+
+* Add new variable $echo_random which always returns a random non-negative integer with the lower/upper limit specified by the new directives `echo_random_min` and `echo_random_max`. For example,
+
+
+      echo_random_min  10
+      echo_random_max  200
+      echo "random number: $echo_random";
+
+
+Thanks Marcus Clyne for providing this idea.

-== v0.36 ==
-* now we back-ported the subrequest mechanism of ngx_lua to ngx_echo. this also helps some crazy test cases of mixing echo_location and echo_location_async pass now.
-* now echo_location and its friends can work with ngx_xss (as well as other output filter modules) completely. thanks wd for reporting this issue.
-* done some minor optimization when modifying subrequest's content-length header.
-* now we always pad a trailing \0 to filepath in "echo_subrequest(_async) METHOD /path -f filepath" because ngx_open_cached_file requires a C string file name. thanks dr-dr xp.
-* made our filter optimization works with nginx HUP by clearing the ngx_http_echo_filter_used flag at nginx pre-config callback. thanks Marcus Clyne.
-
-== v0.35 ==
-* added the <code>-f /path/to/file</code> option to the [[#echo_subrequest|echo_subrequest]] and [[#echo_subrequest_async|echo_subrequest_async]] directives to allow POST/PUT a disk file in the subrequest. thanks [https://github.com/dobe Bernd Dorn].
-
-== v0.34 ==
-* we no longer use the problematic <code>ngx_strXcmp</code> macros in our source because it may cause invalid reads and thus segmentation faults. thanks Piotr Sikora.
-
-== v0.33 ==
-* fixed compatibility with nginx 0.7.66+ because the ngx_time_update macro's parameter list has changed. thanks Guang Feng (蔡镜明).
-
-== v0.32 ==
-* we should have used <code>ngx_calloc_buf</code> instead of <code>ngx_alloc_buf</code> for the last chunk generated for [[#echo_after_body|echo_after_body]]. thanks valgrind's memcheck tool.
-* we should initialize flags before feeding it into <code>ngx_http_parse_unsafe_uri</code>. thanks valgrind's memcheck tool.
-* fixed a minor issue in the [[#echo_location|echo_location]]/[[#echo_subrequest|echo_subrequest]] implementation, which used to have race conditions.
-
-== v0.31 ==
-
-* the echo wev handler should not proceed if it is still waiting for some sequential subrequest or has just processed one to avoid bouncing issues.
-* fixed a segfault for echo_exec for 0.7.x: we should check <code>r->done</code> before proceeding.
-* no longer explicitly set <code>r->write_event_handler</code> to <code>ngx_http_request_empty_handler</code> because it's totally wrong for the state machine.
-* fixed the sequential subrequest model bugs: we should ensure the <code>pr->write_event_handler</code> gets called immediately after the <code>post_subrequest</code> callback when the subrequest finalizes.
-
-== v0.30 ==
-
-* fixed the [[#echo_exec|echo_exec]] directive for nginx >= 0.8.11. we didn't get the <code>r->main->count</code> right in the previous version.
-
-== v0.29 ==
-
-* refactored the core of this module. now the implementation of [[#echo_location|echo_location]], [[#echo_subrequest|echo_subrequest]], [[#echo_sleep|echo_sleep]], and [[#echo_read_request_body|echo_read_request_body]] finally fit well with the nginx event model and Igor Sysoev's way of thinking.
-
-== v0.28 ==
-
-* added support for the <code>-n</code> and <code>--</code> options to the [[#echo|echo]], [[#echo_before_body|echo_before_body]], and [[#echo_after_body|echo_after_body]] directives.
-
-== v0.27 ==
-
-* applied the patch from Sergey A. Osokin to work with nginx 0.8.35.
+= Community =
 
-== v0.26 ==
+== English Mailing List ==
 
-* bug fix: we should bypass upstream filters in our echo filters. an output filter should ever call <code>ngx_http_output_filter</code> nor <code>ngx_http_send_special</code>.
+The [https://groups.google.com/group/openresty-en openresty-en] mailing list is for English speakers.
 
-== v0.25 ==
+== Chinese Mailing List ==
 
-* now we register a request cleanup handler to ensure our sleep event's timer will always get properly deleted even if the request is quit prematurely. this affects the echo_sleep directive.
-* use ngx_null_string whenever possible in the source.
-* sync'd the bundled test scaffold to Test::Nginx 0.07.
+The [https://groups.google.com/group/openresty openresty] mailing list is for Chinese speakers.
 
-== v0.24 ==
-
-* various source file name and coding style fixes. (the code now looks more like Igor Sysoev's.)
-
-== v0.23 ==
-
-* now the subrequest can read the client request body directly (for the main request) because we made subrequests inherit its parent's <code>r->header_in</code> as well. This affects the [[#echo_read_request_body|echo_read_request_body]] directive.
-* fixed [[#echo_after_body|echo_after_body]] in subrequests by using a hack (checking <code>cl->buf->sync</code> for the last buf) for nginx 0.8.7+ only.
-* added new varaible [[#$echo_response_status|$echo_response_status]] to help testing the status code of a subrequest. (The [[NginxHttpMemcModule|memc]] module makes use of it.)
-* use the <code>ngx_calloc_buf</code> macro to allocate new bufs in the code rather than explicit <code>ngx_pcalloc</code> calls for safety.
-
-== v0.22 ==
-
-* Now we allowed all the directives appear in the [[NginxHttpRewriteModule|rewrite module]]'s [[NginxHttpRewriteModule#if|if]] block. But so far I've only tested the [[#echo|echo]] directive.
-
-== v0.21 ==
-
-* Added a new directive named [[#echo_exec|echo_exec]] which does internal redirect to other (named) locations.
-
-== v0.20 ==
-
-* Fixed a bug in [[#echo_sleep|echo_sleep]]'s <code>r->main->count</code> handling for nginx 0.8.x. This bug will cause the server to hang when proxing a location with [[#echo_sleep|echo_sleep]].
-* Applied the <code>ngx_str3cmp</code>, <code>ngx_str4cmp</code>, and <code>ngx_str6cmp</code> optimizing macros to the <code>parse_method_name</code> function, as suggested by Marcus Clyne.
-* Added [[#TODO|TODO items]] regarding <code>$echo_random</code> and <code>echo_repeat</code> suggested by Marcus Clyne.
-
-== v0.19 ==
-* Fixed the CPS-style chained subrequest model for the [[#echo_location|echo_location]] and [[#echo_subrequest|echo_subrequest]] directives. they are now working perfectly and will not hang the server with the recent nginx 0.8.21 ~ 0.8.27 releases. To be specifically, the chained subrequest should call <code>ngx_http_finalize_request</code> on its parent request if the content handler of the parent request does not return <code>NGX_DONE</code>.
-* Undeprecated the [[#echo_location|echo_location]] and [[#echo_subrequest|echo_subrequest]] directives.
-
-== v0.18 ==
-* Fixed the "zero size buf in output" alerts in error.log.
-* Added the new directive [[#echo_request_body|echo_request_body]].
-* Now we use the <code>ngx_http_parse_unsafe_uri</code> function to check the locations to [[#echo_location_async|echo_location_async]] and its friends. Thanks Arvind Jayaprakash for suggesting this fix.
-* Deprecated the [[#echo_location|echo_location]] and [[#echo_subrequest|echo_subrequest]] directives.
-* For HTTP 1.0 clients, use the buf length of the first chain link as the output header Content-Length.
-* Implemented new variable [[#$echo_incr|$echo_incr]].
-
-== v0.17 ==
-* Added new directives [[#echo_foreach_split|echo_foreach_split]] and [[#echo_end|echo_end]]. Also introduced a "topic variable" named [[#$echo_it|$echo_it]].
-* Added new variables [[#$echo_request_uri|$echo_request_uri]] and [[#$echo_cacheable_request_uri|$echo_cacheable_request_uri]].
-
-== v0.16 ==
-* Now the subrequests issued by the [[#echo_location|echo_location_async]] and [[#echo_location|echo_location]] directives no longer inherit cached variable values from its parent request. (The underlying <code>ngx_http_subrequest</code> function, however, does automatic cachable variable value inheritance.)
-* Added an undocumented variable ''echo_cached_request_uri'' to help testing of this module.
-
-== v0.15 ==
-
-* Added new directives [[#echo_subrequest|echo_subrequest]] and [[#echo_subrequest_async|echo_subrequest_async]] for the full nginx subrequest API.
-* Removed the <code>echo_client_request_headers</code> directive, and provided the [[#$echo_client_request_headers|$echo_client_request_headers]] variable instead.
-* Added new variables [[#$echo_request_method|$echo_request_method]] and [[#$echo_client_request_method|$echo_client_request_method]].
-
-== v0.14 ==
-
-* Added new directive [[#echo_read_request_body|echo_read_request_body]] to explicitly read client request body so that the [[NginxHttpCoreModule#$request_body]] variable will always have non-empty values.
-* Now we shuffer test cases automatically in .t files and fixed bugs in the tests themselves which are hidden by config reload fallback in failure.
-
-== v0.13 ==
-
-* Fixed the special cases when the outputs of a [[#echo_duplicate|echo_duplicate]] directive is empty.
-* Now we explicitly clear content length and accept ranges headers in the content handler.
-
-== v0.12 ==
-
-* Implemented the [[#echo_location|echo_location]] directive, which can issue chained GET subrequests in the Continuation Passing Style (CPS), rather than the parallel subrequest issued by the [[#echo_location_async|echo_location_async]] directive.
-
-== v0.11 ==
+= Report Bugs =
 
-* Implemented the [[#echo_duplicate|echo_duplicate]] directive to help generating large chunk of data for testing.
+Although a lot of effort has been put into testing and code tuning, there must be some serious bugs lurking somewhere in this module. So whenever you are bitten by any quirks, please don't hesitate to

+# create a ticket on the [http://github.com/agentzh/echo-nginx-module/issues issue tracking interface] provided by GitHub,
+# or send a bug report, questions, or even patches to the [[#Community|OpenResty Community]].
 
-* Fixed compilation regression against Nginx 0.7.21. This bug appears in version 0.09.
-* Refactored the codebase by splitting source into various small files.
+= Source Repository =
 
-== v0.09 ==
+Available on github at [http://github.com/agentzh/echo-nginx-module agentzh/echo-nginx-module].
 
-* Reimplement the [[#echo_sleep|echo_sleep]] directive using per-request event and timer; the old implementation uses the global connection's read/write event to register timer, so it will break horribly when multiple subrequests "sleep" at the same time.
-* Added the [[#echo_location_async|echo_location_async]] directive which can issue a GET subrequest and insert its contents herein.
+= Changes =
 
-== v0.08 ==
+The changes of every release of this module can be obtained from the ngx_openresty bundle's change logs:
 
-* [[#echo_sleep|echo_sleep]]: now we delete our <code>write event timer</code> in the <code>post_sleep</code> handle.
-* Added <code>doc/manpage.wiki</code> which tracks changes in the [http://wiki.nginx.org/NginxHttpEchoModule wiki page].
-* Added the <code>util/wiki2pod.pl</code> script to convert <code>doc/manpage.wiki</code> to <code>README</code>.
-* Disabled the <code>DDEBUG</code> macro in the C source by default.

 You need to terminate any Nginx processes before running the test suite if you have changed the Nginx server binary.
 
-At the moment, [http://search.cpan.org/perldoc?LWP::UserAgent LWP::UserAgent] is used by the [http://github.com/agentzh/echo-nginx-module/blob/master/test/lib/Test/Nginx/Echo.pm test scaffold] for simplicity and it's rather weak in testing ''streaming'' behavior of Nginx (I'm using "curl" to test these aspects manually for now). I'm considering coding up my own Perl HTTP client library based on [http://search.cpan.org/perldoc?IO::Select IO::Select] and [http://search.cpan.org/perldoc?IO::Socket IO::Socket] (there might be already one around?).
-
 Because a single nginx server (by default, <code>localhost:1984</code>) is used across all the test scripts (<code>.t</code> files), it's meaningless to run the test suite in parallel by specifying <code>-jN</code> when invoking the <code>prove</code> utility.
 
-Some parts of the test suite requires standard modules [[NginxHttpProxyModule|proxy]], [[NginxHttpRewriteModule|rewrite]] and [[NginxHttpSsiModule|SSI]] to be enabled as well when building Nginx.

-    Nginx and by leveraging Nginx subrequests, allows the integration of the

+    This module embeds Lua, via the standard Lua interpreter or LuaJIT 2.0
+    (<http://luajit.org/luajit.html>), into Nginx and by leveraging Nginx's
+    subrequests, allows the integration of the powerful Lua threads (Lua
+    coroutines) into the Nginx event model.
 
     Unlike Apache's mod_lua
     (<http://httpd.apache.org/docs/2.3/mod/mod_lua.html>) and Lighttpd's
     mod_magnet (<http://redmine.lighttpd.net/wiki/1/Docs:ModMagnet>), Lua
     code executed using this module can be *100% non-blocking* on network
-    traffic as long as either of the ngx.location.capture or
-    ngx.location.capture_multi interfaces are used to handle requests to
-    upstream services such as mysql, postgresql, memcached, redis, or
-    upstream http web services. (see [[HttpDrizzleModule]], ngx_postgres

-    [[HttpRedis2Module]] and [[HttpProxyModule]] modules for details).
+    traffic as long as the Nginx API for Lua provided by this module is used
+    to handle requests to upstream services such as MySQL, PostgreSQL,
+    Memcached, Redis, or upstream HTTP web services.
+
+    At least the following Lua libraries and Nginx modules can be used with
+    this ngx_lua module:
+
+    *   lua-resty-memcached
+        (<https://github.com/agentzh/lua-resty-memcached>)
+
+    *   lua-resty-mysql (<https://github.com/agentzh/lua-resty-mysql>)
+

+    Almost all the Nginx modules can be used with this ngx_lua module by
+    means of ngx.location.capture or ngx.location.capture_multi but it is
+    recommended to use those "lua-resty-*" libraries instead of creating
+    subrequests to access the Nginx upstream modules because the former is
+    usually much more flexible and memory-efficient.
 
     The Lua interpreter or LuaJIT instance is shared across all the requests
     in a single nginx worker process but request contexts are segregated

+    Runs the Lua code specified by the argument "<lua-script-str>" on the
+    global Lua VM level when the Nginx master process (if any) is loading
+    the Nginx config file.
+
+    When Nginx receives the "HUP" signal and starts reloading the config
+    file, the Lua VM will also be re-created and "init_by_lua" will run
+    again on the new Lua VM.
+
+    Usually you can register (true) Lua global variables or pre-load Lua
+    modules at server start-up by means of this hook. Here is an example for
+    pre-loading Lua modules:
+
+        init_by_lua 'require "cjson"';
+
+        server {
+            location = /api {
+                content_by_lua '
+                    ngx.say(cjson.encode({dog = 5, cat = 6}))
+                ';
+            }
+        }
+
+    You can also initialize the lua_shared_dict shm storage at this phase.
+    Here is an example for this:
+
+        lua_shared_dict dogs 1m;
+
+        init_by_lua '
+            local dogs = ngx.shared.dogs;
+            dogs:set("Tom", 56)
+        ';
+
+        server {
+            location = /api {
+                content_by_lua '
+                    local dogs = ngx.shared.dogs;
+                    ngx.say(dogs:get("Tom"))
+                ';
+            }
+        }
+
+    But note that, the lua_shared_dict's shm storage will not be cleared
+    through a config reload (via the "HUP" signal, for example). So if you
+    do *not* want to re-initialize the shm storage in your "init_by_lua"
+    code in this case, then you just need to set a custom flag in the shm
+    storage and always check the flag in your "init_by_lua" code.
+
+    Because the Lua code in this context runs before Nginx forks its worker
+    processes (if any), data or code loaded here will enjoy the
+    Copy-on-write (COW) (<http://en.wikipedia.org/wiki/Copy-on-write>)
+    feature provided by many operating systems among all the worker
+    processes, thus saving a lot of memory.
+
+    Only a small set of the Nginx API for Lua is supported in this context:
+
+    *   Logging APIs: ngx.log and print,
+
+    *   Shared Dictionary API: ngx.shared.DICT.
+
+    More Nginx APIs for Lua may be supported in this context upon future
+    user requests.
+
+    Basically you can safely use Lua libraries that do blocking I/O in this
+    very context because blocking the master process during server start-up
+    is completely okay. Even the Nginx core does blocking I/O (at least on
+    resolving upstream's host names) at the configure-loading phase.
+
+    You should be very careful about potential security vulnerabilities in
+    your Lua code registered in this context because the Nginx master
+    process is often run under the "root" account.

+    syntax: *body_filter_by_lua <lua-script-str>*
+
+    context: *http, server, location, location if*
+
+    phase: *output-body-filter*
+
+    Uses Lua code specified in "<lua-script-str>" to define an output body
+    filter.
+
+    The input data chunk is passed via ngx.arg[1] (as a Lua string value)
+    and the "eof" flag indicating the end of the response body data stream
+    is passed via ngx.arg[2] (as a Lua boolean value).
+
+    Behind the scene, the "eof" flag is just the "last_buf" flag of the
+    nginx chain link buffers. And in the context of an Nginx subrequest,
+    there is no "eof" flag at all, due to the underlying limitation in the
+    Nginx core.
+
+    The output data stream can be aborted immediately by running the
+    following Lua statement:
+
+        return ngx.ERROR
+
+    This will truncate the response body and usually result in incomplete
+    and also invalid responses.
+
+    The Lua code can pass its own modified version of the input data chunk
+    to the downstream Nginx output body filters by overriding ngx.arg[1]
+    with a Lua string or a Lua table of strings. For example, to transform
+    all the lowercase letters in the response body, we can just write:
+
+        location / {
+            proxy_pass http://mybackend;
+            body_filter_by_lua 'ngx.arg[1] = string.upper(ngx.arg[1])';
+        }
+
+    When setting "nil" or an empty Lua string value to "ngx.arg[1]", no data
+    chunk will be passed to the downstream Nginx output filters at all.
+
+    Likewise, new "eof" flag can also be specified by setting a boolean
+    value to ngx.arg[2]. For example,
+
+        location /t {
+            echo hello world;
+            echo hiya globe;
+
+            body_filter_by_lua '
+                local chunk = ngx.arg[1]
+                if string.match(chunk, "hello") then
+                    ngx.arg[2] = true  -- new eof
+                    return
+                end
+
+                -- just throw away any remaining chunk data
+                ngx.arg[1] = nil
+            ';
+        }
+
+    Then "GET /t" will just return the output
+
+        hello world
+
+    That is, when the body filter sees a chunk containing the word "hello",
+    then it will set the "eof" flag to true immediately, resulting in
+    truncated but still valid responses.
+
+    When the Lua code may change the length of the response body, then it is
+    required to always clear out the "Content-Length" response header (if
+    any) in a header filter to enforce streaming output, as in
+
+        location /foo {
+            # fastcgi_pass/proxy_pass/...
+
+            header_filter_by_lua 'ngx.header.content_length = nil';
+            body_filter_by_lua 'ngx.arg[1] = {string.len(arg[1]), "\n"}'
+        }
+
+    Note that the following API functions are currently disabled within this
+    context:
+

+
+    *   Cosocket API functions (e.g., ngx.socket.tcp and ngx.req.socket).
+
+    Nginx output filters may be called multiple times for a single request
+    because response body may be delivered in chunks. Thus, the Lua code
+    specified by in this directive may also run multiple times in the

+
+    This directive controls whether to check for premature client connection

+
+    When this directive is turned on, the ngx_lua module will monitor the
+    premature connection close event on the downstream connections. And when
+    there is such an event, it will call the user Lua function callback
+    (registered by ngx.on_abort) or just stop and clean up all the Lua
+    "light threads" running in the current request's request handler when
+    there is no user callback function registered.
+
+    According to the current implementation, however, if the client closes
+    the connection before the Lua code finishes reading the request body
+    data via ngx.req.socket, then ngx_lua will neither stop all the running
+    "light threads" nor call the user callback (if ngx.on_abort has been
+    called). Instead, the reading operation on ngx.req.socket will just
+    return the error message "client aborted" as the second return value
+    (the first return value is surely "nil").
+
+    When TCP keepalive is disabled, it is relying on the client side to
+    close the socket gracefully (by sending a "FIN" packet or something like
+    that). For (soft) real-time web applications, it is highly recommended
+    to configure the TCP keepalive
+    (<http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/overview.html>) support in
+    your system's TCP stack implementation in order to detect "half-open"
+    TCP connections in time.
+
+    For example, on Linux, you can configure the standard listen directive
+    in your "nginx.conf" file like this:
+
+        listen 80 so_keepalive=2s:2s:8;
+
+    On FreeBSD, you can only tune the system-wide configuration for TCP
+    keepalive, for example:
+
+        # sysctl net.inet.tcp.keepintvl=2000
+        # sysctl net.inet.tcp.keepidle=2000
+
+    This directive was first introduced in the "v0.7.4" release.

-HTTP 1.0 support
-    The HTTP 1.0 protocol does not support chunked outputs and always
-    requires an explicit "Content-Length" header when the response body is
-    non-empty. So when an HTTP 1.0 request is present, This module will
-    automatically buffer all the outputs of user calls of ngx.say and
-    ngx.print and postpone sending response headers until it sees all the
-    outputs in the response body, and at that time ngx_lua can calculate the
-    total length of the body and construct a proper "Content-Length" header
-    for the HTTP 1.0 client.
-
-    Note that, common HTTP benchmark tools like "ab" and "http_load" always
-    issue HTTP 1.0 requests by default. To force "curl" to send HTTP 1.0
-    requests, use the -0 option.

-Data Sharing within an Nginx Worker
-    NOTE: This mechanism behaves differently when code cache is turned off
-    and should be considered a DIRTY TRICK. Note that backward compatibility
-    is NOT guaranteed and that there may be other undesirable consequences.
-    A new data sharing mechanism will be designed later.
+    It is intended to be compatible with the UDP API of the LuaSocket
+    (<http://w3.impa.br/~diego/software/luasocket/udp.html>) library but is
+    100% nonblocking out of the box.
 
-    To globally share data among all the requests handled by the same nginx
-    worker process, encapsulate the shared data into a Lua module, use the
-    Lua "require" builtin to import the module, and then manipulate the
-    shared data in Lua. This works because required Lua modules are loaded
-    only once and all coroutines will share the same copy of the module.
-    Note however that Lua global variables WILL NOT persist between requests
-    because of the one-coroutine-per-request isolation design.
+    This feature was first introduced in the "v0.5.7" release.

+
+    Attempts to connect a UDP socket object to a remote server or to a
+    datagram unix domain socket file. Because the datagram protocol is
+    actually connection-less, this method does not really establish a
+    "connection", but only just set the name of the remote peer for
+    subsequent read/write operations.
+
+    Both IP addresses and domain names can be specified as the "host"
+    argument. In case of domain names, this method will use Nginx core's
+    dynamic resolver to parse the domain name without blocking and it is
+    required to configure the resolver directive in the "nginx.conf" file
+    like this:
+
+        resolver 8.8.8.8;  # use Google's public DNS nameserver
+
+    If the nameserver returns multiple IP addresses for the host name, this
+    method will pick up one randomly.
+
+    In case of error, the method returns "nil" followed by a string
+    describing the error. In case of success, the method returns 1.
+
+    Here is an example for connecting to a UDP (memcached) server:
+
+        location /test {
+            resolver 8.8.8.8;
+
+            content_by_lua '

+                local ok, err = sock:setpeername("my.memcached.server.domain", 11211)
+                if not ok then
+                    ngx.say("failed to connect to memcached: ", err)
+                    return
+                end
+                ngx.say("successfully connected to memcached!")
+                sock:close()
+            ';
+        }
+
+    Connecting to a datagram unix domain socket file is also possible:
+
+        local sock = ngx.socket.udp()
+        local ok, err = sock:setpeername("unix:/tmp/some-datagram-service.sock")
+        if not ok then
+            ngx.say("failed to connect to the datagram unix domain socket: ", err)
+            return
+        end
+
+    assuming the datagram service is listening on the unix domain socket
+    file "/tmp/some-datagram-service.sock".
+
+    Calling this method on an already connected socket object will cause the
+    original connection to be closed first.

+
+    Sends data on the current UDP or datagram unix domain socket object.
+
+    In case of success, it returns 1. Otherwise, it returns "nil" and a
+    string describing the error.
+
+    The input argument "data" can either be a Lua string or a (nested) Lua
+    table holding string fragments. In case of table arguments, this method
+    will copy all the string elements piece by piece to the underlying Nginx
+    socket send buffers, which is usually optimal than doing string
+    concatenation operations on the Lua land.
+
+    This feature was first introduced in the "v0.5.7" release.
+
+  udpsock:receive
+    syntax: *data, err = udpsock:receive(size?)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Receives data from the UDP or datagram unix domain socket object with an
+    optional receive buffer size argument, "size".
+
+    This method is a synchronous operation and is 100% nonblocking.
+
+    In case of success, it returns the data received; in case of error, it
+    returns "nil" with a string describing the error.
+
+    If the "size" argument is specified, then this method will use this size
+    as the receive buffer size. But when this size is greater than 8192,
+    then 8192 will be used instead.
+
+    If no argument is specified, then the maximal buffer size, 8192 is
+    assumed.
+
+    Timeout for the reading operation is controlled by the
+    lua_socket_read_timeout config directive and the settimeout method. And
+    the latter takes priority. For example:
+
+        sock:settimeout(1000)  -- one second timeout
+        local data, err = sock:receive()
+        if not data then
+            ngx.say("failed to read a packet: ", data)
+            return
+        end
+        ngx.say("successfully read a packet: ", data)
+
+    It is important here to call the settimeout method *before* calling this
+    method.

+    in case of success and returns "nil" with a string describing the error

+    connections) will be closed when the socket object is released by the

+    Attempts to connect a TCP socket object to a remote server or to a

+
+    Before actually resolving the host name and connecting to the remote

+    idle connections created by previous calls of this method (or the
+    ngx.socket.connect function).
+
+    Both IP addresses and domain names can be specified as the "host"
+    argument. In case of domain names, this method will use Nginx core's

+    Sends data without blocking on the current TCP or Unix Domain Socket
+    connection.
+
+    This method is a synchronous operation that will not return until *all*
+    the data has been flushed into the system socket send buffer or an error
+    occurs.
+
+    In case of success, it returns the total number of bytes that have been
+    sent. Otherwise, it returns "nil" and a string describing the error.
+
+    The input argument "data" can either be a Lua string or a (nested) Lua
+    table holding string fragments. In case of table arguments, this method
+    will copy all the string elements piece by piece to the underlying Nginx
+    socket send buffers, which is usually optimal than doing string
+    concatenation operations on the Lua land.
+
+    Timeout for the sending operation is controlled by the
+    lua_socket_send_timeout config directive and the settimeout method. And
+    the latter takes priority. For example:
+
+        sock:settimeout(1000)  -- one second timeout
+        local bytes, err = sock:send(request)
+
+    It is important here to call the settimeout method *before* calling this
+    method.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:receive
+    syntax: *data, err, partial = tcpsock:receive(size)*
+
+    syntax: *data, err, partial = tcpsock:receive(pattern?)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Receives data from the connected socket according to the reading pattern
+    or size.
+
+    This method is a synchronous operation just like the send method and is
+    100% nonblocking.
+
+    In case of success, it returns the data received; in case of error, it
+    returns "nil" with a string describing the error and the partial data
+    received so far.
+
+    If a number-like argument is specified (including strings that look like
+    numbers), then it is interpreted as a size. This method will not return
+    until it reads exactly this size of data or an error occurs.
+
+    If a non-number-like string argument is specified, then it is
+    interpreted as a "pattern". The following patterns are supported:
+
+    *   '*a': reads from the socket until the connection is closed. No
+        end-of-line translation is performed;
+
+    *   '*l': reads a line of text from the socket. The line is terminated
+        by a "Line Feed" (LF) character (ASCII 10), optionally preceded by a
+        "Carriage Return" (CR) character (ASCII 13). The CR and LF
+        characters are not included in the returned line. In fact, all CR
+        characters are ignored by the pattern.
+
+    If no argument is specified, then it is assumed to be the pattern '*l',
+    that is, the line reading pattern.
+
+    Timeout for the reading operation is controlled by the
+    lua_socket_read_timeout config directive and the settimeout method. And
+    the latter takes priority. For example:
+
+        sock:settimeout(1000)  -- one second timeout
+        local line, err, partial = sock:receive()
+        if not line then
+            ngx.say("failed to read a line: ", err)
+            return
+        end
+        ngx.say("successfully read a line: ", line)
+
+    It is important here to call the settimeout method *before* calling this
+    method.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:receiveuntil
+    syntax: *iterator = tcpsock:receiveuntil(pattern, options?)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    This method returns an iterator Lua function that can be called to read
+    the data stream until it sees the specified pattern or an error occurs.
+
+    Here is an example for using this method to read a data stream with the
+    boundary sequence "--abcedhb":
+
+        local reader = sock:receiveuntil("\r\n--abcedhb")
+        local data, err, partial = reader()
+        if not data then
+            ngx.say("failed to read the data stream: ", err)
+        end
+        ngx.say("read the data stream: ", data)
+
+    When called without any argument, the iterator function returns the
+    received data right *before* the specified pattern string in the
+    incoming data stream. So for the example above, if the incoming data
+    stream is 'hello, world! -agentzh\r\n--abcedhb blah blah', then the
+    string 'hello, world! -agentzh' will be returned.
+
+    In case of error, the iterator function will return "nil" along with a
+    string describing the error and the partial data bytes that have been
+    read so far.
+
+    The iterator function can be called multiple times and can be mixed
+    safely with other cosocket method calls or other iterator function
+    calls.
+
+    The iterator function behaves differently (i.e., like a real iterator)
+    when it is called with a "size" argument. That is, it will read that
+    "size" of data on each invocation and will return "nil" at the last
+    invocation (either sees the boundary pattern or meets an error). For the
+    last successful invocation of the iterator function, the "err" return
+    value will be "nil" too. The iterator function will be reset after the
+    last successful invocation that returns "nil" data and "nil" error.
+    Consider the following example:
+
+        local reader = sock:receiveuntil("\r\n--abcedhb")
+
+        while true then
+            local data, err, partial = reader(4)
+            if not data then
+                if err then
+                    ngx.say("failed to read the data stream: ", err)
+                    break
+                end
+
+                ngx.say("read done")
+                break
+            end
+            ngx.say("read chunk: [", data, "]")
+        end
+
+    Then for the incoming data stream 'hello, world! -agentzh\r\n--abcedhb
+    blah blah', we shall get the following output from the sample code
+    above:
+
+        read chunk: [hell]
+        read chunk: [o, w]
+        read chunk: [orld]
+        read chunk: [! -a]
+        read chunk: [gent]
+        read chunk: [zh]
+        read done
+
+    Note that, the actual data returned *might* be a little longer than the
+    size limit specified by the "size" argument when the boundary pattern
+    has ambiguity for streaming parsing. Near the boundary of the data
+    stream, the data string actually returned could also be shorter than the
+    size limit.
+
+    Timeout for the iterator function's reading operation is controlled by
+    the lua_socket_read_timeout config directive and the settimeout method.
+    And the latter takes priority. For example:
+
+        local readline = sock:receiveuntil("\r\n")
+
+        sock:settimeout(1000)  -- one second timeout
+        line, err, partial = readline()
+        if not line then
+            ngx.say("failed to read a line: ", err)
+            return
+        end
+        ngx.say("successfully read a line: ", line)
+
+    It is important here to call the settimeout method *before* calling the
+    iterator function (note that the "receiveuntil" call is irrelevant
+    here).
+
+    As from the "v0.5.1" release, this method also takes an optional
+    "options" table argument to control the behavior. The following options
+    are supported:
+
+    *   "inclusive"
+
+    The "inclusive" takes a boolean value to control whether to include the
+    pattern string in the returned data string. Default to "false". For
+    example,
+
+        local reader = tcpsock:receiveuntil("_END_", { inclusive = true })
+        local data = reader()
+        ngx.say(data)
+
+    Then for the input data stream "hello world _END_ blah blah blah", then
+    the example above will output "hello world _END_", including the pattern
+    string "_END_" itself.
+
+    This method was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:close
+    syntax: *ok, err = tcpsock:close()*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Closes the current TCP or stream unix domain socket. It returns the 1 in
+    case of success and returns "nil" with a string describing the error
+    otherwise.
+
+    Note that there is no need to call this method on socket objects that
+    have invoked the setkeepalive method because the socket object is
+    already closed (and the current connection is saved into the built-in
+    connection pool).
+
+    Socket objects that have not invoked this method (and associated
+    connections) will be closed when the socket object is released by the
+    Lua GC (Garbage Collector) or the current client HTTP request finishes
+    processing.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:settimeout
+    syntax: *tcpsock:settimeout(time)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Set the timeout value in milliseconds for subsequent socket operations
+    (connect, receive, and iterators returned from receiveuntil).
+
+    Settings done by this method takes priority over those config
+    directives, i.e., lua_socket_connect_timeout, lua_socket_send_timeout,
+    and lua_socket_read_timeout.
+
+    Note that this method does *not* affect the lua_socket_keepalive_timeout
+    setting; the "timeout" argument to the setkeepalive method should be
+    used for this purpose instead.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:setoption
+    syntax: *tcpsock:setoption(option, value?)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    This function is added for LuaSocket
+    (<http://w3.impa.br/~diego/software/luasocket/tcp.html>) API
+    compatibility and does nothing for now. Its functionality will be
+    implemented in future.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:setkeepalive
+    syntax: *ok, err = tcpsock:setkeepalive(timeout?, size?)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Puts the current socket's connection immediately into the cosocket
+    built-in connection pool and keep it alive until other connect method
+    calls request it or the associated maximal idle timeout is expired.
+
+    The first optional argument, "timeout", can be used to specify the
+    maximal idle timeout (in milliseconds) for the current connection. If
+    omitted, the default setting in the lua_socket_keepalive_timeout config
+    directive will be used. If the 0 value is given, then the timeout
+    interval is unlimited.
+
+    The second optional argument, "size", can be used to specify the maximal
+    number of connections allowed in the connection pool for the current
+    server (i.e., the current host-port pair or the unix domain socket file
+    path). Note that the size of the connection pool cannot be changed once
+    the pool is created. When this argument is omitted, the default setting
+    in the lua_socket_pool_size config directive will be used.
+
+    When the connection pool exceeds the available size limit, the least
+    recently used (idle) connection already in the pool will be closed to
+    make room for the current connection.
+
+    Note that the cosocket connection pool is per Nginx worker process
+    rather than per Nginx server instance, so the size limit specified here
+    also applies to every single Nginx worker process.
+
+    Idle connections in the pool will be monitored for any exceptional
+    events like connection abortion or unexpected incoming data on the line,
+    in which cases the connection in question will be closed and removed
+    from the pool.
+
+    In case of success, this method returns 1; otherwise, it returns "nil"
+    and a string describing the error.
+
+    This method also makes the current cosocket object enter the "closed"
+    state, so there is no need to manually call the close method on it
+    afterwards.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  tcpsock:getreusedtimes
+    syntax: *count, err = tcpsock:getreusedtimes()*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    This method returns the (successfully) reused times for the current
+    connection. In case of error, it returns "nil" and a string describing
+    the error.
+
+    If the current connection does not come from the built-in connection
+    pool, then this method always returns 0, that is, the connection has
+    never been reused (yet). If the connection comes from the connection
+    pool, then the return value is always non-zero. So this method can also
+    be used to determine if the current connection comes from the pool.
+
+    This feature was first introduced in the "v0.5.0rc1" release.
+
+  ngx.socket.connect
+    syntax: *tcpsock, err = ngx.socket.connect(host, port)*
+
+    syntax: *tcpsock, err =
+    ngx.socket.connect("unix:/path/to/unix-domain.socket")*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    This function is a shortcut for combining ngx.socket.tcp() and the
+    connect() method call in a single operation. It is actually implemented
+    like this:
+
+        local sock = ngx.socket.tcp()
+        local ok, err = sock:connect(...)
+        if not ok then
+            return nil, err
+        end
+        return sock
+
+    There is no way to use the settimeout method to specify connecting
+    timeout for this method and the lua_socket_connect_timeout directive
+    must be set at configure time instead.
+
+    This feature was first introduced in the "v0.5.0rc1" release.

+
+    Retrieves the current running phase name. Possible return values are
+
+    *   "init" for the context of init_by_lua or init_by_lua_file. =item *

+    syntax: *co = ngx.thread.spawn(func, arg1, arg2, ...)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Spawns a new user "light thread" with the Lua function "func" as well as
+    those optional arguments "arg1", "arg2", and etc. Returns a Lua thread
+    (or Lua coroutine) object represents this "light thread".
+
+    "Light threads" are just a special kind of Lua coroutines that are
+    scheduled by the ngx_lua module.
+
+    Before "ngx.thread.spawn" returns, the "func" will be called with those
+    optional arguments until it returns, aborts with an error, or gets
+    yielded due to I/O operations via the Nginx API for Lua (like
+    <tcpsock:receive|/"tcpsock:receive">).
+
+    After "ngx.thread.spawn" returns, the newly-created "light thread" will
+    keep running asynchronously usually at various I/O events.
+
+    All the Lua code chunks running by rewrite_by_lua, access_by_lua, and
+    content_by_lua are in a boilerplate "light thread" created automatically
+    by ngx_lua. Such boilerplate "light thread" are also called "entry
+    threads".
+
+    By default, the corresponding Nginx handler (e.g., rewrite_by_lua
+    handler) will not terminate until
+
+    1.  both the "entry thread" and all the user "light threads" terminates,
+
+    2.  a "light thread" (either the "entry thread" or a user "light thread"
+        aborts by calling ngx.exit, ngx.exec, ngx.redirect, or
+        ngx.req.set_uri(uri, true), or
+
+    3.  the "entry thread" terminates with a Lua error.
+
+    When the user "light thread" terminates with a Lua error, however, it
+    will not abort other running "light threads" like the "entry thread"
+    does.
+
+    Due to the limitation in the Nginx subrequest model, it is not allowed
+    to abort a running Nginx subrequest in general. So it is also prohibited
+    to abort a running "light thread" that is pending on one ore more Nginx
+    subrequests. You must call ngx.thread.wait to wait for those "light
+    thread" to terminate before quitting the "world". A notable exception
+    here is that you can abort pending subrequests by calling ngx.exit with
+    and only with the status code "ngx.ERROR" (-1), 408, 444, or 499.
+
+    The "light threads" are not scheduled in a pre-emptive way. In other
+    words, no time-slicing is performed automatically. A "light thread" will
+    keep running exclusively on the CPU until
+
+    1.  a (nonblocking) I/O operation cannot be completed in a single run,
+
+    2.  it calls coroutine.yield to actively give up execution, or
+
+    3.  it is aborted by a Lua error or an invocation of ngx.exit, ngx.exec,
+        ngx.redirect, or ngx.req.set_uri(uri, true).
+
+    For the first two cases, the "light thread" will usually be resumed
+    later by the ngx_lua scheduler unless a "stop-the-world" event happens.
+
+    User "light threads" can create "light threads" themselves and normal
+    user coroutiens created by coroutine.create can also create "light
+    threads". The coroutine (be it a normal Lua coroutine or a "light
+    thread") that directly spawns the "light thread" is called the "parent
+    coroutine" for the "light thread" newly spawned.
+
+    The "parent coroutine" can call ngx.thread.wait to wait on the
+    termination of its child "light thread".
+
+    You can call coroutine.status() and coroutine.yield() on the "light
+    thread" coroutines.
+
+    The status of the "light thread" coroutine can be "zombie" if
+
+    1.  the current "light thread" already terminates (either successfully
+        or with an error),
+
+    2.  its parent coroutine is still alive, and
+
+    3.  its parent coroutine is not waiting on it with ngx.thread.wait.
+
+    The following example demonstrates the use of coroutine.yield() in the
+    "light thread" coroutines to do manual time-slicing:
+
+        local yield = coroutine.yield
+
+        function f()
+            local self = coroutine.running()
+            ngx.say("f 1")
+            yield(self)
+            ngx.say("f 2")
+            yield(self)
+            ngx.say("f 3")
+        end
+
+        local self = coroutine.running()
+        ngx.say("0")
+        yield(self)
+
+        ngx.say("1")
+        ngx.thread.spawn(f)
+
+        ngx.say("2")
+        yield(self)
+
+        ngx.say("3")
+        yield(self)
+
+        ngx.say("4")
+
+    Then it will generate the output
+
+        0
+        1

+    "Light threads" are mostly useful for doing concurrent upstream requests
+    in a single Nginx request handler, kinda like a generalized version of
+    ngx.location.capture_multi that can work with all the Nginx API for Lua.
+    The following example demonstrates parallel requests to MySQL,
+    Memcached, and upstream HTTP services in a single Lua handler, and
+    outputting the results in the order that they actually return (very much
+    like the Facebook BigPipe model):
+
+        -- query mysql, memcached, and a remote http service at the same time,
+        -- output the results in the order that they
+        -- actually return the results.
+
+        local mysql = require "resty.mysql"
+        local memcached = require "resty.memcached"
+
+        local function query_mysql()
+            local db = mysql:new()
+            db:connect{
+                        host = "127.0.0.1",

+                        password = "mypass"
+                      }
+            local res, err, errno, sqlstate =

+            db:set_keepalive(0, 100)

+        end
+
+        local function query_memcached()
+            local memc = memcached:new()
+            memc:connect("127.0.0.1", 11211)

+        ngx.thread.spawn(query_memcached)  -- create thread 2

+
+    This API was first enabled in the "v0.7.0" release.
+
+  ngx.thread.wait
+    syntax: *ok, res1, res2, ... = ngx.thread.wait(thread1, thread2, ...)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Waits on one or more child "light threads" and returns the results of
+    the first "light thread" that terminates (either successfully or with an
+    error).
+
+    The arguments "thread1", "thread2", and etc are the Lua thread objects
+    returned by earlier calls of ngx.thread.spawn.
+
+    The return values have exactly the same meaning as coroutine.resume,
+    that is, the first value returned is a boolean value indicating whether
+    the "light thread" terminates successfully or not, and subsequent values
+    returned are the return values of the user Lua function that was used to
+    spawn the "light thread" (in case of success) or the error object (in
+    case of failure).
+
+    Only the direct "parent coroutine" can wait on its child "light thread",
+    otherwise a Lua exception will be raised.
+
+    The following example demonstrates the use of "ngx.thread.wait" and
+    ngx.location.capture to emulate ngx.location.capture_multi:
+
+        local capture = ngx.location.capture
+        local spawn = ngx.thread.spawn
+        local wait = ngx.thread.wait
+        local say = ngx.say
+
+        local function fetch(uri)
+            return capture(uri)
+        end
+
+        local threads = {
+            spawn(fetch, "/foo"),
+            spawn(fetch, "/bar"),
+            spawn(fetch, "/baz")
+        }
+
+        for i = 1, #threads do
+            local ok, res = wait(threads[i])
+            if not ok then
+                say(i, ": failed to run: ", res)
+            else
+                say(i, ": status: ", res.status)
+                say(i, ": body: ", res.body)
+            end
+        end
+
+    Here it essentially implements the "wait all" model.
+
+    And below is an example demonstrating the "wait any" model:
+
+        function f()
+            ngx.sleep(0.2)
+            ngx.say("f: hello")
+            return "f done"
+        end
+
+        function g()
+            ngx.sleep(0.1)
+            ngx.say("g: hello")
+            return "g done"
+        end
+
+        local tf, err = ngx.thread.spawn(f)
+        if not tf then
+            ngx.say("failed to spawn thread f: ", err)
+            return
+        end
+
+        ngx.say("f thread created: ", coroutine.status(tf))
+
+        local tg, err = ngx.thread.spawn(g)
+        if not tg then
+            ngx.say("failed to spawn thread g: ", err)
+            return
+        end
+
+        ngx.say("g thread created: ", coroutine.status(tg))
+
+        ok, res = ngx.thread.wait(tf, tg)
+        if not ok then
+            ngx.say("failed to wait: ", res)
+            return
+        end
+
+        ngx.say("res: ", res)
+
+        -- stop the "world", aborting other running threads
+        ngx.exit(ngx.OK)
+
+    And it will generate the following output:
+
+        f thread created: running
+        g thread created: running
+        g: hello
+        res: g done
+
+    This API was first enabled in the "v0.7.0" release.
+
+  ngx.on_abort
+    syntax: *ok, err = ngx.on_abort(callback)*
+
+    context: *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+    Registers a user Lua function as the callback which gets called
+    automatically when the client closes the (downstream) connection
+    prematurely.
+
+    Returns 1 if the callback is registered successfully or returns "nil"
+    and a string describing the error otherwise.
+
+    All the Nginx API for Lua can be used in the callback function because
+    the function is run in a special "light thread", just as those "light
+    threads" created by ngx.thread.spawn.
+
+    The callback function can decide what to do with the client abortion
+    event all by itself. For example, it can simply ignore the event by
+    doing nothing and the current Lua request handler will continue
+    executing without interruptions. And the callback function can also
+    decide to terminate everything by calling ngx.exit, for example,
+
+        local function my_cleanup()
+            -- custom cleanup work goes here, like cancelling a pending DB transaction
+
+            -- now abort all the "light threads" running in the current request handler
+            ngx.exit(499)
+        end
+
+        local ok, err = ngx.on_abort(my_cleanup)
+        if not ok then
+            ngx.log(ngx.ERR, "failed to register the on_abort callback: ", err)
+            ngx.exit(500)
+        end
+
+    When lua_check_client_abort is set to "off" (which is the default), then
+    this function call will always return the error message
+    "lua_check_client_abort is off".
+
+    According to the current implementation, this function can only be
+    called once in a single request handler; subsequent calls will return
+    the error message "duplicate call".
+
+    This API was first introduced in the "v0.7.4" release.
+
+    See also lua_check_client_abort.
+
+  ndk.set_var.DIRECTIVE
+    syntax: *res = ndk.set_var.DIRECTIVE_NAME*
+
+    context: *set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*,
+    header_filter_by_lua*, body_filter_by_lua*, log_by_lua**
+
+    This mechanism allows calling other nginx C modules' directives that are
+    implemented by Nginx Devel Kit
+    (<https://github.com/simpl/ngx_devel_kit>) (NDK)'s set_var submodule's
+    "ndk_set_var_value".
+
+    For example, the following [[HttpSetMiscModule]] directives can be
+    invoked this way:
+
+    *   set_quote_sql_str
+
+    *   set_quote_pgsql_str
+
+    *   set_quote_json_str
+
+    *   set_unescape_uri
+
+    *   set_escape_uri
+
+    *   set_encode_base32
+
+    *   set_decode_base32
+
+    *   set_encode_base64
+
+    *   set_decode_base64
+
+    *   set_encode_hex
+
+    *   set_decode_hex
+
+    *   set_sha1
+
+    *   set_md5
+
+    For instance,
+
+        local res = ndk.set_var.set_escape_uri('a/b');
+        -- now res == 'a%2fb'
+
+    Similarly, the following directives provided by
+    [[HttpEncryptedSessionModule]] can be invoked from within Lua too:
+
+    *   set_encrypt_session
+
+    *   set_decrypt_session
+
+    This feature requires the ngx_devel_kit
+    (<https://github.com/simpl/ngx_devel_kit>) module.
+
+Lua/LuaJIT bytecode support
+    As from the "v0.5.0rc32" release, all *_by_lua_file configure directives
+    (such as content_by_lua_file) support loading Lua 5.1 and LuaJIT 2.0 raw
+    bytecode files directly.
+
+    Please note that the bytecode format used by LuaJIT 2.0 is not
+    compatible with that used by the standard Lua 5.1 interpreter. So if
+    using LuaJIT 2.0 with ngx_lua, LuaJIT compatible bytecode files must be
+    generated as shown:
+
+        /path/to/luajit/bin/luajit -b /path/to/input_file.lua /path/to/output_file.luac
+
+    The "-bg" option can be used to include debug information in the LuaJIT
+    bytecode file:
+
+        /path/to/luajit/bin/luajit -bg /path/to/input_file.lua /path/to/output_file.luac
+
+    Please refer to the official LuaJIT documentation on the "-b" option for
+    more details:
+
+    http://luajit.org/running.html#opt_b
+
+    Similarly, if using the standard Lua 5.1 interpreter with ngx_lua, Lua
+    compatible bytecode files must be generated using the "luac" commandline
+    utility as shown:
+
+        luac -o /path/to/output_file.luac /path/to/input_file.lua
+
+    Unlike as with LuaJIT, debug information is included in standard Lua 5.1
+    bytecode files by default. This can be striped out by specifying the
+    "-s" option as shown:
+
+        luac -s -o /path/to/output_file.luac /path/to/input_file.lua
+
+    Attempts to load standard Lua 5.1 bytecode files into ngx_lua instances
+    linked to LuaJIT 2.0 or vice versa, will result in an error message,
+    such as that below, being logged into the Nginx "error.log" file:
+
+        [error] 13909#0: *1 failed to load Lua inlined code: bad byte-code header in /path/to/test_file.luac
+
+    Loading bytecode files via the Lua primitives like "require" and
+    "dofile" should always work as expected.
+
+HTTP 1.0 support
+    The HTTP 1.0 protocol does not support chunked output and requires an
+    explicit "Content-Length" header when the response body is not empty in
+    order to support the HTTP 1.0 keep-alive. So when a HTTP 1.0 request is
+    made and the lua_http10_buffering directive is turned "on", ngx_lua will
+    buffer the output of ngx.say and ngx.print calls and also postpone
+    sending response headers until all the response body output is received.
+    At that time ngx_lua can calculate the total length of the body and
+    construct a proper "Content-Length" header to return to the HTTP 1.0
+    client. If the "Content-Length" response header is set in the running
+    Lua code, however, this buffering will be disabled even if the
+    lua_http10_buffering directive is turned "on".
+
+    For large streaming output responses, it is important to disable the
+    lua_http10_buffering directive to minimise memory usage.
+
+    Note that common HTTP benchmark tools such as "ab" and "http_load" issue
+    HTTP 1.0 requests by default. To force "curl" to send HTTP 1.0 requests,
+    use the -0 option.
+
+Data Sharing within an Nginx Worker
+    To globally share data among all the requests handled by the same nginx
+    worker process, encapsulate the shared data into a Lua module, use the
+    Lua "require" builtin to import the module, and then manipulate the
+    shared data in Lua. This works because required Lua modules are loaded
+    only once and all coroutines will share the same copy of the module.
+    Note however that Lua global variables WILL NOT persist between requests
+    because of the one-coroutine-per-request isolation design.
+
+    Here is a complete small example:
+
+        -- mydata.lua
+        module(...)
+
+        local data = {
+            dog = 3,
+            cat = 4,
+            pig = 5,
+        }
+
+        function get_age(name)
             return data[name]
         end
 
     and then accessing it from "nginx.conf":
 
         location /lua {
-            content_lua_by_lua '
-                local mydata = require("mydata")

-Changes
-  v0.4.1
-    1 February, 2012
-
-    *   bugfix: ngx.exit, ngx.redirect, ngx.exec, and ngx.req.set_uri(uri,
-        true) could return (they should never return as per the
-        documentation). this bug had appeared in ngx_lua v0.3.1rc4 and
-        ngx_openresty 1.0.6.13. thanks @cyberty (<http://weibo.com/cyberty>)
-        for reporting it.
-
-    *   bugfix: "ngx_http_lua_header_filter_init" was called with an
-        argument which actually accepts none. this could cause compilation
-        errors at least with gcc 4.3.4 as reported in github issue #80
-        (<http://github.com/chaoslawful/lua-nginx-module/issues/80>). thanks
-        bigplum (Simon).
-
-    *   bugfix: fixed all the warnings from the clang static analyzer.
-
-    *   feature: allow use of the "DDEBUG" macro from the outside (via the
-        "-D DDEBUG=1" C compiler opton).
-
-  v0.4.0
-    11 January, 2012
-
-    *   bugfix: fixed a bug when the both the main request and the
-        subrequest are POST requests with a body: we should not forward the
-        main request's "Content-Length" headers to the user subrequests.
-        thanks 朱峰.
-
-    *   feature: implemented the API for reading response headers from
-        within Lua: "value = ngx.header.HEADER", see ngx.header.HEADER.
-
-    *   bugfix: fixed a bug when setting a multi-value response header to a
-        single value (via writing to ngx.header.HEADER): the single value
-        will be repeated on each old value.
-
-    *   bugfix: fixed an issue in ngx.redirect, ngx.exit, and ngx.exec:
-        these function calls would be intercepted by Lua "pcall"/"xpcall"
-        because they used Lua exceptions; now they use Lua yield just as
-        ngx.location.capture. thanks @hugozhu for reporting this.
-
-    *   feature: now we also return the "Last-Modified" header (if any) for
-        the subrequest response object. thanks @cyberty and sexybabes.
-
-    *   feature: now ngx.exec supports Lua table as the second args argument
-        value. thanks sexybabes.
-
-    *   feature: implemented the ngx.headers_sent API to check if response
-        headers are sent (by ngx_lua). thanks @hugozhu.
-
-    *   feature: exposes the CRC-32 API of the Nginx core to the Lua land,
-        in the form of the ngx.crc32_short and ngx.crc32_long methods.
-        thanks @Lance.
-
-    *   feature: now for HTTP 1.0 requests, we disable the automatic full
-        buffering mode if the user sets the "Content-Length" response header
-        before sending out the headers. this allows streaming output for
-        HTTP 1.0 requests if the content length can be calculated
-        beforehand. thanks 李子义.
-
-    *   bugfix: now we properly support setting the "Cache-Control" response
-        header via the ngx.header.HEADER interface.
-
-    *   bugfix: no longer set header hash to 1. use the "ngx_hash_key_lc"
-        instead.
-
-    *   bugfix: calling ngx.exec to jump to a named location did not clear
-        the context object of LuaNginxModule properly and might cause evil
-        problems. thanks Nginx User.
-
-    *   bugfix: now we explicitly clear all the modules' contexts before
-        dump to named location with ngx.exec.
-
-    *   feature: implemented ngx.req.set_uri and ngx.req.set_uri_args to
-        emulate [[HttpRewriteModule]]'s rewrite directive. thanks Vladimir
-        Protasov (utros) and Nginx User.
-
-    *   bugfix: now we skip rewrite phase Lua handlers altogether if
-        [[HttpRewriteModule]]'s rewrite directive issue a location re-lookup
-        by changing URIs (but not including "rewrite ... break"). thanks
-        Nginx User.
-
-    *   feature: added constant "ngx.HTTP_METHOD_NOT_IMPLEMENTED (501)".
-        thanks Nginx User.
-
-    *   feature: added new Lua functions ngx.req.read_body,
-        ngx.req.discard_body, ngx.req.get_body_data, and
-        ngx.req.get_body_file. thanks Tzury Bar Yochay for funding the
-        development work.
-
-    *   bugfix: fixed hanging issues when using ngx.exec within
-        rewrite_by_lua and access_by_lua. thanks Nginx User for reporting
-        it.
-
-    *   feature: added new Lua API ngx.req.set_body_file. thanks Tzury Bar
-        Yochay for funding the development work.
-
-    *   feature: added new Lua API ngx.req.set_body_data. thanks Tzury Bar
-        Yochay for funding the development work.
-
-    *   bugfix: lua_need_request_body should not skip requests with methods
-        other than "POST" and "PUT". thanks Nginx User.
-
-    *   bugfix: no longer free request body buffers that are not allocated
-        by ourselves.
-
-    *   bugfix: now we allow setting ngx.var.VARIABLE to nil.
-
-    *   feature: added new directive lua_shared_dict.
-
-    *   feature: added Lua API for the shm-based dictionary, see
-        ngx.shared.DICT.
-
-    *   bugfix: fixed spots of -Werror=unused-but-set-variable warning
-        issued by gcc 4.6.0.
+    If the standard Lua 5.1 interpreter is required however, run the
+    following command to install it from the Ubuntu repository:
 
-    *   bugfix: ndk.set_var.DIRECTIVE had a memory issue and might pass
-        empty argument values to the directive being called. thanks
-        dannynoonan.
+    apt-get install -y lua5.1 liblua5.1-0 liblua5.1-0-dev
 
-    *   feature: added the "ctx" option to ngx.location.capture: you can now
-        specify a custom Lua table to pass to the subrequest as its ngx.ctx.
-        thanks @hugozhu.
+    Everything should be installed correctly, except for one small tweak.
 
-    *   feature: added the ngx.encode_args method to encode a Lua code to a
-        URI query string. thanks 郭颖 (0597虾).
+    Library name "liblua.so" has been changed in liblua5.1 package, it only
+    comes with "liblua5.1.so", which needs to be symlinked to "/usr/lib" so
+    it could be found during the configuration process.
 
-    *   feature: ngx.location.capture and ngx.exec now supports the same Lua
-        args table format as in ngx.encode_args. thanks 郭颖 (0597虾).
+    ln -s /usr/lib/x86_64-linux-gnu/liblua5.1.so /usr/lib/liblua.so
 
-    *   bugfix: "Cache-Control" header modification might introduce empty
-        value headers when using with the standard HttpHeadersModule.
+Community

-    *   docs: documented the long-existent ngx.md5 and ngx.md5_bin APIs.
-
-    *   docs: massive documentation improvements. thanks Nginx User.
-
-    *   feature: added new regex options "j" and "d" to ngx.re.match,
-        ngx.re.gmatch, ngx.re.sub, and ngx.re.gsub so as to enable the PCRE
-        JIT mode and DFA mode, respectively. thanks @姜大炮 for providing the
-        patch.
-
-    *   feature: added options "copy_all_vars" and "vars" to
-        ngx.location.capture and ngx.location.capture_multi. thanks Marcus
-        Clyne for the patch.
-
-    *   feature: added new Lua API ngx.now to return the current time
-        (including the milliseconds part as the decimal part). thanks 林青.
-
-    *   feature: added new Lua API ngx.update_time to forcibly updating
-        Nginx's time cache.
-
-    *   feature: added "wait" boolean argument to ngx.flush to support
-        synchronous flushing: "ngx.flush(true)" will not return until all
-        the data has been flushed into the system send buffer or the send
-        timeout has expired.
-
-    *   bugfix: now we check timed out downstream connections in our write
-        event handler.
-
-    *   feature: added constant "ngx.HTTP_GATEWAY_TIMEOUT (504)" per Fry-kun
-        in github issue #73
-        (<https://github.com/chaoslawful/lua-nginx-module/issues/73>).
-
-    *   bugfix: ngx.var.VARIABLE did not evaluate to "nil" when the Nginx
-        variable's "valid" flag is 0.
-
-    *   bugfix: there were various places where we did not check the pointer
-        returned by the memory allocator.
-
-    *   bugfix: ngx.req.set_header and ngx.req.clear_header did not handle
-        the "Accept-Encoding" request headers properly. thanks 天街夜色.
-
-    *   bugfix: ngx.req.set_header might cause invalid memory reads because
-        Nginx request header values must be "NULL" terminated. thanks Maxim
-        Dounin.
-
-    *   bugfix: removing builtin headers via ngx.req.clear_header and its
-        equivalent in huge request headers with 20+ entries could result in
-        data loss. thanks Chris Dumoulin.
-
-    *   bugfix: ngx.req.get_uri_args and ngx.req.get_post_args now only
-        parse up to 100 arguments by default. but one can specify the
-        optional argument to these two methods to specify a custom maximum
-        number of args. thanks Tzury Bar Yochay for reporting this.

+TODO
+  Short Term
+    *   review and apply Brian Akin's patch for the new directive
+        "lua_socket_log_errors".
 
-    *   now we add the "ngx" and "ndk" table into "package.loaded" such that
-        the user can write "local ngx = require 'ngx'" and "local ndk =
-        require 'ndk'". thanks @Lance.

-    *   added new directive lua_regex_cache_max_entries to control the upper
-        limit of the worker-process-level compiled-regex cache enabled by
-        the "o" regex option.
+    *   implement the SSL cosocket API.
 
-    *   implemented the special ngx.ctx Lua table for user programmers to
-        store per-request Lua context data for their applications. thanks
-        欧远宁 for suggesting this feature.
+    *   review and apply Jader H. Silva's patch for "ngx.re.split()".
 
-    *   now ngx.print and ngx.say allow (nested) array-like table arguments.
-        the array elements in them will be sent piece by piece. this will
-        avoid string concatenation for templating engines like ltp

-    *   implemented the ngx.req.get_post_args method for fetching
-        url-encoded POST query arguments from within Lua.
+    *   use "ngx_hash_t" to optimize the built-in header look-up process for
+        ngx.req.set_header, ngx.header.HEADER, and etc.
 
-    *   implemented the ngx.req.get_uri_args method to fetch parsed URL
-        query arguments from within Lua. thanks Bertrand Mansion (golgote).
+    *   add configure options for different strategies of handling the
+        cosocket connection exceeding in the pools.
 
-    *   added new function ngx.parse_http_time, thanks James Hurst.
+    *   add directives to run Lua codes when nginx stops.
 
-    *   now we allow Lua boolean and "nil" values in arguments to ngx.say,
-        ngx.print, ngx.log and print.
+    *   add APIs to access cookies as key/value pairs.
 
-    *   added support for user C macros "LUA_DEFAULT_PATH" and
-        "LUA_DEFAULT_CPATH". for now we can only define them in "ngx_lua"'s
-        "config" file because nginx "configure"'s "--with-cc-opt" option

+This module embeds Lua, via the standard Lua interpreter or [LuaJIT 2.0](http://luajit.org/luajit.html), into Nginx and by leveraging Nginx's subrequests, allows the integration of the powerful Lua threads (Lua coroutines) into the Nginx event model.
+
+Unlike [Apache's mod_lua](http://httpd.apache.org/docs/2.3/mod/mod_lua.html) and [Lighttpd's mod_magnet](http://redmine.lighttpd.net/wiki/1/Docs:ModMagnet), Lua code executed using this module can be *100% non-blocking* on network traffic as long as the [Nginx API for Lua](http://wiki.nginx.org/HttpLuaModule#Nginx_API_for_Lua) provided by this module is used to handle
+requests to upstream services such as MySQL, PostgreSQL, Memcached, Redis, or upstream HTTP web services.
+
+At least the following Lua libraries and Nginx modules can be used with this ngx_lua module:
+
+* [lua-resty-memcached](https://github.com/agentzh/lua-resty-memcached)
+* [lua-resty-mysql](https://github.com/agentzh/lua-resty-mysql)

(see [HttpDrizzleModule](http://wiki.nginx.org/HttpDrizzleModule), [ngx_postgres](http://github.com/FRiCKLE/ngx_postgres/), [HttpMemcModule](http://wiki.nginx.org/HttpMemcModule), [HttpRedis2Module](http://wiki.nginx.org/HttpRedis2Module) and [HttpProxyModule](http://wiki.nginx.org/HttpProxyModule) modules for details).
+Almost all the Nginx modules can be used with this ngx_lua module by means of [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) or [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi) but it is recommended to use those `lua-resty-*` libraries instead of creating subrequests to access the Nginx upstream modules because the former is usually much more flexible and memory-efficient.
 
-The Lua interpreter or LuaJIT instance is shared across all the requests in a single nginx worker process but request contexts are segregated using lightweight Lua coroutines. 
-Loaded Lua modules persist at the nginx worker process level resulting in a small memory footprint even when under heavy loads.

+init_by_lua
+-----------
+
+**syntax:** *init_by_lua &lt;lua-script-str&gt;*
+
+**context:** *http*
+
+**phase:** *loading-config*
+
+Runs the Lua code specified by the argument `<lua-script-str>` on the global Lua VM level when the Nginx master process (if any) is loading the Nginx config file.
+
+When Nginx receives the `HUP` signal and starts reloading the config file, the Lua VM will also be re-created and `init_by_lua` will run again on the new Lua VM.
+
+Usually you can register (true) Lua global variables or pre-load Lua modules at server start-up by means of this hook. Here is an example for pre-loading Lua modules:
+
+
+    init_by_lua 'require "cjson"';
+
+    server {
+        location = /api {
+            content_by_lua '
+                ngx.say(cjson.encode({dog = 5, cat = 6}))
+            ';
+        }
+    }
+
+
+You can also initialize the [lua_shared_dict](http://wiki.nginx.org/HttpLuaModule#lua_shared_dict) shm storage at this phase. Here is an example for this:
+
+
+    lua_shared_dict dogs 1m;
+
+    init_by_lua '
+        local dogs = ngx.shared.dogs;
+        dogs:set("Tom", 56)
+    ';
+
+    server {
+        location = /api {
+            content_by_lua '
+                local dogs = ngx.shared.dogs;
+                ngx.say(dogs:get("Tom"))
+            ';
+        }
+    }
+
+
+But note that, the [lua_shared_dict](http://wiki.nginx.org/HttpLuaModule#lua_shared_dict)'s shm storage will not be cleared through a config reload (via the `HUP` signal, for example). So if you do *not* want to re-initialize the shm storage in your `init_by_lua` code in this case, then you just need to set a custom flag in the shm storage and always check the flag in your `init_by_lua` code.
+
+Because the Lua code in this context runs before Nginx forks its worker processes (if any), data or code loaded here will enjoy the [Copy-on-write (COW)](http://en.wikipedia.org/wiki/Copy-on-write) feature provided by many operating systems among all the worker processes, thus saving a lot of memory.
+
+Only a small set of the [Nginx API for Lua](http://wiki.nginx.org/HttpLuaModule#Nginx_API_for_Lua) is supported in this context:
+
+* Logging APIs: [ngx.log](http://wiki.nginx.org/HttpLuaModule#ngx.log) and [print](http://wiki.nginx.org/HttpLuaModule#print),
+* Shared Dictionary API: [ngx.shared.DICT](http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT).
+
+More Nginx APIs for Lua may be supported in this context upon future user requests.
+
+Basically you can safely use Lua libraries that do blocking I/O in this very context because blocking the master process during server start-up is completely okay. Even the Nginx core does blocking I/O (at least on resolving upstream's host names) at the configure-loading phase.
+
+You should be very careful about potential security vulnerabilities in your Lua code registered in this context because the Nginx master process is often run under the `root` account.
+
+This directive was first introduced in the `v0.5.5` release.

+body_filter_by_lua
+------------------
+
+**syntax:** *body_filter_by_lua &lt;lua-script-str&gt;*
+
+**context:** *http, server, location, location if*
+
+**phase:** *output-body-filter*
+
+Uses Lua code specified in `<lua-script-str>` to define an output body filter.
+
+The input data chunk is passed via [ngx.arg](http://wiki.nginx.org/HttpLuaModule#ngx.arg)[1] (as a Lua string value) and the "eof" flag indicating the end of the response body data stream is passed via [ngx.arg](http://wiki.nginx.org/HttpLuaModule#ngx.arg)[2] (as a Lua boolean value).
+
+Behind the scene, the "eof" flag is just the `last_buf` flag of the nginx chain link buffers. And in the context of an Nginx subrequest, there is no "eof" flag at all, due to the underlying limitation in the Nginx core.
+
+The output data stream can be aborted immediately by running the following Lua statement:
+
+
+    return ngx.ERROR
+
+
+This will truncate the response body and usually result in incomplete and also invalid responses.
+
+The Lua code can pass its own modified version of the input data chunk to the downstream Nginx output body filters by overriding [ngx.arg](http://wiki.nginx.org/HttpLuaModule#ngx.arg)[1] with a Lua string or a Lua table of strings. For example, to transform all the lowercase letters in the response body, we can just write:
+
+
+    location / {
+        proxy_pass http://mybackend;
+        body_filter_by_lua 'ngx.arg[1] = string.upper(ngx.arg[1])';
+    }
+
+
+When setting `nil` or an empty Lua string value to `ngx.arg[1]`, no data chunk will be passed to the downstream Nginx output filters at all.
+
+Likewise, new "eof" flag can also be specified by setting a boolean value to [ngx.arg](http://wiki.nginx.org/HttpLuaModule#ngx.arg)[2]. For example,
+
+
+    location /t {
+        echo hello world;
+        echo hiya globe;
+
+        body_filter_by_lua '
+            local chunk = ngx.arg[1]
+            if string.match(chunk, "hello") then
+                ngx.arg[2] = true  -- new eof
+                return
+            end
+
+            -- just throw away any remaining chunk data
+            ngx.arg[1] = nil
+        ';
+    }
+
+
+Then `GET /t` will just return the output
+
+
+    hello world
+
+
+That is, when the body filter sees a chunk containing the word "hello", then it will set the "eof" flag to true immediately, resulting in truncated but still valid responses.
+
+When the Lua code may change the length of the response body, then it is required to always clear out the `Content-Length` response header (if any) in a header filter to enforce streaming output, as in
+
+
+    location /foo {
+        # fastcgi_pass/proxy_pass/...
+
+        header_filter_by_lua 'ngx.header.content_length = nil';
+        body_filter_by_lua 'ngx.arg[1] = {string.len(arg[1]), "\n"}'
+    }
+
+
+Note that the following API functions are currently disabled within this context:
+
+* Output API functions (e.g., [ngx.say](http://wiki.nginx.org/HttpLuaModule#ngx.say) and [ngx.send_headers](http://wiki.nginx.org/HttpLuaModule#ngx.send_headers))
+* Control API functions (e.g., [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit) and [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec))

-Nginx API for Lua
-=================
-Introduction
-------------
-The various `*_by_lua` and `*_by_lua_file` configuration directives serve as gateways to the Lua API within the `nginx.conf` file. The Nginx Lua API described below can only be called within the user Lua code run in the context of these configuration directives.
-
-The API is exposed to Lua in the form of two standard packages `ngx` and `ndk`. These packages are in the default global scope within `ngx_lua` and are always available within `ngx_lua` directives.
+lua_socket_connect_timeout
+--------------------------
 
-The packages can be introduced into external Lua modules by using the [package.seeall](http://www.lua.org/manual/5.1/manual.html#pdf-package.seeall) option:
+**syntax:** *lua_socket_connect_timeout &lt;time&gt;*
 
+**default:** *lua_socket_connect_timeout 60s*
 
-    module("my_module", package.seeall)
+**context:** *http, server, location*
 
-    function say(a) ngx.say(a) end
+This directive controls the default timeout value used in TCP/unix-domain socket object's [connect](http://wiki.nginx.org/HttpLuaModule#tcpsock:connect) method and can be overridden by the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method.
 
+The `<time>` argument can be an integer, with an optional time unit, like `s` (second), `ms` (millisecond), `m` (minute). The default time unit is `s`, i.e., "second". The default setting is `60s`.
 
-Alternatively, they can be imported to external Lua modules by using file scoped local Lua variables:

+When the connection pool exceeds the available size limit, the least recently used (idle) connection already in the pool will be closed to make room for the current connection.
 
-Setting `ngx.var.Foo` to a `nil` value will unset the `$Foo` Nginx variable. 
+Note that the cosocket connection pool is per nginx worker process rather than per nginx server instance, so so size limit specified here also applies to every single nginx worker process.

+
+Enables or disables response caching for HTTP 1.0 (or older) requests. This buffering mechanism is mainly used for HTTP 1.0 keep-alive which replies on a proper `Content-Length` response header.
+
+If the Lua code explicitly sets a `Content-Length` response header before sending the headers (either explicitly via [ngx.send_headers](http://wiki.nginx.org/HttpLuaModule#ngx.send_headers) or implicitly via the first [ngx.say](http://wiki.nginx.org/HttpLuaModule#ngx.say) or [ngx.print](http://wiki.nginx.org/HttpLuaModule#ngx.print) call).
+
+To output very large response data in a streaming fashion (via the [ngx.flush](http://wiki.nginx.org/HttpLuaModule#ngx.flush) call, for example), this directive MUST be turned off to minimize memory usage.

+**context:** *http, server, location, location-if*
+
+Controls whether to transform underscores (`_`) in the response header names specified in the [ngx.header.HEADER](http://wiki.nginx.org/HttpLuaModule#ngx.header.HEADER) API to hypens (`-`).
+
+This directive was first introduced in the `v0.5.0rc32` release.
+
+lua_check_client_abort
+----------------------
+
+**syntax:** *lua_check_client_abort on|off*
+
+**default:** *lua_check_client_abort off*
+
+**context:** *http, server, location, location-if*
+
+This directive controls whether to check for premature client connection abortion.
+
+When this directive is turned on, the ngx_lua module will monitor the premature connection close event on the downstream connections. And when there is such an event, it will call the user Lua function callback (registered by [ngx.on_abort](http://wiki.nginx.org/HttpLuaModule#ngx.on_abort)) or just stop and clean up all the Lua "light threads" running in the current request's request handler when there is no user callback function registered.
+
+According to the current implementation, however, if the client closes the connection before the Lua code finishes reading the request body data via [ngx.req.socket](http://wiki.nginx.org/HttpLuaModule#ngx.req.socket), then ngx_lua will neither stop all the running "light threads" nor call the user callback (if [ngx.on_abort](http://wiki.nginx.org/HttpLuaModule#ngx.on_abort) has been called). Instead, the reading operation on [ngx.req.socket](http://wiki.nginx.org/HttpLuaModule#ngx.req.socket) will just return the error message "client aborted" as the second return value (the first return value is surely `nil`).
+
+When TCP keepalive is disabled, it is relying on the client side to close the socket gracefully (by sending a `FIN` packet or something like that). For (soft) real-time web applications, it is highly recommended to configure the [TCP keepalive](http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/overview.html) support in your system's TCP stack implementation in order to detect "half-open" TCP connections in time.
+
+For example, on Linux, you can configure the standard [listen](http://wiki.nginx.org/HttpCoreModule#listen) directive in your `nginx.conf` file like this:
+
+
+    listen 80 so_keepalive=2s:2s:8;
+
+
+On FreeBSD, you can only tune the system-wide configuration for TCP keepalive, for example:
+
+    # sysctl net.inet.tcp.keepintvl=2000
+    # sysctl net.inet.tcp.keepidle=2000
+
+This directive was first introduced in the `v0.7.4` release.
+
+See also [ngx.on_abort](http://wiki.nginx.org/HttpLuaModule#ngx.on_abort).
+
+Nginx API for Lua
+=================
+Introduction
+------------
+The various `*_by_lua` and `*_by_lua_file` configuration directives serve as gateways to the Lua API within the `nginx.conf` file. The Nginx Lua API described below can only be called within the user Lua code run in the context of these configuration directives.
+
+The API is exposed to Lua in the form of two standard packages `ngx` and `ndk`. These packages are in the default global scope within ngx_lua and are always available within ngx_lua directives.
+
+The packages can be introduced into external Lua modules like this:
+
+
+    local say = ngx.say
+
+    module(...)
+
+    function foo(a) 
+        say(a) 
+    end
+
+
+Use of the [package.seeall](http://www.lua.org/manual/5.1/manual.html#pdf-package.seeall) flag is strongly discouraged due to its various bad side-effects.
+
+It is also possible to directly require the packages in external Lua modules:
+
+
+    local ngx = require "ngx"
+    local ndk = require "ndk"
+
+
+The ability to require these packages was introduced in the `v0.2.1rc19` release.
+
+Network I/O operations in user code should only be done through the Nginx Lua API calls as the Nginx event loop may be blocked and performance drop off dramatically otherwise. Disk operations with relatively small amount of data can be done using the standard Lua `io` library but huge file reading and writing should be avoided wherever possible as they may block the Nginx process significantly. Delegating all network and disk I/O operations to Nginx's subrequests (via the [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) method and similar) is strongly recommended for maximum performance.
+
+ngx.arg
+-------
+**syntax:** *val = ngx.arg[index]*
+
+**context:** *set_by_lua*, body_filter_by_lua**
+
+When this is used in the context of the [set_by_lua](http://wiki.nginx.org/HttpLuaModule#set_by_lua) or [set_by_lua_file](http://wiki.nginx.org/HttpLuaModule#set_by_lua_file) directives, this table is read-only and holds the input arguments to the config directives:
+
+
+    value = ngx.arg[n]
+
+
+Here is an example
+
+
+    location /foo {
+        set $a 32;
+        set $b 56;
+ 
+        set_by_lua $res
+            'return tonumber(ngx.arg[1]) + tonumber(ngx.arg[2])'
+            $a $b;
+ 
+        echo $sum;
+    }
+
+
+that writes out `88`, the sum of `32` and `56`.
+
+When this table is used in the context of [body_filter_by_lua](http://wiki.nginx.org/HttpLuaModule#body_filter_by_lua) or [body_filter_by_lua_file](http://wiki.nginx.org/HttpLuaModule#body_filter_by_lua_file), the first element holds the input data chunk to the output filter code and the second element holds the boolean flag for the "eof" flag indicating the end of the whole output data stream.
+
+The data chunk and "eof" flag passed to the downstream Nginx output filters can also be overridden by assigning values directly to the corresponding table elements. When setting `nil` or an empty Lua string value to `ngx.arg[1]`, no data chunk will be passed to the downstream Nginx output filters at all.
+
+ngx.var.VARIABLE
+----------------
+**syntax:** *ngx.var.VAR_NAME*
+
+**context:** *set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua**
+
+Read and write Nginx variable values.
+
+
+    value = ngx.var.some_nginx_variable_name
+    ngx.var.some_nginx_variable_name = value
+
+
+Note that only already defined nginx variables can be written to.
+For example:
+
+
+    location /foo {
+        set $my_var ''; # this line is required to create $my_var at config time
+        content_by_lua '
+            ngx.var.my_var = 123;
+            ...
+        ';
+    }
+
+
+That is, nginx variables cannot be created on-the-fly.
+
+Some special nginx variables like `$args` and `$limit_rate` can be assigned a value,
+some are not, like `$arg_PARAMETER`.
+
+Nginx regex group capturing variables `$1`, `$2`, `$3`, and etc, can be read by this
+interface as well, by writing `ngx.var[1]`, `ngx.var[2]`, `ngx.var[3]`, and etc.
+
+Setting `ngx.var.Foo` to a `nil` value will unset the `$Foo` Nginx variable. 
+
+
+    ngx.var.args = nil
+
+
+**WARNING** When reading from an Nginx variable, Nginx will allocate memory in the per-request memory pool which is freed only at request termination. So when you need to read from an Nginx variable repeatedly in your Lua code, cache the Nginx variable value to your own Lua variable, for example,
+
+
+    local val = ngx.var.some_var
+    --- use the val repeatedly later
+
+
+to prevent (temporary) memory leaking within the current request's lifetime.

-For instance,
+ngx.shared.DICT.flush_expired
+-----------------------------
+**syntax:** *flushed = ngx.shared.DICT:flush_expired(max_count?)*
 
+**context:** *init_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua**
 
-    local res = ndk.set_var.set_escape_uri('a/b');
-    -- now res == 'a%2fb'
+Flushes out the expired items in the dictionary, up to the maximal number specified by the optional `max_count` argument. When the `max_count` argument is given `0` or not given at all, then it means unlimited. Returns the number of items that have actually been flushed.
 
+This feature was first introduced in the `v0.6.3` release.
 
-Similarly, the following directives provided by [HttpEncryptedSessionModule](http://wiki.nginx.org/HttpEncryptedSessionModule) can be invoked from within Lua too:
+See also [ngx.shared.DICT.flush_all](http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT.flush_all) and [ngx.shared.DICT](http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT).

-* [set_decrypt_session](http://wiki.nginx.org/HttpEncryptedSessionModule#set_decrypt_session)
+ngx.shared.DICT.get_keys
+------------------------
+**syntax:** *keys = ngx.shared.DICT:get_keys(max_count?)*
 
-This feature requires the [ngx_devel_kit](https://github.com/simpl/ngx_devel_kit) module.
+**context:** *init_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua**
 
-HTTP 1.0 support
-================
+Fetch a list of the keys from the dictionary, up to `<max_count>`.
 
-The HTTP 1.0 protocol does not support chunked outputs and always requires an
-explicit `Content-Length` header when the response body is non-empty. So when
-an HTTP 1.0 request is present, This module will automatically buffer all the
-outputs of user calls of [ngx.say](http://wiki.nginx.org/HttpLuaModule#ngx.say) and [ngx.print](http://wiki.nginx.org/HttpLuaModule#ngx.print) and
-postpone sending response headers until it sees all the outputs in the response
-body, and at that time ngx_lua can calculate the total length of the body and
-construct a proper `Content-Length` header for the HTTP 1.0 client.
+By default, only the first 1024 keys (if any) are returned. When the `<max_count>` argument is given the value `0`, then all the keys will be returned even there is more than 1024 keys in the dictionary.
 
-Note that, common HTTP benchmark tools like `ab` and `http_load` always issue
-HTTP 1.0 requests by default. To force `curl` to send HTTP 1.0 requests, use
-the `-0` option.
+**WARNING** Be careful when calling this method on dictionaries with a really huge number of keys. This method may lock the dictionary for quite a while and block all the nginx worker processes that are trying to access the dictionary.
 
-Data Sharing within an Nginx Worker
-===================================
+This feature was first introduced in the `v0.7.3` release.
 
-**NOTE: This mechanism behaves differently when code cache is turned off and should be considered a DIRTY TRICK. Note that backward compatibility is NOT guaranteed and that there may be other undesirable consequences. A new data sharing mechanism will be designed later.**
+ngx.socket.udp
+--------------
+**syntax:** *udpsock = ngx.socket.udp()*
 
-To globally share data among all the requests handled by the same nginx worker process, encapsulate the shared data into a Lua module, use the Lua `require` builtin to import the module, and then manipulate the shared data in Lua. This works because required Lua modules are loaded only once and all coroutines will share the same copy of the module. Note however that Lua global variables WILL NOT persist between requests because of the one-coroutine-per-request isolation design.
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
 
-Here is a complete small example:
+Creates and returns a UDP or datagram-oriented unix domain socket object (also known as one type of the "cosocket" objects). The following methods are supported on this object:
 
+* [setpeername](http://wiki.nginx.org/HttpLuaModule#udpsock:setpeername)
+* [send](http://wiki.nginx.org/HttpLuaModule#udpsock:send)
+* [receive](http://wiki.nginx.org/HttpLuaModule#udpsock:receive)
+* [close](http://wiki.nginx.org/HttpLuaModule#udpsock:close)
+* [settimeout](http://wiki.nginx.org/HttpLuaModule#udpsock:settimeout)
 
-    -- mydata.lua
-    module("mydata", package.seeall)
- 
-    local data = {
-        dog = 3,
-        cat = 4,
-        pig = 5,
-    }
- 
-    function get_age(name)
-        return data[name]
-    end
+It is intended to be compatible with the UDP API of the [LuaSocket](http://w3.impa.br/~diego/software/luasocket/udp.html) library but is 100% nonblocking out of the box.
 
+This feature was first introduced in the `v0.5.7` release.
 
-and then accessing it from `nginx.conf`:
+See also [ngx.socket.tcp](http://wiki.nginx.org/HttpLuaModule#ngx.socket.tcp).
 
+udpsock:setpeername
+-------------------
+**syntax:** *ok, err = udpsock:setpeername(host, port)*
 
-    location /lua {
-        content_lua_by_lua '
-            local mydata = require("mydata")
-            ngx.say(mydata.get_age("dog"))
-        ';
-    }
+**syntax:** *ok, err = udpsock:setpeername("unix:/path/to/unix-domain.socket")*
 
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
 
-The `mydata` module in this example will only be loaded and run on the first request to the location `/lua`,
-and all subsequent requests to the same nginx worker process will use the reloaded instance of the
-module as well as the same copy of the data in it, until a `HUP` signal is sent to the Nginx master process to force a reload.
-This data sharing technique is essential for high performance Lua applications based on this module.
+Attempts to connect a UDP socket object to a remote server or to a datagram unix domain socket file. Because the datagram protocol is actually connection-less, this method does not really establish a "connection", but only just set the name of the remote peer for subsequent read/write operations.
 
-Note that this data sharing is on a *per-worker* basis and not on a ''per-server' basis'. That is, when there are multiple nginx worker processes under an Nginx master, data sharing cannot cross the process boundary between these workers. 
+Both IP addresses and domain names can be specified as the `host` argument. In case of domain names, this method will use Nginx core's dynamic resolver to parse the domain name without blocking and it is required to configure the [resolver](http://wiki.nginx.org/HttpCoreModule#resolver) directive in the `nginx.conf` file like this:
 
-If server wide data sharing is required:
-1. Use the [ngx.shared.DICT](http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT) API provied by this module.
-1. Use only a single nginx worker and a single server. This is however not recommended when there is a multi core CPU or multiple CPUs in a single machine.
-1. Use data storage mechanisms such as `memcached`, `redis`, `MySQL` or `PostgreSQL`. [The ngx_openresty bundle](http://openresty.org) associated with this module comes with a set of companion Nginx modules that provide interfaces with these data storage mechanisms.  See the [HttpMemcModule](http://wiki.nginx.org/HttpMemcModule), [HttpRedis2Module](http://wiki.nginx.org/HttpRedis2Module), [HttpDrizzleModule](http://wiki.nginx.org/HttpDrizzleModule) and [HttpPostgresModule](http://github.com/FRiCKLE/ngx_postgres/) modules for details
 
-Known Issues
-============
+    resolver 8.8.8.8;  # use Google's public DNS nameserver
 
-Lua Coroutine Yielding/Resuming
--------------------------------
-* As the module's predefined Nginx I/O API uses the coroutine yielding/resuming mechanism, user code should not call any Lua modules that use the Lua coroutine mechanism in order to prevent conflicts with the module's predefined Nginx API methods such as [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) (Actually, coroutine modules have been masked off in [content_by_lua](http://wiki.nginx.org/HttpLuaModule#content_by_lua) directives and others). This limitation is significant and work is ongoing on an alternative coroutine implementation that can fit into the Nginx event model to address this. When this is done, it will be possible to use the Lua coroutine mechanism freely as it is in standard Lua implementations.
-* Lua's `dofile` builtin is implemented as a C function in both Lua 5.1 and LuaJIT 2.0 and when [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) is called, [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit) or [ngx.req.read_body](http://wiki.nginx.org/HttpLuaModule#ngx.req.read_body) or similar in the file to be loaded by `dofile`, a coroutine yield across the C function boundary will be initiated. This however is not allowed within ngx_lua and will usually result in error messages like `lua handler aborted: runtime error: attempt to yield across C-call boundary`. To avoid this, define a real Lua module and use the Lua `require` builtin instead.
-* Because the standard Lua 5.1 interpreter's VM is not fully resumable, the methods [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture), [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi), [ngx.redirect](http://wiki.nginx.org/HttpLuaModule#ngx.redirect), [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), and [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit) cannot be used within the context of a Lua [pcall()](http://www.lua.org/manual/5.1/manual.html#pdf-pcall) or [xpcall()](http://www.lua.org/manual/5.1/manual.html#pdf-xpcall) when the standard Lua 5.1 interpreter is used and the `attempt to yield across metamethod/C-call boundary` error will be produced. Please use LuaJIT 2.0, which supports a fully resumable VM, to avoid this.
 
-Lua Variable Scope
-------------------
-Care should be taken when importing modules and this form should be used:
+If the nameserver returns multiple IP addresses for the host name, this method will pick up one randomly.
 
+In case of error, the method returns `nil` followed by a string describing the error. In case of success, the method returns `1`.
 
-        local xxx = require('xxx')
+Here is an example for connecting to a UDP (memcached) server:
 
 
-	instead of the old deprecated form:
+    location /test {
+        resolver 8.8.8.8;
 
+        content_by_lua '
+            local sock = ngx.socket.udp()
+            local ok, err = sock:setpeername("my.memcached.server.domain", 11211)
+            if not ok then
+                ngx.say("failed to connect to memcached: ", err)
+                return
+            end
+            ngx.say("successfully connected to memcached!")
+            sock:close()
+        ';
+    }
 
-        require('xxx')
 
+Connecting to a datagram unix domain socket file is also possible:
 
-	If the old form is required, force reload the module for every request by using the `package.loaded.<module>` command:
 
+    local sock = ngx.socket.udp()
+    local ok, err = sock:setpeername("unix:/tmp/some-datagram-service.sock")
+    if not ok then
+        ngx.say("failed to connect to the datagram unix domain socket: ", err)
+        return
+    end
 
-        package.loaded.xxx = nil
-        require('xxx')
 
+assuming the datagram service is listening on the unix domain socket file `/tmp/some-datagram-service.sock`.
 
-It is recommended to always place the following piece of code at the end of Lua modules that use the [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) or [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi) directives to prevent casual use of module-level global variables that are shared among *all* requests:
+Calling this method on an already connected socket object will cause the original connection to be closed first.
 
+This method was first introduced in the `v0.5.7` release.
 
-    getmetatable(foo.bar).__newindex = function (table, key, val)
-        error('Attempt to write to undeclared variable "' .. key .. '": '
-                .. debug.traceback())
-    end
+udpsock:send
+------------
+**syntax:** *ok, err = udpsock:send(data)*
 
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
 
-Assuming the current Lua module is named `foo.bar`, this will guarantee that local variables in module `foo.bar` functions have been declared as "local". It prevents undesirable race conditions while accessing such variables. See [Data Sharing within an Nginx Worker](http://wiki.nginx.org/HttpLuaModule#Data_Sharing_within_an_Nginx_Worker) for the reasons behind this.
+Sends data on the current UDP or datagram unix domain socket object.
 
-Locations With [HttpEchoModule](http://wiki.nginx.org/HttpEchoModule) Directives
---------------------------------------------
-The [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) and [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi) directives cannot capture locations that include the [echo_location](http://wiki.nginx.org/HttpEchoModule#echo_location), [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async), [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest), or [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) directives.
+In case of success, it returns `1`. Otherwise, it returns `nil` and a string describing the error.
 
+The input argument `data` can either be a Lua string or a (nested) Lua table holding string fragments. In case of table arguments, this method will copy all the string elements piece by piece to the underlying Nginx socket send buffers, which is usually optimal than doing string concatenation operations on the Lua land.
 
-    location /foo {
-        content_by_lua '
-            res = ngx.location.capature("/bar")
-        ';
-    }
-    location /bar {
-        echo_location /blah;
-    }
-    location /blah {
-        echo "Success!";
-    }
+This feature was first introduced in the `v0.5.7` release.
 
+udpsock:receive
+---------------
+**syntax:** *data, err = udpsock:receive(size?)*
 
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
 
-    $ curl -i http://example.com/foo
+Receives data from the UDP or datagram unix domain socket object with an optional receive buffer size argument, `size`.
 
+This method is a synchronous operation and is 100% nonblocking.
 
-will not work as expected.
+In case of success, it returns the data received; in case of error, it returns `nil` with a string describing the error.
 
-Special PCRE Sequences
-----------------------
-PCRE sequences such as `\d`, `\s`, or `\w`, require special attention because in string literals, the backslash character, `\`, is stripped out by both the Lua language parser and by the Nginx config file parser before processing. So the following snippet will not work as expected:
+If the `size` argument is specified, then this method will use this size as the receive buffer size. But when this size is greater than `8192`, then `8192` will be used instead.
 
+If no argument is specified, then the maximal buffer size, `8192` is assumed.
 
-    # nginx.conf
-    ? location /test {
-    ?     content_by_lua '
-    ?         local regex = "\d+"  -- THIS IS WRONG!!
-    ?         local m = ngx.re.match("hello, 1234", regex)
-    ?         if m then ngx.say(m[0]) else ngx.say("not matched!") end
-    ?     ';
-    ? }
-    # evaluates to "not matched!"
+Timeout for the reading operation is controlled by the [lua_socket_read_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_read_timeout) config directive and the [settimeout](http://wiki.nginx.org/HttpLuaModule#udpsock:settimeout) method. And the latter takes priority. For example:
 
 
-To avoid this, *double* escape the backslash:
+    sock:settimeout(1000)  -- one second timeout
+    local data, err = sock:receive()
+    if not data then
+        ngx.say("failed to read a packet: ", data)
+        return
+    end
+    ngx.say("successfully read a packet: ", data)
 
 
-    # nginx.conf
-    location /test {
-        content_by_lua '
-            local regex = "\\\\d+"
-            local m = ngx.re.match("hello, 1234", regex)
-            if m then ngx.say(m[0]) else ngx.say("not matched!") end
-        ';
-    }
-    # evaluates to "1234"
+It is important here to call the [settimeout](http://wiki.nginx.org/HttpLuaModule#udpsock:settimeout) method *before* calling this method.
 
+This feature was first introduced in the `v0.5.7` release.
 
-Here, `\\\\d+` is stripped down to `\\d+` by the Nginx config file parser and this is further stripped down to `\d+` by the Lua language parser before running.
+udpsock:close
+-------------
+**syntax:** *ok, err = udpsock:close()*
 
-Alternatively, the regex pattern can be presented as a long-bracketed lua string literal by encasing it in "long brackets", `[[...]]`, in which case backslashes have to only be escaped once for the Nginx config file parser. 
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
 
+Closes the current UDP or datagram unix domain socket. It returns the `1` in case of success and returns `nil` with a string describing the error otherwise.
 
-    # nginx.conf
-    location /test {
-        content_by_lua '
-            local regex = [[\\d+]]
-            local m = ngx.re.match("hello, 1234", regex)
-            if m then ngx.say(m[0]) else ngx.say("not matched!") end
-        ';
-    }
-    # evaluates to "1234"
+Socket objects that have not invoked this method (and associated connections) will be closed when the socket object is released by the Lua GC (Garbage Collector) or the current client HTTP request finishes processing.
 
+This feature was first introduced in the `v0.5.7` release.
 
-Here, `[[\\d+]]` is stripped down to `[[\d+]]` by the Nginx config file parser and this is processed correctly.
+udpsock:settimeout
+------------------
+**syntax:** *udpsock:settimeout(time)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Set the timeout value in milliseconds for subsequent socket operations (like [receive](http://wiki.nginx.org/HttpLuaModule#udpsock:receive)).
+
+Settings done by this method takes priority over those config directives, like [lua_socket_read_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_read_timeout).
+
+This feature was first introduced in the `v0.5.7` release.
+
+ngx.socket.tcp
+--------------
+**syntax:** *tcpsock = ngx.socket.tcp()*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Creates and returns a TCP or stream-oriented unix domain socket object (also known as one type of the "cosocket" objects). The following methods are supported on this object:
+
+* [connect](http://wiki.nginx.org/HttpLuaModule#tcpsock:connect)
+* [send](http://wiki.nginx.org/HttpLuaModule#tcpsock:send)
+* [receive](http://wiki.nginx.org/HttpLuaModule#tcpsock:receive)
+* [close](http://wiki.nginx.org/HttpLuaModule#tcpsock:close)
+* [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout)
+* [setoption](http://wiki.nginx.org/HttpLuaModule#tcpsock:setoption)
+* [receiveuntil](http://wiki.nginx.org/HttpLuaModule#tcpsock:receiveuntil)
+* [setkeepalive](http://wiki.nginx.org/HttpLuaModule#tcpsock:setkeepalive)
+* [getreusedtimes](http://wiki.nginx.org/HttpLuaModule#tcpsock:getreusedtimes)
+
+It is intended to be compatible with the TCP API of the [LuaSocket](http://w3.impa.br/~diego/software/luasocket/tcp.html) library but is 100% nonblocking out of the box. Also, we introduce some new APIs to provide more functionalities.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+See also [ngx.socket.udp](http://wiki.nginx.org/HttpLuaModule#ngx.socket.udp).
+
+tcpsock:connect
+---------------
+**syntax:** *ok, err = tcpsock:connect(host, port, options_table?)*
+
+**syntax:** *ok, err = tcpsock:connect("unix:/path/to/unix-domain.socket", options_table?)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Attempts to connect a TCP socket object to a remote server or to a stream unix domain socket file without blocking.
+
+Before actually resolving the host name and connecting to the remote backend, this method will always look up the connection pool for matched idle connections created by previous calls of this method (or the [ngx.socket.connect](http://wiki.nginx.org/HttpLuaModule#ngx.socket.connect) function).
+
+Both IP addresses and domain names can be specified as the `host` argument. In case of domain names, this method will use Nginx core's dynamic resolver to parse the domain name without blocking and it is required to configure the [resolver](http://wiki.nginx.org/HttpCoreModule#resolver) directive in the `nginx.conf` file like this:
+
+
+    resolver 8.8.8.8;  # use Google's public DNS nameserver
+
+
+If the nameserver returns multiple IP addresses for the host name, this method will pick up one randomly.
+
+In case of error, the method returns `nil` followed by a string describing the error. In case of success, the method returns `1`.
+
+Here is an example for connecting to a TCP server:
+
+
+    location /test {
+        resolver 8.8.8.8;
+
+        content_by_lua '
+            local sock = ngx.socket.tcp()
+            local ok, err = sock:connect("www.google.com", 80)
+            if not ok then
+                ngx.say("failed to connect to google: ", err)
+                return
+            end
+            ngx.say("successfully connected to google!")
+            sock:close()
+        ';
+    }
+
+
+Connecting to a Unix Domain Socket file is also possible:
+
+
+    local sock = ngx.socket.tcp()
+    local ok, err = sock:connect("unix:/tmp/memcached.sock")
+    if not ok then
+        ngx.say("failed to connect to the memcached unix domain socket: ", err)
+        return
+    end
+
+
+assuming memcached (or something else) is listening on the unix domain socket file `/tmp/memcached.sock`.
+
+Timeout for the connecting operation is controlled by the [lua_socket_connect_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_connect_timeout) config directive and the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method. And the latter takes priority. For example:
+
+
+    local sock = ngx.socket.tcp()
+    sock:settimeout(1000)  -- one second timeout
+    local ok, err = sock:connect(host, port)
+
+
+It is important here to call the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method *before* calling this method.
+
+Calling this method on an already connected socket object will cause the original connection to be closed first.
+
+An optional Lua table can be specified as the last argument to this method to specify various connect options:
+
+* `pool`
+	specify a custom name for the connection pool being used. If omitted, then the connection pool name will be generated from the string template `"<host>:<port>"` or `"<unix-socket-path>"`.
+
+The support for the options table argument was first introduced in the `v0.5.7` release.
+
+This method was first introduced in the `v0.5.0rc1` release.

+Sends data without blocking on the current TCP or Unix Domain Socket connection.
+
+This method is a synchronous operation that will not return until *all* the data has been flushed into the system socket send buffer or an error occurs.
+
+In case of success, it returns the total number of bytes that have been sent. Otherwise, it returns `nil` and a string describing the error.
+
+The input argument `data` can either be a Lua string or a (nested) Lua table holding string fragments. In case of table arguments, this method will copy all the string elements piece by piece to the underlying Nginx socket send buffers, which is usually optimal than doing string concatenation operations on the Lua land.
+
+Timeout for the sending operation is controlled by the [lua_socket_send_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_send_timeout) config directive and the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method. And the latter takes priority. For example:
+
+
+    sock:settimeout(1000)  -- one second timeout
+    local bytes, err = sock:send(request)
+
+
+It is important here to call the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method *before* calling this method.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:receive
+---------------
+**syntax:** *data, err, partial = tcpsock:receive(size)*
+
+**syntax:** *data, err, partial = tcpsock:receive(pattern?)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Receives data from the connected socket according to the reading pattern or size.
+
+This method is a synchronous operation just like the [send](http://wiki.nginx.org/HttpLuaModule#tcpsock:send) method and is 100% nonblocking.
+
+In case of success, it returns the data received; in case of error, it returns `nil` with a string describing the error and the partial data received so far.
+
+If a number-like argument is specified (including strings that look like numbers), then it is interpreted as a size. This method will not return until it reads exactly this size of data or an error occurs.
+
+If a non-number-like string argument is specified, then it is interpreted as a "pattern". The following patterns are supported:
+
+* `'*a'`: reads from the socket until the connection is closed. No end-of-line translation is performed;
+* `'*l'`: reads a line of text from the socket. The line is terminated by a `Line Feed` (LF) character (ASCII 10), optionally preceded by a `Carriage Return` (CR) character (ASCII 13). The CR and LF characters are not included in the returned line. In fact, all CR characters are ignored by the pattern.
+
+If no argument is specified, then it is assumed to be the pattern `'*l'`, that is, the line reading pattern.
+
+Timeout for the reading operation is controlled by the [lua_socket_read_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_read_timeout) config directive and the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method. And the latter takes priority. For example:
+
+
+    sock:settimeout(1000)  -- one second timeout
+    local line, err, partial = sock:receive()
+    if not line then
+        ngx.say("failed to read a line: ", err)
+        return
+    end
+    ngx.say("successfully read a line: ", line)
+
+
+It is important here to call the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method *before* calling this method.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:receiveuntil
+--------------------
+**syntax:** *iterator = tcpsock:receiveuntil(pattern, options?)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+This method returns an iterator Lua function that can be called to read the data stream until it sees the specified pattern or an error occurs.
+
+Here is an example for using this method to read a data stream with the boundary sequence `--abcedhb`:
+
+
+    local reader = sock:receiveuntil("\r\n--abcedhb")
+    local data, err, partial = reader()
+    if not data then
+        ngx.say("failed to read the data stream: ", err)
+    end
+    ngx.say("read the data stream: ", data)
+
+
+When called without any argument, the iterator function returns the received data right *before* the specified pattern string in the incoming data stream. So for the example above, if the incoming data stream is `'hello, world! -agentzh\r\n--abcedhb blah blah'`, then the string `'hello, world! -agentzh'` will be returned.
+
+In case of error, the iterator function will return `nil` along with a string describing the error and the partial data bytes that have been read so far.
+
+The iterator function can be called multiple times and can be mixed safely with other cosocket method calls or other iterator function calls.
+
+The iterator function behaves differently (i.e., like a real iterator) when it is called with a `size` argument. That is, it will read that `size` of data on each invocation and will return `nil` at the last invocation (either sees the boundary pattern or meets an error). For the last successful invocation of the iterator function, the `err` return value will be `nil` too. The iterator function will be reset after the last successful invocation that returns `nil` data and `nil` error. Consider the following example:
+
+
+    local reader = sock:receiveuntil("\r\n--abcedhb")
+
+    while true then
+        local data, err, partial = reader(4)
+        if not data then
+            if err then
+                ngx.say("failed to read the data stream: ", err)
+                break
+            end
+
+            ngx.say("read done")
+            break
+        end
+        ngx.say("read chunk: [", data, "]")
+    end
+
+
+Then for the incoming data stream `'hello, world! -agentzh\r\n--abcedhb blah blah'`, we shall get the following output from the sample code above:
+
+
+    read chunk: [hell]
+    read chunk: [o, w]
+    read chunk: [orld]
+    read chunk: [! -a]
+    read chunk: [gent]
+    read chunk: [zh]
+    read done
+
+
+Note that, the actual data returned *might* be a little longer than the size limit specified by the `size` argument when the boundary pattern has ambiguity for streaming parsing. Near the boundary of the data stream, the data string actually returned could also be shorter than the size limit.
+
+Timeout for the iterator function's reading operation is controlled by the [lua_socket_read_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_read_timeout) config directive and the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method. And the latter takes priority. For example:
+
+
+    local readline = sock:receiveuntil("\r\n")
+
+    sock:settimeout(1000)  -- one second timeout
+    line, err, partial = readline()
+    if not line then
+        ngx.say("failed to read a line: ", err)
+        return
+    end
+    ngx.say("successfully read a line: ", line)
+
+
+It is important here to call the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method *before* calling the iterator function (note that the `receiveuntil` call is irrelevant here).
+
+As from the `v0.5.1` release, this method also takes an optional `options` table argument to control the behavior. The following options are supported:
+
+* `inclusive`
+
+The `inclusive` takes a boolean value to control whether to include the pattern string in the returned data string. Default to `false`. For example,
+
+
+    local reader = tcpsock:receiveuntil("_END_", { inclusive = true })
+    local data = reader()
+    ngx.say(data)
+
+
+Then for the input data stream `"hello world _END_ blah blah blah"`, then the example above will output `hello world _END_`, including the pattern string `_END_` itself.
+
+This method was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:close
+-------------
+**syntax:** *ok, err = tcpsock:close()*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Closes the current TCP or stream unix domain socket. It returns the `1` in case of success and returns `nil` with a string describing the error otherwise.
+
+Note that there is no need to call this method on socket objects that have invoked the [setkeepalive](http://wiki.nginx.org/HttpLuaModule#tcpsock:setkeepalive) method because the socket object is already closed (and the current connection is saved into the built-in connection pool).
+
+Socket objects that have not invoked this method (and associated connections) will be closed when the socket object is released by the Lua GC (Garbage Collector) or the current client HTTP request finishes processing.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:settimeout
+------------------
+**syntax:** *tcpsock:settimeout(time)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Set the timeout value in milliseconds for subsequent socket operations ([connect](http://wiki.nginx.org/HttpLuaModule#tcpsock:connect), [receive](http://wiki.nginx.org/HttpLuaModule#tcpsock:receive), and iterators returned from [receiveuntil](http://wiki.nginx.org/HttpLuaModule#tcpsock:receiveuntil)).
+
+Settings done by this method takes priority over those config directives, i.e., [lua_socket_connect_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_connect_timeout), [lua_socket_send_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_send_timeout), and [lua_socket_read_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_read_timeout).
+
+Note that this method does *not* affect the [lua_socket_keepalive_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_keepalive_timeout) setting; the `timeout` argument to the [setkeepalive](http://wiki.nginx.org/HttpLuaModule#tcpsock:setkeepalive) method should be used for this purpose instead.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:setoption
+-----------------
+**syntax:** *tcpsock:setoption(option, value?)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+This function is added for [LuaSocket](http://w3.impa.br/~diego/software/luasocket/tcp.html) API compatibility and does nothing for now. Its functionality will be implemented in future.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:setkeepalive
+--------------------
+**syntax:** *ok, err = tcpsock:setkeepalive(timeout?, size?)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Puts the current socket's connection immediately into the cosocket built-in connection pool and keep it alive until other [connect](http://wiki.nginx.org/HttpLuaModule#tcpsock:connect) method calls request it or the associated maximal idle timeout is expired.
+
+The first optional argument, `timeout`, can be used to specify the maximal idle timeout (in milliseconds) for the current connection. If omitted, the default setting in the [lua_socket_keepalive_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_keepalive_timeout) config directive will be used. If the `0` value is given, then the timeout interval is unlimited.
+
+The second optional argument, `size`, can be used to specify the maximal number of connections allowed in the connection pool for the current server (i.e., the current host-port pair or the unix domain socket file path). Note that the size of the connection pool cannot be changed once the pool is created. When this argument is omitted, the default setting in the [lua_socket_pool_size](http://wiki.nginx.org/HttpLuaModule#lua_socket_pool_size) config directive will be used.
+
+When the connection pool exceeds the available size limit, the least recently used (idle) connection already in the pool will be closed to make room for the current connection.
+
+Note that the cosocket connection pool is per Nginx worker process rather than per Nginx server instance, so the size limit specified here also applies to every single Nginx worker process.
+
+Idle connections in the pool will be monitored for any exceptional events like connection abortion or unexpected incoming data on the line, in which cases the connection in question will be closed and removed from the pool.
+
+In case of success, this method returns `1`; otherwise, it returns `nil` and a string describing the error.
+
+This method also makes the current cosocket object enter the "closed" state, so there is no need to manually call the [close](http://wiki.nginx.org/HttpLuaModule#tcpsock:close) method on it afterwards.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+tcpsock:getreusedtimes
+----------------------
+**syntax:** *count, err = tcpsock:getreusedtimes()*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+This method returns the (successfully) reused times for the current connection. In case of error, it returns `nil` and a string describing the error.
+
+If the current connection does not come from the built-in connection pool, then this method always returns `0`, that is, the connection has never been reused (yet). If the connection comes from the connection pool, then the return value is always non-zero. So this method can also be used to determine if the current connection comes from the pool.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+ngx.socket.connect
+------------------
+**syntax:** *tcpsock, err = ngx.socket.connect(host, port)*
+
+**syntax:** *tcpsock, err = ngx.socket.connect("unix:/path/to/unix-domain.socket")*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+This function is a shortcut for combining [ngx.socket.tcp()](http://wiki.nginx.org/HttpLuaModule#ngx.socket.tcp) and the [connect()](http://wiki.nginx.org/HttpLuaModule#tcpsock:connect) method call in a single operation. It is actually implemented like this:
+
+
+    local sock = ngx.socket.tcp()
+    local ok, err = sock:connect(...)
+    if not ok then
+        return nil, err
+    end
+    return sock
+
+
+There is no way to use the [settimeout](http://wiki.nginx.org/HttpLuaModule#tcpsock:settimeout) method to specify connecting timeout for this method and the [lua_socket_connect_timeout](http://wiki.nginx.org/HttpLuaModule#lua_socket_connect_timeout) directive must be set at configure time instead.
+
+This feature was first introduced in the `v0.5.0rc1` release.
+
+ngx.get_phase
+-------------
+**syntax:** *str = ngx.get_phase()*
+
+**context:** *init_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua**
+
+Retrieves the current running phase name. Possible return values are
+
+* `init`

+
+coroutine.create
+----------------
+**syntax:** *co = coroutine.create(f)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Creates a user Lua coroutines with a Lua function, and returns a coroutine object.
+
+Similar to the standard Lua [coroutine.create](http://www.lua.org/manual/5.1/manual.html#pdf-coroutine.create) API, but works in the context of the Lua coroutines created by ngx_lua.

+
+coroutine.resume
+----------------
+**syntax:** *ok, ... = coroutine.resume(co, ...)*

+Resumes the executation of a user Lua coroutine object previously yielded or just created.
+
+Similar to the standard Lua [coroutine.resume](http://www.lua.org/manual/5.1/manual.html#pdf-coroutine.resume) API, but works in the context of the Lua coroutines created by ngx_lua.

+
+coroutine.yield
+---------------
+**syntax:** *... = coroutine.yield(co, ...)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Yields the executation of the current user Lua coroutine.
+
+Similar to the standard Lua [coroutine.yield](http://www.lua.org/manual/5.1/manual.html#pdf-coroutine.yield) API, but works in the context of the Lua coroutines created by ngx_lua.
+
+This API was first introduced in the `v0.6.0` release.
+
+coroutine.wrap
+--------------
+**syntax:** *co = coroutine.wrap(f)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Similar to the standard Lua [coroutine.wrap](http://www.lua.org/manual/5.1/manual.html#pdf-coroutine.wrap) API, but works in the context of the Lua coroutines created by ngx_lua.
+
+This API was first introduced in the `v0.6.0` release.
+
+coroutine.running
+-----------------
+**syntax:** *co = coroutine.running()*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Identical to the standard Lua [coroutine.running](http://www.lua.org/manual/5.1/manual.html#pdf-coroutine.running) API.
+
+This API was first enabled in the `v0.6.0` release.
+

+
+This API was first enabled in the `v0.6.0` release.
+
+ngx.thread.spawn
+----------------
+**syntax:** *co = ngx.thread.spawn(func, arg1, arg2, ...)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Spawns a new user "light thread" with the Lua function `func` as well as those optional arguments `arg1`, `arg2`, and etc. Returns a Lua thread (or Lua coroutine) object represents this "light thread".
+
+"Light threads" are just a special kind of Lua coroutines that are scheduled by the ngx_lua module.
+
+Before `ngx.thread.spawn` returns, the `func` will be called with those optional arguments until it returns, aborts with an error, or gets yielded due to I/O operations via the [Nginx API for Lua](http://wiki.nginx.org/HttpLuaModule#Nginx_API_for_Lua) (like [tcpsock:receive](http://wiki.nginx.org/HttpLuaModule#tcpsock:receive)).
+
+After `ngx.thread.spawn` returns, the newly-created "light thread" will keep running asynchronously usually at various I/O events.
+
+All the Lua code chunks running by [rewrite_by_lua](http://wiki.nginx.org/HttpLuaModule#rewrite_by_lua), [access_by_lua](http://wiki.nginx.org/HttpLuaModule#access_by_lua), and [content_by_lua](http://wiki.nginx.org/HttpLuaModule#content_by_lua) are in a boilerplate "light thread" created automatically by ngx_lua. Such boilerplate "light thread" are also called "entry threads".
+
+By default, the corresponding Nginx handler (e.g., [rewrite_by_lua](http://wiki.nginx.org/HttpLuaModule#rewrite_by_lua) handler) will not terminate until
+1. both the "entry thread" and all the user "light threads" terminates,
+1. a "light thread" (either the "entry thread" or a user "light thread" aborts by calling [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit), [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), [ngx.redirect](http://wiki.nginx.org/HttpLuaModule#ngx.redirect), or [ngx.req.set_uri(uri, true)](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_uri), or
+1. the "entry thread" terminates with a Lua error.
+
+When the user "light thread" terminates with a Lua error, however, it will not abort other running "light threads" like the "entry thread" does.
+
+Due to the limitation in the Nginx subrequest model, it is not allowed to abort a running Nginx subrequest in general. So it is also prohibited to abort a running "light thread" that is pending on one ore more Nginx subrequests. You must call [ngx.thread.wait](http://wiki.nginx.org/HttpLuaModule#ngx.thread.wait) to wait for those "light thread" to terminate before quitting the "world". A notable exception here is that you can abort pending subrequests by calling [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit) with and only with the status code `ngx.ERROR` (-1), `408`, `444`, or `499`.
+
+The "light threads" are not scheduled in a pre-emptive way. In other words, no time-slicing is performed automatically. A "light thread" will keep running exclusively on the CPU until
+1. a (nonblocking) I/O operation cannot be completed in a single run,
+1. it calls [coroutine.yield](http://wiki.nginx.org/HttpLuaModule#coroutine.yield) to actively give up execution, or
+1. it is aborted by a Lua error or an invocation of [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit), [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), [ngx.redirect](http://wiki.nginx.org/HttpLuaModule#ngx.redirect), or [ngx.req.set_uri(uri, true)](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_uri).
+
+For the first two cases, the "light thread" will usually be resumed later by the ngx_lua scheduler unless a "stop-the-world" event happens.
+
+User "light threads" can create "light threads" themselves and normal user coroutiens created by [coroutine.create](http://wiki.nginx.org/HttpLuaModule#coroutine.create) can also create "light threads". The coroutine (be it a normal Lua coroutine or a "light thread") that directly spawns the "light thread" is called the "parent coroutine" for the "light thread" newly spawned.
+
+The "parent coroutine" can call [ngx.thread.wait](http://wiki.nginx.org/HttpLuaModule#ngx.thread.wait) to wait on the termination of its child "light thread".
+
+You can call coroutine.status() and coroutine.yield() on the "light thread" coroutines.
+
+The status of the "light thread" coroutine can be "zombie" if
+1. the current "light thread" already terminates (either successfully or with an error),
+1. its parent coroutine is still alive, and
+1. its parent coroutine is not waiting on it with [ngx.thread.wait](http://wiki.nginx.org/HttpLuaModule#ngx.thread.wait).
+
+The following example demonstrates the use of coroutine.yield() in the "light thread" coroutines
+to do manual time-slicing:
+
+
+    local yield = coroutine.yield
+
+    function f()
+        local self = coroutine.running()
+        ngx.say("f 1")
+        yield(self)
+        ngx.say("f 2")
+        yield(self)
+        ngx.say("f 3")
+    end
+
+    local self = coroutine.running()
+    ngx.say("0")
+    yield(self)
+
+    ngx.say("1")
+    ngx.thread.spawn(f)
+
+    ngx.say("2")
+    yield(self)
+
+    ngx.say("3")
+    yield(self)
+
+    ngx.say("4")
+
+
+Then it will generate the output
+
+
+    0
+    1
+    f 1
+    2
+    f 2
+    3
+    f 3
+    4
+
+
+"Light threads" are mostly useful for doing concurrent upstream requests in a single Nginx request handler, kinda like a generalized version of [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi) that can work with all the [Nginx API for Lua](http://wiki.nginx.org/HttpLuaModule#Nginx_API_for_Lua). The following example demonstrates parallel requests to MySQL, Memcached, and upstream HTTP services in a single Lua handler, and outputting the results in the order that they actually return (very much like the Facebook BigPipe model):
+
+
+    -- query mysql, memcached, and a remote http service at the same time,
+    -- output the results in the order that they
+    -- actually return the results.
+
+    local mysql = require "resty.mysql"
+    local memcached = require "resty.memcached"
+
+    local function query_mysql()
+        local db = mysql:new()
+        db:connect{

+
+    local function query_http()
+        local res = ngx.location.capture("/my-http-proxy")

+    end
+
+    ngx.thread.spawn(query_mysql)      -- create thread 1
+    ngx.thread.spawn(query_memcached)  -- create thread 2
+    ngx.thread.spawn(query_http)       -- create thread 3 
+
+
+This API was first enabled in the `v0.7.0` release.
+
+ngx.thread.wait
+---------------
+**syntax:** *ok, res1, res2, ... = ngx.thread.wait(thread1, thread2, ...)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Waits on one or more child "light threads" and returns the results of the first "light thread" that terminates (either successfully or with an error).
+
+The arguments `thread1`, `thread2`, and etc are the Lua thread objects returned by earlier calls of [ngx.thread.spawn](http://wiki.nginx.org/HttpLuaModule#ngx.thread.spawn).
+
+The return values have exactly the same meaning as [coroutine.resume](http://wiki.nginx.org/HttpLuaModule#coroutine.resume), that is, the first value returned is a boolean value indicating whether the "light thread" terminates successfully or not, and subsequent values returned are the return values of the user Lua function that was used to spawn the "light thread" (in case of success) or the error object (in case of failure).
+
+Only the direct "parent coroutine" can wait on its child "light thread", otherwise a Lua exception will be raised.
+
+The following example demonstrates the use of `ngx.thread.wait` and [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) to emulate [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi):
+
+
+    local capture = ngx.location.capture
+    local spawn = ngx.thread.spawn
+    local wait = ngx.thread.wait
+    local say = ngx.say
+
+    local function fetch(uri)
+        return capture(uri)
+    end
+
+    local threads = {
+        spawn(fetch, "/foo"),
+        spawn(fetch, "/bar"),
+        spawn(fetch, "/baz")
+    }
+
+    for i = 1, #threads do
+        local ok, res = wait(threads[i])
+        if not ok then
+            say(i, ": failed to run: ", res)
+        else
+            say(i, ": status: ", res.status)
+            say(i, ": body: ", res.body)
+        end
+    end
+
+
+Here it essentially implements the "wait all" model.
+
+And below is an example demonstrating the "wait any" model:
+
+
+    function f()
+        ngx.sleep(0.2)
+        ngx.say("f: hello")
+        return "f done"
+    end
+
+    function g()
+        ngx.sleep(0.1)
+        ngx.say("g: hello")
+        return "g done"
+    end
+
+    local tf, err = ngx.thread.spawn(f)
+    if not tf then
+        ngx.say("failed to spawn thread f: ", err)
+        return
+    end
+
+    ngx.say("f thread created: ", coroutine.status(tf))
+
+    local tg, err = ngx.thread.spawn(g)
+    if not tg then
+        ngx.say("failed to spawn thread g: ", err)
+        return
+    end
+
+    ngx.say("g thread created: ", coroutine.status(tg))
+
+    ok, res = ngx.thread.wait(tf, tg)
+    if not ok then
+        ngx.say("failed to wait: ", res)
+        return
+    end
+
+    ngx.say("res: ", res)
+
+    -- stop the "world", aborting other running threads
+    ngx.exit(ngx.OK)
+
+
+And it will generate the following output:
+
+
+    f thread created: running
+    g thread created: running
+    g: hello
+    res: g done
+
+
+This API was first enabled in the `v0.7.0` release.
+
+ngx.on_abort
+------------
+**syntax:** *ok, err = ngx.on_abort(callback)*
+
+**context:** *rewrite_by_lua*, access_by_lua*, content_by_lua**
+
+Registers a user Lua function as the callback which gets called automatically when the client closes the (downstream) connection prematurely.
+
+Returns `1` if the callback is registered successfully or returns `nil` and a string describing the error otherwise.
+
+All the [Nginx API for Lua](http://wiki.nginx.org/HttpLuaModule#Nginx_API_for_Lua) can be used in the callback function because the function is run in a special "light thread", just as those "light threads" created by [ngx.thread.spawn](http://wiki.nginx.org/HttpLuaModule#ngx.thread.spawn).
+
+The callback function can decide what to do with the client abortion event all by itself. For example, it can simply ignore the event by doing nothing and the current Lua request handler will continue executing without interruptions. And the callback function can also decide to terminate everything by calling [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit), for example,
+
+
+    local function my_cleanup()
+        -- custom cleanup work goes here, like cancelling a pending DB transaction
+
+        -- now abort all the "light threads" running in the current request handler
+        ngx.exit(499)
+    end
+
+    local ok, err = ngx.on_abort(my_cleanup)
+    if not ok then
+        ngx.log(ngx.ERR, "failed to register the on_abort callback: ", err)
+        ngx.exit(500)
+    end
+
+
+When [lua_check_client_abort](http://wiki.nginx.org/HttpLuaModule#lua_check_client_abort) is set to `off` (which is the default), then this function call will always return the error message "lua_check_client_abort is off".
+
+According to the current implementation, this function can only be called once in a single request handler; subsequent calls will return the error message "duplicate call".
+
+This API was first introduced in the `v0.7.4` release.
+
+See also [lua_check_client_abort](http://wiki.nginx.org/HttpLuaModule#lua_check_client_abort).
+
+ndk.set_var.DIRECTIVE
+---------------------
+**syntax:** *res = ndk.set_var.DIRECTIVE_NAME*
+
+**context:** *set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua**
+
+This mechanism allows calling other nginx C modules' directives that are implemented by [Nginx Devel Kit](https://github.com/simpl/ngx_devel_kit) (NDK)'s set_var submodule's `ndk_set_var_value`.
+
+For example, the following [HttpSetMiscModule](http://wiki.nginx.org/HttpSetMiscModule) directives can be invoked this way:
+
+* [set_quote_sql_str](http://wiki.nginx.org/HttpSetMiscModule#set_quote_sql_str)
+* [set_quote_pgsql_str](http://wiki.nginx.org/HttpSetMiscModule#set_quote_pgsql_str)
+* [set_quote_json_str](http://wiki.nginx.org/HttpSetMiscModule#set_quote_json_str)
+* [set_unescape_uri](http://wiki.nginx.org/HttpSetMiscModule#set_unescape_uri)
+* [set_escape_uri](http://wiki.nginx.org/HttpSetMiscModule#set_escape_uri)
+* [set_encode_base32](http://wiki.nginx.org/HttpSetMiscModule#set_encode_base32)
+* [set_decode_base32](http://wiki.nginx.org/HttpSetMiscModule#set_decode_base32)
+* [set_encode_base64](http://wiki.nginx.org/HttpSetMiscModule#set_encode_base64)
+* [set_decode_base64](http://wiki.nginx.org/HttpSetMiscModule#set_decode_base64)
+* [set_encode_hex](http://wiki.nginx.org/HttpSetMiscModule#set_encode_base64)
+* [set_decode_hex](http://wiki.nginx.org/HttpSetMiscModule#set_decode_base64)
+* [set_sha1](http://wiki.nginx.org/HttpSetMiscModule#set_encode_base64)
+* [set_md5](http://wiki.nginx.org/HttpSetMiscModule#set_decode_base64)
+
+For instance,
+
+
+    local res = ndk.set_var.set_escape_uri('a/b');
+    -- now res == 'a%2fb'
+
+
+Similarly, the following directives provided by [HttpEncryptedSessionModule](http://wiki.nginx.org/HttpEncryptedSessionModule) can be invoked from within Lua too:
+
+* [set_encrypt_session](http://wiki.nginx.org/HttpEncryptedSessionModule#set_encrypt_session)
+* [set_decrypt_session](http://wiki.nginx.org/HttpEncryptedSessionModule#set_decrypt_session)
+
+This feature requires the [ngx_devel_kit](https://github.com/simpl/ngx_devel_kit) module.
+
+Lua/LuaJIT bytecode support
+===========================
+
+As from the `v0.5.0rc32` release, all `*_by_lua_file` configure directives (such as [content_by_lua_file](http://wiki.nginx.org/HttpLuaModule#content_by_lua_file)) support loading Lua 5.1 and LuaJIT 2.0 raw bytecode files directly.
+
+Please note that the bytecode format used by LuaJIT 2.0 is not compatible with that used by the standard Lua 5.1 interpreter. So if using LuaJIT 2.0 with ngx_lua, LuaJIT compatible bytecode files must be generated as shown:
+
+
+    /path/to/luajit/bin/luajit -b /path/to/input_file.lua /path/to/output_file.luac
+
+
+The `-bg` option can be used to include debug information in the LuaJIT bytecode file:
+
+
+    /path/to/luajit/bin/luajit -bg /path/to/input_file.lua /path/to/output_file.luac
+
+
+Please refer to the official LuaJIT documentation on the `-b` option for more details:
+
+<http://luajit.org/running.html#opt_b>
+
+Similarly, if using the standard Lua 5.1 interpreter with ngx_lua, Lua compatible bytecode files must be generated using the `luac` commandline utility as shown:
+
+
+    luac -o /path/to/output_file.luac /path/to/input_file.lua
+
+
+Unlike as with LuaJIT, debug information is included in standard Lua 5.1 bytecode files by default. This can be striped out by specifying the `-s` option as shown:
+
+
+    luac -s -o /path/to/output_file.luac /path/to/input_file.lua
+
+
+Attempts to load standard Lua 5.1 bytecode files into ngx_lua instances linked to LuaJIT 2.0 or vice versa, will result in an error message, such as that below, being logged into the Nginx `error.log` file:
+
+
+    [error] 13909#0: *1 failed to load Lua inlined code: bad byte-code header in /path/to/test_file.luac
+
+
+Loading bytecode files via the Lua primitives like `require` and `dofile` should always work as expected.
+
+HTTP 1.0 support
+================
+
+The HTTP 1.0 protocol does not support chunked output and requires an explicit `Content-Length` header when the response body is not empty in order to support the HTTP 1.0 keep-alive.
+So when a HTTP 1.0 request is made and the [lua_http10_buffering](http://wiki.nginx.org/HttpLuaModule#lua_http10_buffering) directive is turned `on`, ngx_lua will buffer the
+output of [ngx.say](http://wiki.nginx.org/HttpLuaModule#ngx.say) and [ngx.print](http://wiki.nginx.org/HttpLuaModule#ngx.print) calls and also postpone sending response headers until all the response body output is received.
+At that time ngx_lua can calculate the total length of the body and construct a proper `Content-Length` header to return to the HTTP 1.0 client.
+If the `Content-Length` response header is set in the running Lua code, however, this buffering will be disabled even if the [lua_http10_buffering](http://wiki.nginx.org/HttpLuaModule#lua_http10_buffering) directive is turned `on`.
+
+For large streaming output responses, it is important to disable the [lua_http10_buffering](http://wiki.nginx.org/HttpLuaModule#lua_http10_buffering) directive to minimise memory usage.
+
+Note that common HTTP benchmark tools such as `ab` and `http_load` issue HTTP 1.0 requests by default.
+To force `curl` to send HTTP 1.0 requests, use the `-0` option.
+
+Data Sharing within an Nginx Worker
+===================================
+
+To globally share data among all the requests handled by the same nginx worker process, encapsulate the shared data into a Lua module, use the Lua `require` builtin to import the module, and then manipulate the shared data in Lua. This works because required Lua modules are loaded only once and all coroutines will share the same copy of the module. Note however that Lua global variables WILL NOT persist between requests because of the one-coroutine-per-request isolation design.
+
+Here is a complete small example:
+
+
+    -- mydata.lua
+    module(...)
+ 
+    local data = {
+        dog = 3,
+        cat = 4,
+        pig = 5,
+    }
+ 
+    function get_age(name)
+        return data[name]
+    end
+
+
+and then accessing it from `nginx.conf`:
+
+
+    location /lua {
+        content_by_lua '
+            local mydata = require "mydata"
+            ngx.say(mydata.get_age("dog"))
+        ';
+    }
+
+
+The `mydata` module in this example will only be loaded and run on the first request to the location `/lua`,
+and all subsequent requests to the same nginx worker process will use the reloaded instance of the
+module as well as the same copy of the data in it, until a `HUP` signal is sent to the Nginx master process to force a reload.
+This data sharing technique is essential for high performance Lua applications based on this module.
+
+Note that this data sharing is on a *per-worker* basis and not on a *per-server* basis. That is, when there are multiple nginx worker processes under an Nginx master, data sharing cannot cross the process boundary between these workers.
+
+If server-wide data sharing is required, then use one or more of the following approaches:
+1. Use the [ngx.shared.DICT](http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT) API provided by this module.
+1. Use only a single nginx worker and a single server (this is however not recommended when there is a multi core CPU or multiple CPUs in a single machine).
+1. Use data storage mechanisms such as `memcached`, `redis`, `MySQL` or `PostgreSQL`. [The ngx_openresty bundle](http://openresty.org) associated with this module comes with a set of companion Nginx modules and Lua libraries that provide interfaces with these data storage mechanisms.
+
+Known Issues
+============
+
+TCP socket connect operation issues
+-----------------------------------
+The [tcpsock:connect](http://wiki.nginx.org/HttpLuaModule#tcpsock:connect) method may indicate `success` despite connection failures such as with `Connection Refused` errors. 
+
+However, later attempts to manipulate the cosocket object will fail and return the actual error status message generated by the failed connect operation. 
+
+This issue is due to limitations in the Nginx event model and only appears to affect Mac OS X.
+
+Lua Coroutine Yielding/Resuming
+-------------------------------
+* As the module's predefined Nginx I/O API uses the coroutine yielding/resuming mechanism, user code should not call any Lua modules that use the Lua coroutine mechanism in order to prevent conflicts with the module's predefined Nginx API methods such as [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) (Actually, coroutine modules have been masked off in [content_by_lua](http://wiki.nginx.org/HttpLuaModule#content_by_lua) directives and others). This limitation is significant and work is ongoing on an alternative coroutine implementation that can fit into the Nginx event model to address this. When this is done, it will be possible to use the Lua coroutine mechanism freely as it is in standard Lua implementations.
+* Lua's `dofile` builtin is implemented as a C function in both Lua 5.1 and LuaJIT 2.0 and when [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) is called, [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit) or [ngx.req.read_body](http://wiki.nginx.org/HttpLuaModule#ngx.req.read_body) or similar in the file to be loaded by `dofile`, a coroutine yield across the C function boundary will be initiated. This however is not normally allowed within ngx_lua and will usually result in error messages like `lua handler aborted: runtime error: attempt to yield across C-call boundary`. To avoid this, define a real Lua module and use the Lua `require` builtin instead.
+* As the standard Lua 5.1 interpreter's VM is not fully resumable, the methods [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture), [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi), [ngx.redirect](http://wiki.nginx.org/HttpLuaModule#ngx.redirect), [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), and [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit) cannot be used within the context of a Lua [pcall()](http://www.lua.org/manual/5.1/manual.html#pdf-pcall) or [xpcall()](http://www.lua.org/manual/5.1/manual.html#pdf-xpcall) when the standard Lua 5.1 interpreter is used and the `attempt to yield across metamethod/C-call boundary` error will be produced. Please use LuaJIT 2.0, which supports a fully resumable VM, to avoid this.
+
+Lua Variable Scope
+------------------
+Care should be taken when importing modules and this form should be used:
+
+
+    local xxx = require('xxx')
+
+
+	instead of the old deprecated form:
+
+
+    require('xxx')
+
+
+	If the old form is required, force reload the module for every request by using the `package.loaded.<module>` command:
+
+
+    package.loaded.xxx = nil
+    require('xxx')
+
+
+It is recommended to always place the following piece of code at the end of Lua modules that use the I/O operations to prevent casual use of module-level global variables that are shared among *all* requests:
+
+
+    local class_mt = {
+        -- to prevent use of casual module global variables
+        __newindex = function (table, key, val)
+            error('attempt to write to undeclared variable "' .. key .. '"')
+        end
+    }
+    setmetatable(_M, class_mt)
+
+
+This will guarantee that local variables in the Lua module functions are all declared with the `local` keyword, otherwise a runtime exception will be thrown. It prevents undesirable race conditions while accessing such variables. See [Data Sharing within an Nginx Worker](http://wiki.nginx.org/HttpLuaModule#Data_Sharing_within_an_Nginx_Worker) for the reasons behind this.
+
+Locations Configured by Subrequest Directives of Other Modules
+--------------------------------------------------------------
+The [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) and [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi) directives cannot capture locations that include the [echo_location](http://wiki.nginx.org/HttpEchoModule#echo_location), [echo_location_async](http://wiki.nginx.org/HttpEchoModule#echo_location_async), [echo_subrequest](http://wiki.nginx.org/HttpEchoModule#echo_subrequest), or [echo_subrequest_async](http://wiki.nginx.org/HttpEchoModule#echo_subrequest_async) directives.
+
+
+    location /foo {
+        content_by_lua '
+            res = ngx.location.capture("/bar")
+        ';
+    }
+    location /bar {
+        echo_location /blah;
+    }
+    location /blah {
+        echo "Success!";
+    }
+
+
+
+    $ curl -i http://example.com/foo
+
+
+will not work as expected.
+
+Special PCRE Sequences
+----------------------
+PCRE sequences such as `\d`, `\s`, or `\w`, require special attention because in string literals, the backslash character, `\`, is stripped out by both the Lua language parser and by the Nginx config file parser before processing. So the following snippet will not work as expected:
+
+
+    # nginx.conf
+    ? location /test {
+    ?     content_by_lua '
+    ?         local regex = "\d+"  -- THIS IS WRONG!!
+    ?         local m = ngx.re.match("hello, 1234", regex)
+    ?         if m then ngx.say(m[0]) else ngx.say("not matched!") end
+    ?     ';
+    ? }
+    # evaluates to "not matched!"
+
+
+To avoid this, *double* escape the backslash:
+
+
+    # nginx.conf
+    location /test {
+        content_by_lua '
+            local regex = "\\\\d+"
+            local m = ngx.re.match("hello, 1234", regex)
+            if m then ngx.say(m[0]) else ngx.say("not matched!") end
+        ';
+    }
+    # evaluates to "1234"
+
+
+Here, `\\\\d+` is stripped down to `\\d+` by the Nginx config file parser and this is further stripped down to `\d+` by the Lua language parser before running.
+
+Alternatively, the regex pattern can be presented as a long-bracketed Lua string literal by encasing it in "long brackets", `[[...]]`, in which case backslashes have to only be escaped once for the Nginx config file parser. 
+
+
+    # nginx.conf
+    location /test {
+        content_by_lua '
+            local regex = [[\\d+]]
+            local m = ngx.re.match("hello, 1234", regex)
+            if m then ngx.say(m[0]) else ngx.say("not matched!") end
+        ';
+    }
+    # evaluates to "1234"
+
+
+Here, `[[\\d+]]` is stripped down to `[[\d+]]` by the Nginx config file parser and this is processed correctly.
 
 Note that a longer from of the long bracket, `[=[...]=]`, may be required if the regex pattern contains `[...]` sequences. 
-The `[=[...]=]` form may be used as the default form if desired and it may help with readability if a space is inserted between the long brackets and the regex patterns.

 The possibilities are unlimited as the module allows bringing together various elements within Nginx as well as exposing the power of the Lua language to the user. The module provides the full flexibility of scripting while offering performance levels comparable with native C language programs both in terms of CPU time as well as memory footprint. This is particularly the case when LuaJIT 2.0 is enabled.

 TODO
 ====
 
 Short Term
 ----------
-* add `ignore_resp_headers`, `ignore_resp_body`, and `ignore_resp` options to [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) and ngx.location.capture_multi` methods, to allow micro performance tuning on the user side.

 Changes
 =======
 
-v0.4.1
-------
-
-1 February, 2012
-
-* bugfix: [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit), [ngx.redirect](http://wiki.nginx.org/HttpLuaModule#ngx.redirect), [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec), and [ngx.req.set_uri(uri, true)](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_uri) could return (they should never return as per the documentation). this bug had appeared in ngx_lua v0.3.1rc4 and ngx_openresty 1.0.6.13. thanks [@cyberty](http://weibo.com/cyberty) for reporting it.
-* bugfix: `ngx_http_lua_header_filter_init` was called with an argument which actually accepts none. this could cause compilation errors at least with gcc 4.3.4 as reported in [github issue #80](http://github.com/chaoslawful/lua-nginx-module/issues/80). thanks bigplum (Simon).
-* bugfix: fixed all the warnings from the clang static analyzer.
-* feature: allow use of the `DDEBUG` macro from the outside (via the `-D DDEBUG=1` C compiler opton).
-
-v0.4.0
-------
-
-11 January, 2012
-
-* bugfix: fixed a bug when the both the main request and the subrequest are POST requests with a body: we should not forward the main request's `Content-Length` headers to the user subrequests. thanks 朱峰.
-* feature: implemented the API for reading response headers from within Lua: `value = ngx.header.HEADER`, see [ngx.header.HEADER](http://wiki.nginx.org/HttpLuaModule#ngx.header.HEADER).
-* bugfix: fixed a bug when setting a multi-value response header to a single value (via writing to [ngx.header.HEADER](http://wiki.nginx.org/HttpLuaModule#ngx.header.HEADER)): the single value will be repeated on each old value.
-* bugfix: fixed an issue in [ngx.redirect](http://wiki.nginx.org/HttpLuaModule#ngx.redirect), [ngx.exit](http://wiki.nginx.org/HttpLuaModule#ngx.exit), and [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec): these function calls would be intercepted by Lua `pcall`/`xpcall` because they used Lua exceptions; now they use Lua yield just as [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture). thanks @hugozhu for reporting this.
-* feature: now we also return the `Last-Modified` header (if any) for the subrequest response object. thanks @cyberty and sexybabes.
-* feature: now [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec) supports Lua table as the second args argument value. thanks sexybabes.
-* feature: implemented the [ngx.headers_sent](http://wiki.nginx.org/HttpLuaModule#ngx.headers_sent) API to check if response headers are sent (by ngx_lua). thanks @hugozhu.
-* feature: exposes the CRC-32 API of the Nginx core to the Lua land, in the form of the [ngx.crc32_short](http://wiki.nginx.org/HttpLuaModule#ngx.crc32_short) and [ngx.crc32_long](http://wiki.nginx.org/HttpLuaModule#ngx.crc32_long) methods. thanks @Lance.
-* feature: now for HTTP 1.0 requests, we disable the automatic full buffering mode if the user sets the `Content-Length` response header before sending out the headers. this allows streaming output for HTTP 1.0 requests if the content length can be calculated beforehand. thanks 李子义.
-* bugfix: now we properly support setting the `Cache-Control` response header via the [ngx.header.HEADER](http://wiki.nginx.org/HttpLuaModule#ngx.header.HEADER) interface.
-* bugfix: no longer set header hash to `1`. use the `ngx_hash_key_lc` instead.
-* bugfix: calling [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec) to jump to a named location did not clear the context object of LuaNginxModule properly and might cause evil problems. thanks Nginx User.
-* bugfix: now we explicitly clear all the modules' contexts before dump to named location with [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec).
-* feature: implemented [ngx.req.set_uri](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_uri) and [ngx.req.set_uri_args](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_uri_args) to emulate [HttpRewriteModule](http://wiki.nginx.org/HttpRewriteModule)'s [rewrite](http://wiki.nginx.org/HttpRewriteModule#rewrite) directive. thanks Vladimir Protasov (utros) and Nginx User.
-* bugfix: now we skip rewrite phase Lua handlers altogether if [HttpRewriteModule](http://wiki.nginx.org/HttpRewriteModule)'s [rewrite](http://wiki.nginx.org/HttpRewriteModule#rewrite) directive issue a location re-lookup by changing URIs (but not including `rewrite ... break`). thanks Nginx User.
-* feature: added constant `ngx.HTTP_METHOD_NOT_IMPLEMENTED (501)`. thanks Nginx User.
-* feature: added new Lua functions [ngx.req.read_body](http://wiki.nginx.org/HttpLuaModule#ngx.req.read_body), [ngx.req.discard_body](http://wiki.nginx.org/HttpLuaModule#ngx.req.discard_body), [ngx.req.get_body_data](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_body_data), and [ngx.req.get_body_file](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_body_file). thanks Tzury Bar Yochay for funding the development work.
-* bugfix: fixed hanging issues when using [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec) within [rewrite_by_lua](http://wiki.nginx.org/HttpLuaModule#rewrite_by_lua) and [access_by_lua](http://wiki.nginx.org/HttpLuaModule#access_by_lua). thanks Nginx User for reporting it.
-* feature: added new Lua API [ngx.req.set_body_file](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_body_file). thanks Tzury Bar Yochay for funding the development work.
-* feature: added new Lua API [ngx.req.set_body_data](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_body_data). thanks Tzury Bar Yochay for funding the development work.
-* bugfix: [lua_need_request_body](http://wiki.nginx.org/HttpLuaModule#lua_need_request_body) should not skip requests with methods other than `POST` and `PUT`. thanks Nginx User.
-* bugfix: no longer free request body buffers that are not allocated by ourselves.
-* bugfix: now we allow setting [ngx.var.VARIABLE](http://wiki.nginx.org/HttpLuaModule#ngx.var.VARIABLE) to nil.
-* feature: added new directive [lua_shared_dict](http://wiki.nginx.org/HttpLuaModule#lua_shared_dict).
-* feature: added Lua API for the shm-based dictionary, see [ngx.shared.DICT](http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT).
-* bugfix: fixed spots of -Werror=unused-but-set-variable warning issued by gcc 4.6.0.
-* bugfix: [ndk.set_var.DIRECTIVE](http://wiki.nginx.org/HttpLuaModule#ndk.set_var.DIRECTIVE) had a memory issue and might pass empty argument values to the directive being called. thanks dannynoonan.
-* feature: added the `ctx` option to [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture): you can now specify a custom Lua table to pass to the subrequest as its [ngx.ctx](http://wiki.nginx.org/HttpLuaModule#ngx.ctx). thanks @hugozhu.
-* feature: added the [ngx.encode_args](http://wiki.nginx.org/HttpLuaModule#ngx.encode_args) method to encode a Lua code to a URI query string. thanks 郭颖 (0597虾).
-* feature: [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) and [ngx.exec](http://wiki.nginx.org/HttpLuaModule#ngx.exec) now supports the same Lua args table format as in ngx.encode_args. thanks 郭颖 (0597虾).
-* bugfix: `Cache-Control` header modification might introduce empty value headers when using with the standard HttpHeadersModule.
-* feature: added [ngx.hmac_sha1](http://wiki.nginx.org/HttpLuaModule#ngx.hmac_sha1). thanks drdrxp.
-* docs: documented the long-existent [ngx.md5](http://wiki.nginx.org/HttpLuaModule#ngx.md5) and [ngx.md5_bin](http://wiki.nginx.org/HttpLuaModule#ngx.md5_bin) APIs.
-* docs: massive documentation improvements. thanks Nginx User.
-* feature: added new regex options `j` and `d` to [ngx.re.match](http://wiki.nginx.org/HttpLuaModule#ngx.re.match), [ngx.re.gmatch](http://wiki.nginx.org/HttpLuaModule#ngx.re.gmatch), [ngx.re.sub](http://wiki.nginx.org/HttpLuaModule#ngx.re.sub), and [ngx.re.gsub](http://wiki.nginx.org/HttpLuaModule#ngx.re.gsub) so as to enable the PCRE JIT mode and DFA mode, respectively. thanks @姜大炮 for providing the patch.
-* feature: added options `copy_all_vars` and `vars` to [ngx.location.capture](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture) and [ngx.location.capture_multi](http://wiki.nginx.org/HttpLuaModule#ngx.location.capture_multi). thanks Marcus Clyne for the patch.
-* feature: added new Lua API [ngx.now](http://wiki.nginx.org/HttpLuaModule#ngx.now) to return the current time (including the milliseconds part as the decimal part). thanks 林青.
-* feature: added new Lua API [ngx.update_time](http://wiki.nginx.org/HttpLuaModule#ngx.update_time) to forcibly updating Nginx's time cache.
-* feature: added `wait` boolean argument to [ngx.flush](http://wiki.nginx.org/HttpLuaModule#ngx.flush) to support synchronous flushing: `ngx.flush(true)` will not return until all the data has been flushed into the system send buffer or the send timeout has expired.
-* bugfix: now we check timed out downstream connections in our write event handler.
-* feature: added constant `ngx.HTTP_GATEWAY_TIMEOUT (504)` per Fry-kun in [github issue #73](https://github.com/chaoslawful/lua-nginx-module/issues/73).
-* bugfix: [ngx.var.VARIABLE](http://wiki.nginx.org/HttpLuaModule#ngx.var.VARIABLE) did not evaluate to `nil` when the Nginx variable's `valid` flag is `0`.
-* bugfix: there were various places where we did not check the pointer returned by the memory allocator.
-* bugfix: [ngx.req.set_header](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_header) and [ngx.req.clear_header](http://wiki.nginx.org/HttpLuaModule#ngx.req.clear_header) did not handle the `Accept-Encoding` request headers properly. thanks 天街夜色.
-* bugfix: [ngx.req.set_header](http://wiki.nginx.org/HttpLuaModule#ngx.req.set_header) might cause invalid memory reads because Nginx request header values must be `NULL` terminated. thanks Maxim Dounin.
-* bugfix: removing builtin headers via [ngx.req.clear_header](http://wiki.nginx.org/HttpLuaModule#ngx.req.clear_header) and its equivalent in huge request headers with 20+ entries could result in data loss. thanks Chris Dumoulin.
-* bugfix: [ngx.req.get_uri_args](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_uri_args) and [ngx.req.get_post_args](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_post_args) now only parse up to `100` arguments by default. but one can specify the optional argument to these two methods to specify a custom maximum number of args. thanks Tzury Bar Yochay for reporting this.
-* bugfix: [ngx.req.get_headers](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_headers) now only parse up to `100` request headers by default. but one can specify the optional argument to this method to specify a custom maximum number of headers.

-v0.3.0
-------
-
-September 02, 2011
-
-**New features**
-
-* added the [header_filter_by_lua](http://wiki.nginx.org/HttpLuaModule#header_filter_by_lua) and [header_filter_by_lua_file](http://wiki.nginx.org/HttpLuaModule#header_filter_by_lua_file) directives. thanks Liseen Wan (万珣新).
-* implemented the PCRE regex API for Lua: [ngx.re.match](http://wiki.nginx.org/HttpLuaModule#ngx.re.match), [ngx.re.gmatch](http://wiki.nginx.org/HttpLuaModule#ngx.re.gmatch), [ngx.re.sub](http://wiki.nginx.org/HttpLuaModule#ngx.re.sub), and [ngx.re.gsub](http://wiki.nginx.org/HttpLuaModule#ngx.re.gsub).
-* now we add the `ngx` and `ndk` table into `package.loaded` such that the user can write `local ngx = require 'ngx'` and `local ndk = require 'ndk'`. thanks @Lance.
-* added new directive [lua_regex_cache_max_entries](http://wiki.nginx.org/HttpLuaModule#lua_regex_cache_max_entries) to control the upper limit of the worker-process-level compiled-regex cache enabled by the `o` regex option.
-* implemented the special [ngx.ctx](http://wiki.nginx.org/HttpLuaModule#ngx.ctx) Lua table for user programmers to store per-request Lua context data for their applications. thanks 欧远宁 for suggesting this feature.
-* now [ngx.print](http://wiki.nginx.org/HttpLuaModule#ngx.print) and [ngx.say](http://wiki.nginx.org/HttpLuaModule#ngx.say) allow (nested) array-like table arguments. the array elements in them will be sent piece by piece. this will avoid string concatenation for templating engines like [ltp](http://www.savarese.com/software/ltp/).
-* implemented the [ngx.req.get_post_args](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_post_args) method for fetching url-encoded POST query arguments from within Lua.
-* implemented the [ngx.req.get_uri_args](http://wiki.nginx.org/HttpLuaModule#ngx.req.get_uri_args) method to fetch parsed URL query arguments from within Lua. thanks Bertrand Mansion (golgote).
-* added new function [ngx.parse_http_time](http://wiki.nginx.org/HttpLuaModule#ngx.parse_http_time), thanks James Hurst.
-* now we allow Lua boolean and `nil` values in arguments to [ngx.say](http://wiki.nginx.org/HttpLuaModule#ngx.say), [ngx.print](http://wiki.nginx.org/HttpLuaModule#ngx.print), [ngx.log](http://wiki.nginx.org/HttpLuaModule#ngx.log) and [print](http://wiki.nginx.org/HttpLuaModule#print).
-* added support for user C macros `LUA_DEFAULT_PATH` and `LUA_DEFAULT_CPATH`. for now we can only define them in `ngx_lua`'s `config` file because nginx `configure`'s `--with-cc-opt` option hates values with double-quotes in them. sigh. This feature is used by [The ngx_openresty bundle](http://openresty.org) to bundle third party Lua libraries.
-
-**Bug fixes**
-
-* worked-around the "stack overflow" issue while using `luarocks.loader` and disabling [lua_code_cache](http://wiki.nginx.org/HttpLuaModule#lua_code_cache), as described as github issue #27. thanks Patrick Crosby.
-* fixed the `zero size buf in output` alert while combining [lua_need_request_body](http://wiki.nginx.org/HttpLuaModule#lua_need_request_body) on + [access_by_lua](http://wiki.nginx.org/HttpLuaModule#access_by_lua)/[rewrite_by_lua](http://wiki.nginx.org/HttpLuaModule#rewrite_by_lua) + [proxy_pass](http://wiki.nginx.org/HttpProxyModule#proxy_pass)/[fastcgi_pass](http://wiki.nginx.org/HttpFcgiModule#fastcgi_pass). thanks Liseen Wan (万珣新).
-* fixed issues with HTTP 1.0 HEAD requests.
-* made setting `ngx.header.HEADER` after sending out response headers throw out a Lua exception to help debugging issues like github issue #49. thanks Bill Donahue (ikhoyo).
-* fixed an issue regarding defining global variables in C header files: we should have defined the global `ngx_http_lua_exception` in a single compilation unit. thanks @姜大炮.

-The Lua interpreter or LuaJIT instance is shared across all the requests in a single nginx worker process but request contexts are segregated using lightweight Lua coroutines. 
-Loaded Lua modules persist at the nginx worker process level resulting in a small memory footprint even when under heavy loads.
+At least the following Lua libraries and Nginx modules can be used with this ngx_lua module:

+
+Almost all the Nginx modules can be used with this ngx_lua module by means of [[#ngx.location.capture|ngx.location.capture]] or [[#ngx.location.capture_multi|ngx.location.capture_multi]] but it is recommended to use those <code>lua-resty-*</code> libraries instead of creating subrequests to access the Nginx upstream modules because the former is usually much more flexible and memory-efficient.

+
+Runs the Lua code specified by the argument <code><lua-script-str></code> on the global Lua VM level when the Nginx master process (if any) is loading the Nginx config file.
+
+When Nginx receives the <code>HUP</code> signal and starts reloading the config file, the Lua VM will also be re-created and <code>init_by_lua</code> will run again on the new Lua VM.
+
+Usually you can register (true) Lua global variables or pre-load Lua modules at server start-up by means of this hook. Here is an example for pre-loading Lua modules:
+
+<geshi lang="nginx">
+    init_by_lua 'require "cjson"';
+
+    server {
+        location = /api {
+            content_by_lua '
+                ngx.say(cjson.encode({dog = 5, cat = 6}))
+            ';
+        }
+    }
+</geshi>
+
+You can also initialize the [[#lua_shared_dict|lua_shared_dict]] shm storage at this phase. Here is an example for this:
+
+<geshi lang="nginx">
+    lua_shared_dict dogs 1m;
+
+    init_by_lua '
+        local dogs = ngx.shared.dogs;
+        dogs:set("Tom", 56)
+    ';
+
+    server {
+        location = /api {
+            content_by_lua '
+                local dogs = ngx.shared.dogs;
+                ngx.say(dogs:get("Tom"))
+            ';
+        }
+    }
+</geshi>
+
+But note that, the [[#lua_shared_dict|lua_shared_dict]]'s shm storage will not be cleared through a config reload (via the <code>HUP</code> signal, for example). So if you do ''not'' want to re-initialize the shm storage in your <code>init_by_lua</code> code in this case, then you just need to set a custom flag in the shm storage and always check the flag in your <code>init_by_lua</code> code.
+
+Because the Lua code in this context runs before Nginx forks its worker processes (if any), data or code loaded here will enjoy the [http://en.wikipedia.org/wiki/Copy-on-write Copy-on-write (COW)] feature provided by many operating systems among all the worker processes, thus saving a lot of memory.
+
+Only a small set of the [[#Nginx API for Lua|Nginx API for Lua]] is supported in this context:
+
+* Logging APIs: [[#ngx.log|ngx.log]] and [[#print|print]],
+* Shared Dictionary API: [[#ngx.shared.DICT|ngx.shared.DICT]].
+
+More Nginx APIs for Lua may be supported in this context upon future user requests.
+
+Basically you can safely use Lua libraries that do blocking I/O in this very context because blocking the master process during server start-up is completely okay. Even the Nginx core does blocking I/O (at least on resolving upstream's host names) at the configure-loading phase.
+
+You should be very careful about potential security vulnerabilities in your Lua code registered in this context because the Nginx master process is often run under the <code>root</code> account.

+
+Uses Lua code specified in <code><lua-script-str></code> to define an output body filter.
+
+The input data chunk is passed via [[#ngx.arg|ngx.arg]][1] (as a Lua string value) and the "eof" flag indicating the end of the response body data stream is passed via [[#ngx.arg|ngx.arg]][2] (as a Lua boolean value).
+
+Behind the scene, the "eof" flag is just the <code>last_buf</code> flag of the nginx chain link buffers. And in the context of an Nginx subrequest, there is no "eof" flag at all, due to the underlying limitation in the Nginx core.
+
+The output data stream can be aborted immediately by running the following Lua statement:
+
+<geshi lang="lua">
+    return ngx.ERROR
+</geshi>
+
+This will truncate the response body and usually result in incomplete and also invalid responses.
+
+The Lua code can pass its own modified version of the input data chunk to the downstream Nginx output body filters by overriding [[#ngx.arg|ngx.arg]][1] with a Lua string or a Lua table of strings. For example, to transform all the lowercase letters in the response body, we can just write:
+
+<geshi lang="nginx">
+    location / {
+        proxy_pass http://mybackend;
+        body_filter_by_lua 'ngx.arg[1] = string.upper(ngx.arg[1])';
+    }
+</geshi>
+
+When setting <code>nil</code> or an empty Lua string value to <code>ngx.arg[1]</code>, no data chunk will be passed to the downstream Nginx output filters at all.
+
+Likewise, new "eof" flag can also be specified by setting a boolean value to [[#ngx.arg|ngx.arg]][2]. For example,
+
+<geshi lang="nginx">
+    location /t {
+        echo hello world;
+        echo hiya globe;
+
+        body_filter_by_lua '
+            local chunk = ngx.arg[1]
+            if string.match(chunk, "hello") then
+                ngx.arg[2] = true  -- new eof
+                return
+            end
+
+            -- just throw away any remaining chunk data
+            ngx.arg[1] = nil
+        ';
+    }
+</geshi>
+
+Then <code>GET /t</code> will just return the output
+
+<geshi lang="text">
+    hello world
+</geshi>
+
+That is, when the body filter sees a chunk containing the word "hello", then it will set the "eof" flag to true immediately, resulting in truncated but still valid responses.
+
+When the Lua code may change the length of the response body, then it is required to always clear out the <code>Content-Length</code> response header (if any) in a header filter to enforce streaming output, as in
+
+<geshi lang="nginx">
+    location /foo {
+        # fastcgi_pass/proxy_pass/...
+
+        header_filter_by_lua 'ngx.header.content_length = nil';

+The <code><time></code> argument can be an integer, with an optional time unit, like <code>s</code> (second), <code>ms</code> (millisecond), <code>m</code> (minute). The default time unit is <code>s</code>, i.e., "second". The default setting is <code>60s</code>.

+Enables or disables response caching for HTTP 1.0 (or older) requests. This buffering mechanism is mainly used for HTTP 1.0 keep-alive which replies on a proper <code>Content-Length</code> response header.
+
+If the Lua code explicitly sets a <code>Content-Length</code> response header before sending the headers (either explicitly via [[#ngx.send_headers|ngx.send_headers]] or implicitly via the first [[#ngx.say|ngx.say]] or [[#ngx.print|ngx.print]] call).
+
+To output very large response data in a streaming fashion (via the [[#ngx.flush|ngx.flush]] call, for example), this directive MUST be turned off to minimize memory usage.

+
+'''default:''' ''lua_check_client_abort off''
+
+'''context:''' ''http, server, location, location-if''
+
+This directive controls whether to check for premature client connection abortion.
+
+When this directive is turned on, the ngx_lua module will monitor the premature connection close event on the downstream connections. And when there is such an event, it will call the user Lua function callback (registered by [[#ngx.on_abort|ngx.on_abort]]) or just stop and clean up all the Lua "light threads" running in the current request's request handler when there is no user callback function registered.
+
+According to the current implementation, however, if the client closes the connection before the Lua code finishes reading the request body data via [[#ngx.req.socket|ngx.req.socket]], then ngx_lua will neither stop all the running "light threads" nor call the user callback (if [[#ngx.on_abort|ngx.on_abort]] has been called). Instead, the reading operation on [[#ngx.req.socket|ngx.req.socket]] will just return the error message "client aborted" as the second return value (the first return value is surely <code>nil</code>).
+
+When TCP keepalive is disabled, it is relying on the client side to close the socket gracefully (by sending a <code>FIN</code> packet or something like that). For (soft) real-time web applications, it is highly recommended to configure the [http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/overview.html TCP keepalive] support in your system's TCP stack implementation in order to detect "half-open" TCP connections in time.
+
+For example, on Linux, you can configure the standard [[HttpCoreModule#listen|listen]] directive in your <code>nginx.conf</code> file like this:
+
+<geshi lang="nginx">
+    listen 80 so_keepalive=2s:2s:8;
+</geshi>
+
+On FreeBSD, you can only tune the system-wide configuration for TCP keepalive, for example:
+
+    # sysctl net.inet.tcp.keepintvl=2000
+    # sysctl net.inet.tcp.keepidle=2000
+
+This directive was first introduced in the <code>v0.7.4</code> release.
+
+See also [[#ngx.on_abort|ngx.on_abort]].
+
+= Nginx API for Lua =
+== Introduction ==
+The various <code>*_by_lua</code> and <code>*_by_lua_file</code> configuration directives serve as gateways to the Lua API within the <code>nginx.conf</code> file. The Nginx Lua API described below can only be called within the user Lua code run in the context of these configuration directives.
+
+The API is exposed to Lua in the form of two standard packages <code>ngx</code> and <code>ndk</code>. These packages are in the default global scope within ngx_lua and are always available within ngx_lua directives.
+
+The packages can be introduced into external Lua modules like this:
+
+<geshi lang="lua">
+    local say = ngx.say
+
+    module(...)
+
+    function foo(a) 
+        say(a) 
+    end
+</geshi>
+
+Use of the [http://www.lua.org/manual/5.1/manual.html#pdf-package.seeall package.seeall] flag is strongly discouraged due to its various bad side-effects.
+
+It is also possible to directly require the packages in external Lua modules:
+
+<geshi lang="lua">
+    local ngx = require "ngx"
+    local ndk = require "ndk"
+</geshi>
+
+The ability to require these packages was introduced in the <code>v0.2.1rc19</code> release.
+
+Network I/O operations in user code should only be done through the Nginx Lua API calls as the Nginx event loop may be blocked and performance drop off dramatically otherwise. Disk operations with relatively small amount of data can be done using the standard Lua <code>io</code> library but huge file reading and writing should be avoided wherever possible as they may block the Nginx process significantly. Delegating all network and disk I/O operations to Nginx's subrequests (via the [[#ngx.location.capture|ngx.location.capture]] method and similar) is strongly recommended for maximum performance.
+
+== ngx.arg ==
+'''syntax:''' ''val = ngx.arg[index]''
+
+'''context:''' ''set_by_lua*, body_filter_by_lua*''
+
+When this is used in the context of the [[#set_by_lua|set_by_lua]] or [[#set_by_lua_file|set_by_lua_file]] directives, this table is read-only and holds the input arguments to the config directives:
+
+<geshi lang="lua">
+    value = ngx.arg[n]
+</geshi>
+
+Here is an example
+
+<geshi lang="nginx">
+    location /foo {
+        set $a 32;
+        set $b 56;
+ 
+        set_by_lua $res
+            'return tonumber(ngx.arg[1]) + tonumber(ngx.arg[2])'
+            $a $b;
+ 
+        echo $sum;
+    }
+</geshi>
+
+that writes out <code>88</code>, the sum of <code>32</code> and <code>56</code>.
+
+When this table is used in the context of [[#body_filter_by_lua|body_filter_by_lua]] or [[#body_filter_by_lua_file|body_filter_by_lua_file]], the first element holds the input data chunk to the output filter code and the second element holds the boolean flag for the "eof" flag indicating the end of the whole output data stream.
+
+The data chunk and "eof" flag passed to the downstream Nginx output filters can also be overridden by assigning values directly to the corresponding table elements. When setting <code>nil</code> or an empty Lua string value to <code>ngx.arg[1]</code>, no data chunk will be passed to the downstream Nginx output filters at all.
+
+== ngx.var.VARIABLE ==
+'''syntax:''' ''ngx.var.VAR_NAME''
+
+'''context:''' ''set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*''
+
+Read and write Nginx variable values.
+
+<geshi lang="nginx">
+    value = ngx.var.some_nginx_variable_name
+    ngx.var.some_nginx_variable_name = value
+</geshi>
+
+Note that only already defined nginx variables can be written to.
+For example:
+
+<geshi lang="nginx">
+    location /foo {
+        set $my_var ''; # this line is required to create $my_var at config time
+        content_by_lua '
+            ngx.var.my_var = 123;
+            ...
+        ';
+    }
+</geshi>
+
+That is, nginx variables cannot be created on-the-fly.
+
+Some special nginx variables like <code>$args</code> and <code>$limit_rate</code> can be assigned a value,
+some are not, like <code>$arg_PARAMETER</code>.
+
+Nginx regex group capturing variables <code>$1</code>, <code>$2</code>, <code>$3</code>, and etc, can be read by this
+interface as well, by writing <code>ngx.var[1]</code>, <code>ngx.var[2]</code>, <code>ngx.var[3]</code>, and etc.
+
+Setting <code>ngx.var.Foo</code> to a <code>nil</code> value will unset the <code>$Foo</code> Nginx variable. 
+
+<geshi lang="lua">
+    ngx.var.args = nil
+</geshi>
+
+'''WARNING''' When reading from an Nginx variable, Nginx will allocate memory in the per-request memory pool which is freed only at request termination. So when you need to read from an Nginx variable repeatedly in your Lua code, cache the Nginx variable value to your own Lua variable, for example,
+
+<geshi lang="lua">
+    local val = ngx.var.some_var
+    --- use the val repeatedly later
+</geshi>
+
+to prevent (temporary) memory leaking within the current request's lifetime.

-'''NOTE: This mechanism behaves differently when code cache is turned off and should be considered a DIRTY TRICK. Note that backward compatibility is NOT guaranteed and that there may be other undesirable consequences. A new data sharing mechanism will be designed later.'''
+'''WARNING''' Be careful when calling this method on dictionaries with a really huge number of keys. This method may lock the dictionary for quite a while and block all the nginx worker processes that are trying to access the dictionary.
 
-To globally share data among all the requests handled by the same nginx worker process, encapsulate the shared data into a Lua module, use the Lua <code>require</code> builtin to import the module, and then manipulate the shared data in Lua. This works because required Lua modules are loaded only once and all coroutines will share the same copy of the module.

-and all subsequent requests to the same nginx worker process will use the reloaded instance of the

+It is intended to be compatible with the UDP API of the [http://w3.impa.br/~diego/software/luasocket/udp.html LuaSocket] library but is 100% nonblocking out of the box.
 
-Note that this data sharing is on a ''per-worker'' basis and not on a ''per-server' basis'. That is, when there are multiple nginx worker processes under an Nginx master, data sharing cannot cross the process boundary between these workers.

-== Lua Coroutine Yielding/Resuming ==
-* As the module's predefined Nginx I/O API uses the coroutine yielding/resuming mechanism, user code should not call any Lua modules that use the Lua coroutine mechanism in order to prevent conflicts with the module's predefined Nginx API methods such as [[#ngx.location.capture|ngx.location.capture]] (Actually, coroutine modules have been masked off in [[#content_by_lua|content_by_lua]] directives and others). This limitation is significant and work is ongoing on an alternative coroutine implementation that can fit into the Nginx event model to address this. When this is done, it will be possible to use the Lua coroutine mechanism freely as it is in standard Lua implementations.
-* Lua's <code>dofile</code> builtin is implemented as a C function in both Lua 5.1 and LuaJIT 2.0 and when [[#ngx.location.capture|ngx.location.capture]] is called, [[#ngx.exec|ngx.exec]], [[#ngx.exit|ngx.exit]] or [[#ngx.req.read_body|ngx.req.read_body]] or similar in the file to be loaded by <code>dofile</code>, a coroutine yield across the C function boundary will be initiated. This however is not allowed within ngx_lua and will usually result in error messages like <code>lua handler aborted: runtime error: attempt to yield across C-call boundary</code>. To avoid this, define a real Lua module and use the Lua <code>require</code> builtin instead.
-* Because the standard Lua 5.1 interpreter's VM is not fully resumable, the methods [[#ngx.location.capture|ngx.location.capture]], [[#ngx.location.capture_multi|ngx.location.capture_multi]], [[#ngx.redirect|ngx.redirect]], [[#ngx.exec|ngx.exec]], and [[#ngx.exit|ngx.exit]] cannot be used within the context of a Lua [http://www.lua.org/manual/5.1/manual.html#pdf-pcall pcall()] or [http://www.lua.org/manual/5.1/manual.html#pdf-xpcall xpcall()] when the standard Lua 5.1 interpreter is used and the <code>attempt to yield across metamethod/C-call boundary</code> error will be produced. Please use LuaJIT 2.0, which supports a fully resumable VM, to avoid this.

-== Lua Variable Scope ==
-Care should be taken when importing modules and this form should be used:
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
 
-<geshi lang="nginx">
-        local xxx = require('xxx')
-</geshi>
+Attempts to connect a UDP socket object to a remote server or to a datagram unix domain socket file. Because the datagram protocol is actually connection-less, this method does not really establish a "connection", but only just set the name of the remote peer for subsequent read/write operations.
 
-: instead of the old deprecated form:
+Both IP addresses and domain names can be specified as the <code>host</code> argument. In case of domain names, this method will use Nginx core's dynamic resolver to parse the domain name without blocking and it is required to configure the [[HttpCoreModule#resolver|resolver]] directive in the <code>nginx.conf</code> file like this:
 
 <geshi lang="nginx">
-        require('xxx')
+    resolver 8.8.8.8;  # use Google's public DNS nameserver
 </geshi>
 
-: If the old form is required, force reload the module for every request by using the <code>package.loaded.<module></code> command:
+If the nameserver returns multiple IP addresses for the host name, this method will pick up one randomly.
 
-<geshi lang="nginx">
-        package.loaded.xxx = nil
-        require('xxx')
-</geshi>
+In case of error, the method returns <code>nil</code> followed by a string describing the error. In case of success, the method returns <code>1</code>.
 
-It is recommended to always place the following piece of code at the end of Lua modules that use the [[#ngx.location.capture|ngx.location.capture]] or [[#ngx.location.capture_multi|ngx.location.capture_multi]] directives to prevent casual use of module-level global variables that are shared among ''all'' requests:
+Here is an example for connecting to a UDP (memcached) server:
 
 <geshi lang="nginx">
-    getmetatable(foo.bar).__newindex = function (table, key, val)
-        error('Attempt to write to undeclared variable "' .. key .. '": '
-                .. debug.traceback())
-    end
-</geshi>
-
-Assuming the current Lua module is named <code>foo.bar</code>, this will guarantee that local variables in module <code>foo.bar</code> functions have been declared as "local". It prevents undesirable race conditions while accessing such variables. See [[#Data_Sharing_within_an_Nginx_Worker|Data Sharing within an Nginx Worker]] for the reasons behind this.
-
-== Locations With [[HttpEchoModule]] Directives ==
-The [[#ngx.location.capture|ngx.location.capture]] and [[#ngx.location.capture_multi|ngx.location.capture_multi]] directives cannot capture locations that include the [[HttpEchoModule#echo_location|echo_location]], [[HttpEchoModule#echo_location_async|echo_location_async]], [[HttpEchoModule#echo_subrequest|echo_subrequest]], or [[HttpEchoModule#echo_subrequest_async|echo_subrequest_async]] directives.
+    location /test {
+        resolver 8.8.8.8;
 
-<geshi lang="nginx">

-            res = ngx.location.capature("/bar")
+            local sock = ngx.socket.udp()
+            local ok, err = sock:setpeername("my.memcached.server.domain", 11211)
+            if not ok then
+                ngx.say("failed to connect to memcached: ", err)
+                return
+            end
+            ngx.say("successfully connected to memcached!")
+            sock:close()

+    local ok, err = sock:setpeername("unix:/tmp/some-datagram-service.sock")
+    if not ok then
+        ngx.say("failed to connect to the datagram unix domain socket: ", err)
+        return
+    end
 </geshi>
 
-will not work as expected.
+assuming the datagram service is listening on the unix domain socket file <code>/tmp/some-datagram-service.sock</code>.
 
-== Special PCRE Sequences ==
-PCRE sequences such as <code>\d</code>, <code>\s</code>, or <code>\w</code>, require special attention because in string literals, the backslash character, <code>\</code>, is stripped out by both the Lua language parser and by the Nginx config file parser before processing. So the following snippet will not work as expected:
+Calling this method on an already connected socket object will cause the original connection to be closed first.
 
-<geshi lang="nginx">
-    # nginx.conf
-    ? location /test {
-    ?     content_by_lua '
-    ?         local regex = "\d+"  -- THIS IS WRONG!!
-    ?         local m = ngx.re.match("hello, 1234", regex)
-    ?         if m then ngx.say(m[0]) else ngx.say("not matched!") end
-    ?     ';
-    ? }
-    # evaluates to "not matched!"
-</geshi>
+This method was first introduced in the <code>v0.5.7</code> release.
 
-To avoid this, ''double'' escape the backslash:
+== udpsock:send ==
+'''syntax:''' ''ok, err = udpsock:send(data)''
 
-<geshi lang="nginx">
-    # nginx.conf
-    location /test {
-        content_by_lua '
-            local regex = "\\\\d+"
-            local m = ngx.re.match("hello, 1234", regex)
-            if m then ngx.say(m[0]) else ngx.say("not matched!") end
-        ';
-    }
-    # evaluates to "1234"
-</geshi>
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
 
-Here, <code>\\\\d+</code> is stripped down to <code>\\d+</code> by the Nginx config file parser and this is further stripped down to <code>\d+</code> by the Lua language parser before running.
+Sends data on the current UDP or datagram unix domain socket object.
 
-Alternatively, the regex pattern can be presented as a long-bracketed lua string literal by encasing it in "long brackets", <code>&#91;[...]]</code>, in which case backslashes have to only be escaped once for the Nginx config file parser. 
+In case of success, it returns <code>1</code>. Otherwise, it returns <code>nil</code> and a string describing the error.
 
-<geshi lang="nginx">
-    # nginx.conf
-    location /test {
-        content_by_lua '
-            local regex = [[\\d+]]
-            local m = ngx.re.match("hello, 1234", regex)
-            if m then ngx.say(m[0]) else ngx.say("not matched!") end
-        ';
-    }
-    # evaluates to "1234"
-</geshi>
+The input argument <code>data</code> can either be a Lua string or a (nested) Lua table holding string fragments. In case of table arguments, this method will copy all the string elements piece by piece to the underlying Nginx socket send buffers, which is usually optimal than doing string concatenation operations on the Lua land.
 
-Here, <code>&#91;[\\d+]]</code> is stripped down to <code>&#91;[\d+]]</code> by the Nginx config file parser and this is processed correctly.
+This feature was first introduced in the <code>v0.5.7</code> release.
 
-Note that a longer from of the long bracket, <code>[=[...]=]</code>, may be required if the regex pattern contains <code>&#91;...]</code> sequences. 
-The <code>[=[...]=]</code> form may be used as the default form if desired and it may help with readability if a space is inserted between the long brackets and the regex patterns.
+== udpsock:receive ==
+'''syntax:''' ''data, err = udpsock:receive(size?)''
 
-<geshi lang="nginx">
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Receives data from the UDP or datagram unix domain socket object with an optional receive buffer size argument, <code>size</code>.
+
+This method is a synchronous operation and is 100% nonblocking.
+
+In case of success, it returns the data received; in case of error, it returns <code>nil</code> with a string describing the error.
+
+If the <code>size</code> argument is specified, then this method will use this size as the receive buffer size. But when this size is greater than <code>8192</code>, then <code>8192</code> will be used instead.
+
+If no argument is specified, then the maximal buffer size, <code>8192</code> is assumed.
+
+Timeout for the reading operation is controlled by the [[#lua_socket_read_timeout|lua_socket_read_timeout]] config directive and the [[#udpsock:settimeout|settimeout]] method. And the latter takes priority. For example:
+
+<geshi lang="lua">
+    sock:settimeout(1000)  -- one second timeout
+    local data, err = sock:receive()
+    if not data then
+        ngx.say("failed to read a packet: ", data)
+        return
+    end
+    ngx.say("successfully read a packet: ", data)
+</geshi>
+
+It is important here to call the [[#udpsock:settimeout|settimeout]] method ''before'' calling this method.
+
+This feature was first introduced in the <code>v0.5.7</code> release.
+
+== udpsock:close ==
+'''syntax:''' ''ok, err = udpsock:close()''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Closes the current UDP or datagram unix domain socket. It returns the <code>1</code> in case of success and returns <code>nil</code> with a string describing the error otherwise.
+
+Socket objects that have not invoked this method (and associated connections) will be closed when the socket object is released by the Lua GC (Garbage Collector) or the current client HTTP request finishes processing.
+
+This feature was first introduced in the <code>v0.5.7</code> release.
+
+== udpsock:settimeout ==
+'''syntax:''' ''udpsock:settimeout(time)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Set the timeout value in milliseconds for subsequent socket operations (like [[#udpsock:receive|receive]]).
+
+Settings done by this method takes priority over those config directives, like [[#lua_socket_read_timeout|lua_socket_read_timeout]].
+
+This feature was first introduced in the <code>v0.5.7</code> release.
+
+== ngx.socket.tcp ==
+'''syntax:''' ''tcpsock = ngx.socket.tcp()''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Creates and returns a TCP or stream-oriented unix domain socket object (also known as one type of the "cosocket" objects). The following methods are supported on this object:
+
+* [[#tcpsock:connect|connect]]
+* [[#tcpsock:send|send]]
+* [[#tcpsock:receive|receive]]
+* [[#tcpsock:close|close]]

+* [[#tcpsock:receiveuntil|receiveuntil]]
+* [[#tcpsock:setkeepalive|setkeepalive]]
+* [[#tcpsock:getreusedtimes|getreusedtimes]]
+
+It is intended to be compatible with the TCP API of the [http://w3.impa.br/~diego/software/luasocket/tcp.html LuaSocket] library but is 100% nonblocking out of the box. Also, we introduce some new APIs to provide more functionalities.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.

+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Attempts to connect a TCP socket object to a remote server or to a stream unix domain socket file without blocking.
+
+Before actually resolving the host name and connecting to the remote backend, this method will always look up the connection pool for matched idle connections created by previous calls of this method (or the [[#ngx.socket.connect|ngx.socket.connect]] function).
+
+Both IP addresses and domain names can be specified as the <code>host</code> argument. In case of domain names, this method will use Nginx core's dynamic resolver to parse the domain name without blocking and it is required to configure the [[HttpCoreModule#resolver|resolver]] directive in the <code>nginx.conf</code> file like this:
+
+<geshi lang="nginx">
+    resolver 8.8.8.8;  # use Google's public DNS nameserver
+</geshi>
+
+If the nameserver returns multiple IP addresses for the host name, this method will pick up one randomly.
+
+In case of error, the method returns <code>nil</code> followed by a string describing the error. In case of success, the method returns <code>1</code>.
+
+Here is an example for connecting to a TCP server:
+
+<geshi lang="nginx">
+    location /test {
+        resolver 8.8.8.8;
+
+        content_by_lua '

+            local ok, err = sock:connect("www.google.com", 80)
+            if not ok then
+                ngx.say("failed to connect to google: ", err)
+                return
+            end
+            ngx.say("successfully connected to google!")
+            sock:close()
+        ';
+    }
+</geshi>
+
+Connecting to a Unix Domain Socket file is also possible:
+
+<geshi lang="lua">
+    local sock = ngx.socket.tcp()
+    local ok, err = sock:connect("unix:/tmp/memcached.sock")
+    if not ok then
+        ngx.say("failed to connect to the memcached unix domain socket: ", err)
+        return
+    end
+</geshi>
+
+assuming memcached (or something else) is listening on the unix domain socket file <code>/tmp/memcached.sock</code>.
+
+Timeout for the connecting operation is controlled by the [[#lua_socket_connect_timeout|lua_socket_connect_timeout]] config directive and the [[#tcpsock:settimeout|settimeout]] method. And the latter takes priority. For example:
+
+<geshi lang="lua">
+    local sock = ngx.socket.tcp()
+    sock:settimeout(1000)  -- one second timeout
+    local ok, err = sock:connect(host, port)
+</geshi>
+
+It is important here to call the [[#tcpsock:settimeout|settimeout]] method ''before'' calling this method.
+
+Calling this method on an already connected socket object will cause the original connection to be closed first.
+
+An optional Lua table can be specified as the last argument to this method to specify various connect options:
+
+* <code>pool</code>
+: specify a custom name for the connection pool being used. If omitted, then the connection pool name will be generated from the string template <code>"<host>:<port>"</code> or <code>"<unix-socket-path>"</code>.
+
+The support for the options table argument was first introduced in the <code>v0.5.7</code> release.
+
+This method was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:send ==
+'''syntax:''' ''bytes, err = tcpsock:send(data)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Sends data without blocking on the current TCP or Unix Domain Socket connection.
+
+This method is a synchronous operation that will not return until ''all'' the data has been flushed into the system socket send buffer or an error occurs.
+
+In case of success, it returns the total number of bytes that have been sent. Otherwise, it returns <code>nil</code> and a string describing the error.
+
+The input argument <code>data</code> can either be a Lua string or a (nested) Lua table holding string fragments. In case of table arguments, this method will copy all the string elements piece by piece to the underlying Nginx socket send buffers, which is usually optimal than doing string concatenation operations on the Lua land.
+
+Timeout for the sending operation is controlled by the [[#lua_socket_send_timeout|lua_socket_send_timeout]] config directive and the [[#tcpsock:settimeout|settimeout]] method. And the latter takes priority. For example:
+
+<geshi lang="lua">
+    sock:settimeout(1000)  -- one second timeout
+    local bytes, err = sock:send(request)
+</geshi>
+
+It is important here to call the [[#tcpsock:settimeout|settimeout]] method ''before'' calling this method.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:receive ==
+'''syntax:''' ''data, err, partial = tcpsock:receive(size)''
+
+'''syntax:''' ''data, err, partial = tcpsock:receive(pattern?)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Receives data from the connected socket according to the reading pattern or size.
+
+This method is a synchronous operation just like the [[#tcpsock:send|send]] method and is 100% nonblocking.
+
+In case of success, it returns the data received; in case of error, it returns <code>nil</code> with a string describing the error and the partial data received so far.
+
+If a number-like argument is specified (including strings that look like numbers), then it is interpreted as a size. This method will not return until it reads exactly this size of data or an error occurs.
+
+If a non-number-like string argument is specified, then it is interpreted as a "pattern". The following patterns are supported:
+
+* <code>'*a'</code>: reads from the socket until the connection is closed. No end-of-line translation is performed;
+* <code>'*l'</code>: reads a line of text from the socket. The line is terminated by a <code>Line Feed</code> (LF) character (ASCII 10), optionally preceded by a <code>Carriage Return</code> (CR) character (ASCII 13). The CR and LF characters are not included in the returned line. In fact, all CR characters are ignored by the pattern.
+
+If no argument is specified, then it is assumed to be the pattern <code>'*l'</code>, that is, the line reading pattern.
+
+Timeout for the reading operation is controlled by the [[#lua_socket_read_timeout|lua_socket_read_timeout]] config directive and the [[#tcpsock:settimeout|settimeout]] method. And the latter takes priority. For example:
+
+<geshi lang="lua">
+    sock:settimeout(1000)  -- one second timeout
+    local line, err, partial = sock:receive()
+    if not line then
+        ngx.say("failed to read a line: ", err)
+        return
+    end
+    ngx.say("successfully read a line: ", line)
+</geshi>
+
+It is important here to call the [[#tcpsock:settimeout|settimeout]] method ''before'' calling this method.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:receiveuntil ==
+'''syntax:''' ''iterator = tcpsock:receiveuntil(pattern, options?)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+This method returns an iterator Lua function that can be called to read the data stream until it sees the specified pattern or an error occurs.
+
+Here is an example for using this method to read a data stream with the boundary sequence <code>--abcedhb</code>:
+
+<geshi lang="lua">
+    local reader = sock:receiveuntil("\r\n--abcedhb")
+    local data, err, partial = reader()
+    if not data then
+        ngx.say("failed to read the data stream: ", err)
+    end
+    ngx.say("read the data stream: ", data)
+</geshi>
+
+When called without any argument, the iterator function returns the received data right ''before'' the specified pattern string in the incoming data stream. So for the example above, if the incoming data stream is <code>'hello, world! -agentzh\r\n--abcedhb blah blah'</code>, then the string <code>'hello, world! -agentzh'</code> will be returned.
+
+In case of error, the iterator function will return <code>nil</code> along with a string describing the error and the partial data bytes that have been read so far.
+
+The iterator function can be called multiple times and can be mixed safely with other cosocket method calls or other iterator function calls.
+
+The iterator function behaves differently (i.e., like a real iterator) when it is called with a <code>size</code> argument. That is, it will read that <code>size</code> of data on each invocation and will return <code>nil</code> at the last invocation (either sees the boundary pattern or meets an error). For the last successful invocation of the iterator function, the <code>err</code> return value will be <code>nil</code> too. The iterator function will be reset after the last successful invocation that returns <code>nil</code> data and <code>nil</code> error. Consider the following example:
+
+<geshi lang="lua">
+    local reader = sock:receiveuntil("\r\n--abcedhb")
+
+    while true then
+        local data, err, partial = reader(4)
+        if not data then
+            if err then
+                ngx.say("failed to read the data stream: ", err)
+                break
+            end
+
+            ngx.say("read done")
+            break
+        end
+        ngx.say("read chunk: [", data, "]")
+    end
+</geshi>
+
+Then for the incoming data stream <code>'hello, world! -agentzh\r\n--abcedhb blah blah'</code>, we shall get the following output from the sample code above:
+
+<geshi lang="text">
+    read chunk: [hell]
+    read chunk: [o, w]
+    read chunk: [orld]
+    read chunk: [! -a]
+    read chunk: [gent]
+    read chunk: [zh]
+    read done
+</geshi>
+
+Note that, the actual data returned ''might'' be a little longer than the size limit specified by the <code>size</code> argument when the boundary pattern has ambiguity for streaming parsing. Near the boundary of the data stream, the data string actually returned could also be shorter than the size limit.
+
+Timeout for the iterator function's reading operation is controlled by the [[#lua_socket_read_timeout|lua_socket_read_timeout]] config directive and the [[#tcpsock:settimeout|settimeout]] method. And the latter takes priority. For example:
+
+<geshi lang="lua">
+    local readline = sock:receiveuntil("\r\n")
+
+    sock:settimeout(1000)  -- one second timeout
+    line, err, partial = readline()
+    if not line then
+        ngx.say("failed to read a line: ", err)
+        return
+    end
+    ngx.say("successfully read a line: ", line)
+</geshi>
+
+It is important here to call the [[#tcpsock:settimeout|settimeout]] method ''before'' calling the iterator function (note that the <code>receiveuntil</code> call is irrelevant here).
+
+As from the <code>v0.5.1</code> release, this method also takes an optional <code>options</code> table argument to control the behavior. The following options are supported:
+
+* <code>inclusive</code>
+
+The <code>inclusive</code> takes a boolean value to control whether to include the pattern string in the returned data string. Default to <code>false</code>. For example,
+
+<geshi lang="lua">
+    local reader = tcpsock:receiveuntil("_END_", { inclusive = true })
+    local data = reader()
+    ngx.say(data)
+</geshi>
+
+Then for the input data stream <code>"hello world _END_ blah blah blah"</code>, then the example above will output <code>hello world _END_</code>, including the pattern string <code>_END_</code> itself.
+
+This method was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:close ==
+'''syntax:''' ''ok, err = tcpsock:close()''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Closes the current TCP or stream unix domain socket. It returns the <code>1</code> in case of success and returns <code>nil</code> with a string describing the error otherwise.
+
+Note that there is no need to call this method on socket objects that have invoked the [[#tcpsock:setkeepalive|setkeepalive]] method because the socket object is already closed (and the current connection is saved into the built-in connection pool).
+
+Socket objects that have not invoked this method (and associated connections) will be closed when the socket object is released by the Lua GC (Garbage Collector) or the current client HTTP request finishes processing.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:settimeout ==
+'''syntax:''' ''tcpsock:settimeout(time)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Set the timeout value in milliseconds for subsequent socket operations ([[#tcpsock:connect|connect]], [[#tcpsock:receive|receive]], and iterators returned from [[#tcpsock:receiveuntil|receiveuntil]]).
+
+Settings done by this method takes priority over those config directives, i.e., [[#lua_socket_connect_timeout|lua_socket_connect_timeout]], [[#lua_socket_send_timeout|lua_socket_send_timeout]], and [[#lua_socket_read_timeout|lua_socket_read_timeout]].
+
+Note that this method does ''not'' affect the [[#lua_socket_keepalive_timeout|lua_socket_keepalive_timeout]] setting; the <code>timeout</code> argument to the [[#tcpsock:setkeepalive|setkeepalive]] method should be used for this purpose instead.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:setoption ==
+'''syntax:''' ''tcpsock:setoption(option, value?)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+This function is added for [http://w3.impa.br/~diego/software/luasocket/tcp.html LuaSocket] API compatibility and does nothing for now. Its functionality will be implemented in future.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:setkeepalive ==
+'''syntax:''' ''ok, err = tcpsock:setkeepalive(timeout?, size?)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Puts the current socket's connection immediately into the cosocket built-in connection pool and keep it alive until other [[#tcpsock:connect|connect]] method calls request it or the associated maximal idle timeout is expired.
+
+The first optional argument, <code>timeout</code>, can be used to specify the maximal idle timeout (in milliseconds) for the current connection. If omitted, the default setting in the [[#lua_socket_keepalive_timeout|lua_socket_keepalive_timeout]] config directive will be used. If the <code>0</code> value is given, then the timeout interval is unlimited.
+
+The second optional argument, <code>size</code>, can be used to specify the maximal number of connections allowed in the connection pool for the current server (i.e., the current host-port pair or the unix domain socket file path). Note that the size of the connection pool cannot be changed once the pool is created. When this argument is omitted, the default setting in the [[#lua_socket_pool_size|lua_socket_pool_size]] config directive will be used.
+
+When the connection pool exceeds the available size limit, the least recently used (idle) connection already in the pool will be closed to make room for the current connection.
+
+Note that the cosocket connection pool is per Nginx worker process rather than per Nginx server instance, so the size limit specified here also applies to every single Nginx worker process.
+
+Idle connections in the pool will be monitored for any exceptional events like connection abortion or unexpected incoming data on the line, in which cases the connection in question will be closed and removed from the pool.
+
+In case of success, this method returns <code>1</code>; otherwise, it returns <code>nil</code> and a string describing the error.
+
+This method also makes the current cosocket object enter the "closed" state, so there is no need to manually call the [[#tcpsock:close|close]] method on it afterwards.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== tcpsock:getreusedtimes ==
+'''syntax:''' ''count, err = tcpsock:getreusedtimes()''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+This method returns the (successfully) reused times for the current connection. In case of error, it returns <code>nil</code> and a string describing the error.
+
+If the current connection does not come from the built-in connection pool, then this method always returns <code>0</code>, that is, the connection has never been reused (yet). If the connection comes from the connection pool, then the return value is always non-zero. So this method can also be used to determine if the current connection comes from the pool.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.
+
+== ngx.socket.connect ==
+'''syntax:''' ''tcpsock, err = ngx.socket.connect(host, port)''
+
+'''syntax:''' ''tcpsock, err = ngx.socket.connect("unix:/path/to/unix-domain.socket")''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+This function is a shortcut for combining [[#ngx.socket.tcp|ngx.socket.tcp()]] and the [[#tcpsock:connect|connect()]] method call in a single operation. It is actually implemented like this:
+
+<geshi lang="lua">
+    local sock = ngx.socket.tcp()
+    local ok, err = sock:connect(...)
+    if not ok then
+        return nil, err
+    end
+    return sock
+</geshi>
+
+There is no way to use the [[#tcpsock:settimeout|settimeout]] method to specify connecting timeout for this method and the [[#lua_socket_connect_timeout|lua_socket_connect_timeout]] directive must be set at configure time instead.
+
+This feature was first introduced in the <code>v0.5.0rc1</code> release.

+'''syntax:''' ''co = ngx.thread.spawn(func, arg1, arg2, ...)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Spawns a new user "light thread" with the Lua function <code>func</code> as well as those optional arguments <code>arg1</code>, <code>arg2</code>, and etc. Returns a Lua thread (or Lua coroutine) object represents this "light thread".
+
+"Light threads" are just a special kind of Lua coroutines that are scheduled by the ngx_lua module.
+
+Before <code>ngx.thread.spawn</code> returns, the <code>func</code> will be called with those optional arguments until it returns, aborts with an error, or gets yielded due to I/O operations via the [[#Nginx API for Lua|Nginx API for Lua]] (like [[#tcpsock:receive|tcpsock:receive]]).
+
+After <code>ngx.thread.spawn</code> returns, the newly-created "light thread" will keep running asynchronously usually at various I/O events.
+
+All the Lua code chunks running by [[#rewrite_by_lua|rewrite_by_lua]], [[#access_by_lua|access_by_lua]], and [[#content_by_lua|content_by_lua]] are in a boilerplate "light thread" created automatically by ngx_lua. Such boilerplate "light thread" are also called "entry threads".
+
+By default, the corresponding Nginx handler (e.g., [[#rewrite_by_lua|rewrite_by_lua]] handler) will not terminate until
+# both the "entry thread" and all the user "light threads" terminates,
+# a "light thread" (either the "entry thread" or a user "light thread" aborts by calling [[#ngx.exit|ngx.exit]], [[#ngx.exec|ngx.exec]], [[#ngx.redirect|ngx.redirect]], or [[#ngx.req.set_uri|ngx.req.set_uri(uri, true)]], or
+# the "entry thread" terminates with a Lua error.
+
+When the user "light thread" terminates with a Lua error, however, it will not abort other running "light threads" like the "entry thread" does.
+
+Due to the limitation in the Nginx subrequest model, it is not allowed to abort a running Nginx subrequest in general. So it is also prohibited to abort a running "light thread" that is pending on one ore more Nginx subrequests. You must call [[#ngx.thread.wait|ngx.thread.wait]] to wait for those "light thread" to terminate before quitting the "world". A notable exception here is that you can abort pending subrequests by calling [[#ngx.exit|ngx.exit]] with and only with the status code <code>ngx.ERROR</code> (-1), <code>408</code>, <code>444</code>, or <code>499</code>.
+
+The "light threads" are not scheduled in a pre-emptive way. In other words, no time-slicing is performed automatically. A "light thread" will keep running exclusively on the CPU until
+# a (nonblocking) I/O operation cannot be completed in a single run,
+# it calls [[#coroutine.yield|coroutine.yield]] to actively give up execution, or
+# it is aborted by a Lua error or an invocation of [[#ngx.exit|ngx.exit]], [[#ngx.exec|ngx.exec]], [[#ngx.redirect|ngx.redirect]], or [[#ngx.req.set_uri|ngx.req.set_uri(uri, true)]].
+
+For the first two cases, the "light thread" will usually be resumed later by the ngx_lua scheduler unless a "stop-the-world" event happens.
+
+User "light threads" can create "light threads" themselves and normal user coroutiens created by [[#coroutine.create|coroutine.create]] can also create "light threads". The coroutine (be it a normal Lua coroutine or a "light thread") that directly spawns the "light thread" is called the "parent coroutine" for the "light thread" newly spawned.
+
+The "parent coroutine" can call [[#ngx.thread.wait|ngx.thread.wait]] to wait on the termination of its child "light thread".
+
+You can call coroutine.status() and coroutine.yield() on the "light thread" coroutines.
+
+The status of the "light thread" coroutine can be "zombie" if
+# the current "light thread" already terminates (either successfully or with an error),
+# its parent coroutine is still alive, and
+# its parent coroutine is not waiting on it with [[#ngx.thread.wait|ngx.thread.wait]].
+
+The following example demonstrates the use of coroutine.yield() in the "light thread" coroutines
+to do manual time-slicing:
+
+<geshi lang="lua">
+    local yield = coroutine.yield
+
+    function f()
+        local self = coroutine.running()
+        ngx.say("f 1")
+        yield(self)
+        ngx.say("f 2")
+        yield(self)
+        ngx.say("f 3")
+    end
+
+    local self = coroutine.running()
+    ngx.say("0")
+    yield(self)
+
+    ngx.say("1")
+    ngx.thread.spawn(f)
+
+    ngx.say("2")
+    yield(self)
+
+    ngx.say("3")
+    yield(self)
+
+    ngx.say("4")
+</geshi>
+
+Then it will generate the output
+
+<geshi lang="text">
+    0
+    1
+    f 1
+    2
+    f 2
+    3
+    f 3
+    4
+</geshi>
+
+"Light threads" are mostly useful for doing concurrent upstream requests in a single Nginx request handler, kinda like a generalized version of [[#ngx.location.capture_multi|ngx.location.capture_multi]] that can work with all the [[#Nginx API for Lua|Nginx API for Lua]]. The following example demonstrates parallel requests to MySQL, Memcached, and upstream HTTP services in a single Lua handler, and outputting the results in the order that they actually return (very much like the Facebook BigPipe model):
+
+<geshi lang="lua">
+    -- query mysql, memcached, and a remote http service at the same time,
+    -- output the results in the order that they
+    -- actually return the results.
+
+    local mysql = require "resty.mysql"
+    local memcached = require "resty.memcached"
+
+    local function query_mysql()
+        local db = mysql:new()
+        db:connect{
+                    host = "127.0.0.1",
+                    port = 3306,
+                    database = "test",
+                    user = "monty",
+                    password = "mypass"
+                  }
+        local res, err, errno, sqlstate =
+                db:query("select * from cats order by id asc")
+        db:set_keepalive(0, 100)
+        ngx.say("mysql done: ", cjson.encode(res))
+    end
+
+    local function query_memcached()
+        local memc = memcached:new()
+        memc:connect("127.0.0.1", 11211)
+        local res, err = memc:get("some_key")
+        ngx.say("memcached done: ", res)
+    end
+
+    local function query_http()
+        local res = ngx.location.capture("/my-http-proxy")
+        ngx.say("http done: ", res.body)
+    end
+
+    ngx.thread.spawn(query_mysql)      -- create thread 1
+    ngx.thread.spawn(query_memcached)  -- create thread 2
+    ngx.thread.spawn(query_http)       -- create thread 3 
+</geshi>
+
+This API was first enabled in the <code>v0.7.0</code> release.
+
+== ngx.thread.wait ==
+'''syntax:''' ''ok, res1, res2, ... = ngx.thread.wait(thread1, thread2, ...)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Waits on one or more child "light threads" and returns the results of the first "light thread" that terminates (either successfully or with an error).
+
+The arguments <code>thread1</code>, <code>thread2</code>, and etc are the Lua thread objects returned by earlier calls of [[#ngx.thread.spawn|ngx.thread.spawn]].
+
+The return values have exactly the same meaning as [[#coroutine.resume|coroutine.resume]], that is, the first value returned is a boolean value indicating whether the "light thread" terminates successfully or not, and subsequent values returned are the return values of the user Lua function that was used to spawn the "light thread" (in case of success) or the error object (in case of failure).
+
+Only the direct "parent coroutine" can wait on its child "light thread", otherwise a Lua exception will be raised.
+
+The following example demonstrates the use of <code>ngx.thread.wait</code> and [[#ngx.location.capture|ngx.location.capture]] to emulate [[#ngx.location.capture_multi|ngx.location.capture_multi]]:
+
+<geshi lang="lua">
+    local capture = ngx.location.capture
+    local spawn = ngx.thread.spawn
+    local wait = ngx.thread.wait
+    local say = ngx.say
+
+    local function fetch(uri)
+        return capture(uri)
+    end
+
+    local threads = {
+        spawn(fetch, "/foo"),
+        spawn(fetch, "/bar"),
+        spawn(fetch, "/baz")
+    }
+
+    for i = 1, #threads do
+        local ok, res = wait(threads[i])
+        if not ok then
+            say(i, ": failed to run: ", res)
+        else
+            say(i, ": status: ", res.status)
+            say(i, ": body: ", res.body)
+        end
+    end
+</geshi>
+
+Here it essentially implements the "wait all" model.
+
+And below is an example demonstrating the "wait any" model:
+
+<geshi lang="lua">
+    function f()
+        ngx.sleep(0.2)
+        ngx.say("f: hello")
+        return "f done"
+    end
+
+    function g()
+        ngx.sleep(0.1)
+        ngx.say("g: hello")
+        return "g done"
+    end
+
+    local tf, err = ngx.thread.spawn(f)
+    if not tf then
+        ngx.say("failed to spawn thread f: ", err)
+        return
+    end
+
+    ngx.say("f thread created: ", coroutine.status(tf))
+
+    local tg, err = ngx.thread.spawn(g)
+    if not tg then
+        ngx.say("failed to spawn thread g: ", err)
+        return
+    end
+
+    ngx.say("g thread created: ", coroutine.status(tg))
+
+    ok, res = ngx.thread.wait(tf, tg)
+    if not ok then
+        ngx.say("failed to wait: ", res)
+        return
+    end
+
+    ngx.say("res: ", res)
+
+    -- stop the "world", aborting other running threads
+    ngx.exit(ngx.OK)
+</geshi>
+
+And it will generate the following output:
+
+<geshi lang="text">
+    f thread created: running
+    g thread created: running
+    g: hello
+    res: g done
+</geshi>
+
+This API was first enabled in the <code>v0.7.0</code> release.
+
+== ngx.on_abort ==
+'''syntax:''' ''ok, err = ngx.on_abort(callback)''
+
+'''context:''' ''rewrite_by_lua*, access_by_lua*, content_by_lua*''
+
+Registers a user Lua function as the callback which gets called automatically when the client closes the (downstream) connection prematurely.
+
+Returns <code>1</code> if the callback is registered successfully or returns <code>nil</code> and a string describing the error otherwise.
+
+All the [[#Nginx API for Lua|Nginx API for Lua]] can be used in the callback function because the function is run in a special "light thread", just as those "light threads" created by [[#ngx.thread.spawn|ngx.thread.spawn]].
+
+The callback function can decide what to do with the client abortion event all by itself. For example, it can simply ignore the event by doing nothing and the current Lua request handler will continue executing without interruptions. And the callback function can also decide to terminate everything by calling [[#ngx.exit|ngx.exit]], for example,
+
+<geshi lang="lua">
+    local function my_cleanup()
+        -- custom cleanup work goes here, like cancelling a pending DB transaction
+
+        -- now abort all the "light threads" running in the current request handler
+        ngx.exit(499)
+    end
+
+    local ok, err = ngx.on_abort(my_cleanup)
+    if not ok then
+        ngx.log(ngx.ERR, "failed to register the on_abort callback: ", err)
+        ngx.exit(500)
+    end
+</geshi>
+
+When [[#lua_check_client_abort|lua_check_client_abort]] is set to <code>off</code> (which is the default), then this function call will always return the error message "lua_check_client_abort is off".
+
+According to the current implementation, this function can only be called once in a single request handler; subsequent calls will return the error message "duplicate call".
+
+This API was first introduced in the <code>v0.7.4</code> release.
+
+See also [[#lua_check_client_abort|lua_check_client_abort]].

+'''context:''' ''set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*''
+
+This mechanism allows calling other nginx C modules' directives that are implemented by [https://github.com/simpl/ngx_devel_kit Nginx Devel Kit] (NDK)'s set_var submodule's <code>ndk_set_var_value</code>.
+
+For example, the following [[HttpSetMiscModule]] directives can be invoked this way:
+
+* [[HttpSetMiscModule#set_quote_sql_str|set_quote_sql_str]]
+* [[HttpSetMiscModule#set_quote_pgsql_str|set_quote_pgsql_str]]
+* [[HttpSetMiscModule#set_quote_json_str|set_quote_json_str]]

+* [[HttpSetMiscModule#set_encode_base64|set_sha1]]
+* [[HttpSetMiscModule#set_decode_base64|set_md5]]
+
+For instance,
+
+<geshi lang="lua">
+    local res = ndk.set_var.set_escape_uri('a/b');
+    -- now res == 'a%2fb'
+</geshi>
+
+Similarly, the following directives provided by [[HttpEncryptedSessionModule]] can be invoked from within Lua too:
+
+* [[HttpEncryptedSessionModule#set_encrypt_session|set_encrypt_session]]
+* [[HttpEncryptedSessionModule#set_decrypt_session|set_decrypt_session]]
+
+This feature requires the [https://github.com/simpl/ngx_devel_kit ngx_devel_kit] module.

+= Lua/LuaJIT bytecode support =
+
+As from the <code>v0.5.0rc32</code> release, all <code>*_by_lua_file</code> configure directives (such as [[#content_by_lua_file|content_by_lua_file]]) support loading Lua 5.1 and LuaJIT 2.0 raw bytecode files directly.
+
+Please note that the bytecode format used by LuaJIT 2.0 is not compatible with that used by the standard Lua 5.1 interpreter. So if using LuaJIT 2.0 with ngx_lua, LuaJIT compatible bytecode files must be generated as shown:
+
+<geshi lang="bash">
+    /path/to/luajit/bin/luajit -b /path/to/input_file.lua /path/to/output_file.luac
+</geshi>
+
+The <code>-bg</code> option can be used to include debug information in the LuaJIT bytecode file:
+
+<geshi lang="bash">
+    /path/to/luajit/bin/luajit -bg /path/to/input_file.lua /path/to/output_file.luac
+</geshi>
+
+Please refer to the official LuaJIT documentation on the <code>-b</code> option for more details:
+
+http://luajit.org/running.html#opt_b
+
+Similarly, if using the standard Lua 5.1 interpreter with ngx_lua, Lua compatible bytecode files must be generated using the <code>luac</code> commandline utility as shown:
+
+<geshi lang="bash">
+    luac -o /path/to/output_file.luac /path/to/input_file.lua
+</geshi>
+
+Unlike as with LuaJIT, debug information is included in standard Lua 5.1 bytecode files by default. This can be striped out by specifying the <code>-s</code> option as shown:
+
+<geshi lang="bash">
+    luac -s -o /path/to/output_file.luac /path/to/input_file.lua
+</geshi>
+
+Attempts to load standard Lua 5.1 bytecode files into ngx_lua instances linked to LuaJIT 2.0 or vice versa, will result in an error message, such as that below, being logged into the Nginx <code>error.log</code> file:
+
+<geshi lang="text">
+    [error] 13909#0: *1 failed to load Lua inlined code: bad byte-code header in /path/to/test_file.luac
+</geshi>
+
+Loading bytecode files via the Lua primitives like <code>require</code> and <code>dofile</code> should always work as expected.
+
+= HTTP 1.0 support =
+
+The HTTP 1.0 protocol does not support chunked output and requires an explicit <code>Content-Length</code> header when the response body is not empty in order to support the HTTP 1.0 keep-alive.
+So when a HTTP 1.0 request is made and the [[#lua_http10_buffering|lua_http10_buffering]] directive is turned <code>on</code>, ngx_lua will buffer the
+output of [[#ngx.say|ngx.say]] and [[#ngx.print|ngx.print]] calls and also postpone sending response headers until all the response body output is received.
+At that time ngx_lua can calculate the total length of the body and construct a proper <code>Content-Length</code> header to return to the HTTP 1.0 client.
+If the <code>Content-Length</code> response header is set in the running Lua code, however, this buffering will be disabled even if the [[#lua_http10_buffering|lua_http10_buffering]] directive is turned <code>on</code>.
+
+For large streaming output responses, it is important to disable the [[#lua_http10_buffering|lua_http10_buffering]] directive to minimise memory usage.
+
+Note that common HTTP benchmark tools such as <code>ab</code> and <code>http_load</code> issue HTTP 1.0 requests by default.
+To force <code>curl</code> to send HTTP 1.0 requests, use the <code>-0</code> option.
+
+= Data Sharing within an Nginx Worker =
+
+To globally share data among all the requests handled by the same nginx worker process, encapsulate the shared data into a Lua module, use the Lua <code>require</code> builtin to import the module, and then manipulate the shared data in Lua. This works because required Lua modules are loaded only once and all coroutines will share the same copy of the module. Note however that Lua global variables WILL NOT persist between requests because of the one-coroutine-per-request isolation design.
+
+Here is a complete small example:
+
+<geshi lang="lua">
+    -- mydata.lua
+    module(...)
+ 
+    local data = {
+        dog = 3,
+        cat = 4,
+        pig = 5,
+    }
+ 
+    function get_age(name)
+        return data[name]
+    end
+</geshi>
+
+and then accessing it from <code>nginx.conf</code>:
+
+<geshi lang="nginx">
+    location /lua {
+        content_by_lua '
+            local mydata = require "mydata"
+            ngx.say(mydata.get_age("dog"))
+        ';
+    }
+</geshi>
+
+The <code>mydata</code> module in this example will only be loaded and run on the first request to the location <code>/lua</code>,
+and all subsequent requests to the same nginx worker process will use the reloaded instance of the
+module as well as the same copy of the data in it, until a <code>HUP</code> signal is sent to the Nginx master process to force a reload.
+This data sharing technique is essential for high performance Lua applications based on this module.
+
+Note that this data sharing is on a ''per-worker'' basis and not on a ''per-server'' basis. That is, when there are multiple nginx worker processes under an Nginx master, data sharing cannot cross the process boundary between these workers.
+
+If server-wide data sharing is required, then use one or more of the following approaches:
+# Use the [[#ngx.shared.DICT|ngx.shared.DICT]] API provided by this module.
+# Use only a single nginx worker and a single server (this is however not recommended when there is a multi core CPU or multiple CPUs in a single machine).
+# Use data storage mechanisms such as <code>memcached</code>, <code>redis</code>, <code>MySQL</code> or <code>PostgreSQL</code>. [http://openresty.org The ngx_openresty bundle] associated with this module comes with a set of companion Nginx modules and Lua libraries that provide interfaces with these data storage mechanisms.
+
+= Known Issues =
+
+== TCP socket connect operation issues ==
+The [[#tcpsock:connect|tcpsock:connect]] method may indicate <code>success</code> despite connection failures such as with <code>Connection Refused</code> errors. 
+
+However, later attempts to manipulate the cosocket object will fail and return the actual error status message generated by the failed connect operation. 
+
+This issue is due to limitations in the Nginx event model and only appears to affect Mac OS X.
+
+== Lua Coroutine Yielding/Resuming ==
+* As the module's predefined Nginx I/O API uses the coroutine yielding/resuming mechanism, user code should not call any Lua modules that use the Lua coroutine mechanism in order to prevent conflicts with the module's predefined Nginx API methods such as [[#ngx.location.capture|ngx.location.capture]] (Actually, coroutine modules have been masked off in [[#content_by_lua|content_by_lua]] directives and others). This limitation is significant and work is ongoing on an alternative coroutine implementation that can fit into the Nginx event model to address this. When this is done, it will be possible to use the Lua coroutine mechanism freely as it is in standard Lua implementations.
+* Lua's <code>dofile</code> builtin is implemented as a C function in both Lua 5.1 and LuaJIT 2.0 and when [[#ngx.location.capture|ngx.location.capture]] is called, [[#ngx.exec|ngx.exec]], [[#ngx.exit|ngx.exit]] or [[#ngx.req.read_body|ngx.req.read_body]] or similar in the file to be loaded by <code>dofile</code>, a coroutine yield across the C function boundary will be initiated. This however is not normally allowed within ngx_lua and will usually result in error messages like <code>lua handler aborted: runtime error: attempt to yield across C-call boundary</code>. To avoid this, define a real Lua module and use the Lua <code>require</code> builtin instead.
+* As the standard Lua 5.1 interpreter's VM is not fully resumable, the methods [[#ngx.location.capture|ngx.location.capture]], [[#ngx.location.capture_multi|ngx.location.capture_multi]], [[#ngx.redirect|ngx.redirect]], [[#ngx.exec|ngx.exec]], and [[#ngx.exit|ngx.exit]] cannot be used within the context of a Lua [http://www.lua.org/manual/5.1/manual.html#pdf-pcall pcall()] or [http://www.lua.org/manual/5.1/manual.html#pdf-xpcall xpcall()] when the standard Lua 5.1 interpreter is used and the <code>attempt to yield across metamethod/C-call boundary</code> error will be produced. Please use LuaJIT 2.0, which supports a fully resumable VM, to avoid this.
+
+== Lua Variable Scope ==
+Care should be taken when importing modules and this form should be used:
+
+<geshi lang="lua">
+    local xxx = require('xxx')
+</geshi>
+
+: instead of the old deprecated form:
+
+<geshi lang="lua">
+    require('xxx')
+</geshi>
+
+: If the old form is required, force reload the module for every request by using the <code>package.loaded.<module></code> command:
+
+<geshi lang="lua">
+    package.loaded.xxx = nil
+    require('xxx')
+</geshi>
+
+It is recommended to always place the following piece of code at the end of Lua modules that use the I/O operations to prevent casual use of module-level global variables that are shared among ''all'' requests:
+
+<geshi lang="lua">
+    local class_mt = {
+        -- to prevent use of casual module global variables
+        __newindex = function (table, key, val)
+            error('attempt to write to undeclared variable "' .. key .. '"')
+        end
+    }
+    setmetatable(_M, class_mt)
+</geshi>
+
+This will guarantee that local variables in the Lua module functions are all declared with the <code>local</code> keyword, otherwise a runtime exception will be thrown. It prevents undesirable race conditions while accessing such variables. See [[#Data_Sharing_within_an_Nginx_Worker|Data Sharing within an Nginx Worker]] for the reasons behind this.
+
+== Locations Configured by Subrequest Directives of Other Modules ==
+The [[#ngx.location.capture|ngx.location.capture]] and [[#ngx.location.capture_multi|ngx.location.capture_multi]] directives cannot capture locations that include the [[HttpEchoModule#echo_location|echo_location]], [[HttpEchoModule#echo_location_async|echo_location_async]], [[HttpEchoModule#echo_subrequest|echo_subrequest]], or [[HttpEchoModule#echo_subrequest_async|echo_subrequest_async]] directives.
+
+<geshi lang="nginx">
+    location /foo {
+        content_by_lua '
+            res = ngx.location.capture("/bar")
+        ';
+    }
+    location /bar {
+        echo_location /blah;
+    }
+    location /blah {
+        echo "Success!";
+    }
+</geshi>
+
+<geshi lang="nginx">
+    $ curl -i http://example.com/foo
+</geshi>
+
+will not work as expected.
+
+== Special PCRE Sequences ==
+PCRE sequences such as <code>\d</code>, <code>\s</code>, or <code>\w</code>, require special attention because in string literals, the backslash character, <code>\</code>, is stripped out by both the Lua language parser and by the Nginx config file parser before processing. So the following snippet will not work as expected:
+
+<geshi lang="nginx">
+    # nginx.conf
+    ? location /test {
+    ?     content_by_lua '
+    ?         local regex = "\d+"  -- THIS IS WRONG!!
+    ?         local m = ngx.re.match("hello, 1234", regex)
+    ?         if m then ngx.say(m[0]) else ngx.say("not matched!") end
+    ?     ';
+    ? }
+    # evaluates to "not matched!"
+</geshi>
+
+To avoid this, ''double'' escape the backslash:
+
+<geshi lang="nginx">
+    # nginx.conf
+    location /test {
+        content_by_lua '
+            local regex = "\\\\d+"
+            local m = ngx.re.match("hello, 1234", regex)
+            if m then ngx.say(m[0]) else ngx.say("not matched!") end
+        ';
+    }
+    # evaluates to "1234"
+</geshi>
+
+Here, <code>\\\\d+</code> is stripped down to <code>\\d+</code> by the Nginx config file parser and this is further stripped down to <code>\d+</code> by the Lua language parser before running.
+
+Alternatively, the regex pattern can be presented as a long-bracketed Lua string literal by encasing it in "long brackets", <code>&#91;[...]]</code>, in which case backslashes have to only be escaped once for the Nginx config file parser. 
+
+<geshi lang="nginx">
+    # nginx.conf
+    location /test {
+        content_by_lua '
+            local regex = [[\\d+]]
+            local m = ngx.re.match("hello, 1234", regex)
+            if m then ngx.say(m[0]) else ngx.say("not matched!") end
+        ';
+    }
+    # evaluates to "1234"
+</geshi>
+
+Here, <code>&#91;[\\d+]]</code> is stripped down to <code>&#91;[\d+]]</code> by the Nginx config file parser and this is processed correctly.
+
+Note that a longer from of the long bracket, <code>[=[...]=]</code>, may be required if the regex pattern contains <code>&#91;...]</code> sequences. 
+The <code>[=[...]=]</code> form may be used as the default form if desired.
+
+<geshi lang="nginx">
     # nginx.conf
     location /test {
         content_by_lua '
-            local regex = [=[ [0-9]+ ]=]

 The possibilities are unlimited as the module allows bringing together various elements within Nginx as well as exposing the power of the Lua language to the user.

This is particularly the case when LuaJIT 2.0 is enabled.

-* bugfix: fixed a bug when the both the main request and the subrequest are POST requests with a body: we should not forward the main request's <code>Content-Length</code> headers to the user subrequests. thanks 朱峰.
-* feature: implemented the API for reading response headers from within Lua: <code>value = ngx.header.HEADER</code>, see [[#ngx.header.HEADER|ngx.header.HEADER]].
-* bugfix: fixed a bug when setting a multi-value response header to a single value (via writing to [[#ngx.header.HEADER|ngx.header.HEADER]]): the single value will be repeated on each old value.
-* bugfix: fixed an issue in [[#ngx.redirect|ngx.redirect]], [[#ngx.exit|ngx.exit]], and [[#ngx.exec|ngx.exec]]: these function calls would be intercepted by Lua <code>pcall</code>/<code>xpcall</code> because they used Lua exceptions; now they use Lua yield just as [[#ngx.location.capture|ngx.location.capture]]. thanks @hugozhu for reporting this.
-* feature: now we also return the <code>Last-Modified</code> header (if any) for the subrequest response object. thanks @cyberty and sexybabes.
-* feature: now [[#ngx.exec|ngx.exec]] supports Lua table as the second args argument value. thanks sexybabes.
-* feature: implemented the [[#ngx.headers_sent|ngx.headers_sent]] API to check if response headers are sent (by ngx_lua). thanks @hugozhu.
-* feature: exposes the CRC-32 API of the Nginx core to the Lua land, in the form of the [[#ngx.crc32_short|ngx.crc32_short]] and [[#ngx.crc32_long|ngx.crc32_long]] methods. thanks @Lance.
-* feature: now for HTTP 1.0 requests, we disable the automatic full buffering mode if the user sets the <code>Content-Length</code> response header before sending out the headers. this allows streaming output for HTTP 1.0 requests if the content length can be calculated beforehand. thanks 李子义.
-* bugfix: now we properly support setting the <code>Cache-Control</code> response header via the [[#ngx.header.HEADER|ngx.header.HEADER]] interface.
-* bugfix: no longer set header hash to <code>1</code>. use the <code>ngx_hash_key_lc</code> instead.
-* bugfix: calling [[#ngx.exec|ngx.exec]] to jump to a named location did not clear the context object of LuaNginxModule properly and might cause evil problems. thanks Nginx User.
-* bugfix: now we explicitly clear all the modules' contexts before dump to named location with [[#ngx.exec|ngx.exec]].
-* feature: implemented [[#ngx.req.set_uri|ngx.req.set_uri]] and [[#ngx.req.set_uri_args|ngx.req.set_uri_args]] to emulate [[HttpRewriteModule]]'s [[HttpRewriteModule#rewrite|rewrite]] directive. thanks Vladimir Protasov (utros) and Nginx User.
-* bugfix: now we skip rewrite phase Lua handlers altogether if [[HttpRewriteModule]]'s [[HttpRewriteModule#rewrite|rewrite]] directive issue a location re-lookup by changing URIs (but not including <code>rewrite ... break</code>). thanks Nginx User.
-* feature: added constant <code>ngx.HTTP_METHOD_NOT_IMPLEMENTED (501)</code>. thanks Nginx User.
-* feature: added new Lua functions [[#ngx.req.read_body|ngx.req.read_body]], [[#ngx.req.discard_body|ngx.req.discard_body]], [[#ngx.req.get_body_data|ngx.req.get_body_data]], and [[#ngx.req.get_body_file|ngx.req.get_body_file]]. thanks Tzury Bar Yochay for funding the development work.
-* bugfix: fixed hanging issues when using [[#ngx.exec|ngx.exec]] within [[#rewrite_by_lua|rewrite_by_lua]] and [[#access_by_lua|access_by_lua]]. thanks Nginx User for reporting it.
-* feature: added new Lua API [[#ngx.req.set_body_file|ngx.req.set_body_file]]. thanks Tzury Bar Yochay for funding the development work.
-* feature: added new Lua API [[#ngx.req.set_body_data|ngx.req.set_body_data]]. thanks Tzury Bar Yochay for funding the development work.
-* bugfix: [[#lua_need_request_body|lua_need_request_body]] should not skip requests with methods other than <code>POST</code> and <code>PUT</code>. thanks Nginx User.
-* bugfix: no longer free request body buffers that are not allocated by ourselves.
-* bugfix: now we allow setting [[#ngx.var.VARIABLE|ngx.var.VARIABLE]] to nil.
-* feature: added new directive [[#lua_shared_dict|lua_shared_dict]].
-* feature: added Lua API for the shm-based dictionary, see [[#ngx.shared.DICT|ngx.shared.DICT]].
-* bugfix: fixed spots of -Werror=unused-but-set-variable warning issued by gcc 4.6.0.
-* bugfix: [[#ndk.set_var.DIRECTIVE|ndk.set_var.DIRECTIVE]] had a memory issue and might pass empty argument values to the directive being called. thanks dannynoonan.
-* feature: added the <code>ctx</code> option to [[#ngx.location.capture|ngx.location.capture]]: you can now specify a custom Lua table to pass to the subrequest as its [[#ngx.ctx|ngx.ctx]]. thanks @hugozhu.
-* feature: added the [[#ngx.encode_args|ngx.encode_args]] method to encode a Lua code to a URI query string. thanks 郭颖 (0597虾).
-* feature: [[#ngx.location.capture|ngx.location.capture]] and [[#ngx.exec|ngx.exec]] now supports the same Lua args table format as in ngx.encode_args. thanks 郭颖 (0597虾).
-* bugfix: <code>Cache-Control</code> header modification might introduce empty value headers when using with the standard HttpHeadersModule.
-* feature: added [[#ngx.hmac_sha1|ngx.hmac_sha1]]. thanks drdrxp.
-* docs: documented the long-existent [[#ngx.md5|ngx.md5]] and [[#ngx.md5_bin|ngx.md5_bin]] APIs.
-* docs: massive documentation improvements. thanks Nginx User.
-* feature: added new regex options <code>j</code> and <code>d</code> to [[#ngx.re.match|ngx.re.match]], [[#ngx.re.gmatch|ngx.re.gmatch]], [[#ngx.re.sub|ngx.re.sub]], and [[#ngx.re.gsub|ngx.re.gsub]] so as to enable the PCRE JIT mode and DFA mode, respectively. thanks @姜大炮 for providing the patch.
-* feature: added options <code>copy_all_vars</code> and <code>vars</code> to [[#ngx.location.capture|ngx.location.capture]] and [[#ngx.location.capture_multi|ngx.location.capture_multi]]. thanks Marcus Clyne for the patch.
-* feature: added new Lua API [[#ngx.now|ngx.now]] to return the current time (including the milliseconds part as the decimal part). thanks 林青.
-* feature: added new Lua API [[#ngx.update_time|ngx.update_time]] to forcibly updating Nginx's time cache.
-* feature: added <code>wait</code> boolean argument to [[#ngx.flush|ngx.flush]] to support synchronous flushing: <code>ngx.flush(true)</code> will not return until all the data has been flushed into the system send buffer or the send timeout has expired.
-* bugfix: now we check timed out downstream connections in our write event handler.
-* feature: added constant <code>ngx.HTTP_GATEWAY_TIMEOUT (504)</code> per Fry-kun in [https://github.com/chaoslawful/lua-nginx-module/issues/73 github issue #73].
-* bugfix: [[#ngx.var.VARIABLE|ngx.var.VARIABLE]] did not evaluate to <code>nil</code> when the Nginx variable's <code>valid</code> flag is <code>0</code>.
-* bugfix: there were various places where we did not check the pointer returned by the memory allocator.
-* bugfix: [[#ngx.req.set_header|ngx.req.set_header]] and [[#ngx.req.clear_header|ngx.req.clear_header]] did not handle the <code>Accept-Encoding</code> request headers properly. thanks 天街夜色.
-* bugfix: [[#ngx.req.set_header|ngx.req.set_header]] might cause invalid memory reads because Nginx request header values must be <code>NULL</code> terminated. thanks Maxim Dounin.
-* bugfix: removing builtin headers via [[#ngx.req.clear_header|ngx.req.clear_header]] and its equivalent in huge request headers with 20+ entries could result in data loss. thanks Chris Dumoulin.
-* bugfix: [[#ngx.req.get_uri_args|ngx.req.get_uri_args]] and [[#ngx.req.get_post_args|ngx.req.get_post_args]] now only parse up to <code>100</code> arguments by default. but one can specify the optional argument to these two methods to specify a custom maximum number of args. thanks Tzury Bar Yochay for reporting this.
-* bugfix: [[#ngx.req.get_headers|ngx.req.get_headers]] now only parse up to <code>100</code> request headers by default. but one can specify the optional argument to this method to specify a custom maximum number of headers.

-September 02, 2011

-'''New features'''
-
-* added the [[#header_filter_by_lua|header_filter_by_lua]] and [[#header_filter_by_lua_file|header_filter_by_lua_file]] directives. thanks Liseen Wan (万珣新).
-* implemented the PCRE regex API for Lua: [[#ngx.re.match|ngx.re.match]], [[#ngx.re.gmatch|ngx.re.gmatch]], [[#ngx.re.sub|ngx.re.sub]], and [[#ngx.re.gsub|ngx.re.gsub]].
-* now we add the <code>ngx</code> and <code>ndk</code> table into <code>package.loaded</code> such that the user can write <code>local ngx = require 'ngx'</code> and <code>local ndk = require 'ndk'</code>. thanks @Lance.
-* added new directive [[#lua_regex_cache_max_entries|lua_regex_cache_max_entries]] to control the upper limit of the worker-process-level compiled-regex cache enabled by the <code>o</code> regex option.
-* implemented the special [[#ngx.ctx|ngx.ctx]] Lua table for user programmers to store per-request Lua context data for their applications. thanks 欧远宁 for suggesting this feature.
-* now [[#ngx.print|ngx.print]] and [[#ngx.say|ngx.say]] allow (nested) array-like table arguments. the array elements in them will be sent piece by piece. this will avoid string concatenation for templating engines like [http://www.savarese.com/software/ltp/ ltp].
-* implemented the [[#ngx.req.get_post_args|ngx.req.get_post_args]] method for fetching url-encoded POST query arguments from within Lua.
-* implemented the [[#ngx.req.get_uri_args|ngx.req.get_uri_args]] method to fetch parsed URL query arguments from within Lua. thanks Bertrand Mansion (golgote).
-* added new function [[#ngx.parse_http_time|ngx.parse_http_time]], thanks James Hurst.
-* now we allow Lua boolean and <code>nil</code> values in arguments to [[#ngx.say|ngx.say]], [[#ngx.print|ngx.print]], [[#ngx.log|ngx.log]] and [[#print|print]].
-* added support for user C macros <code>LUA_DEFAULT_PATH</code> and <code>LUA_DEFAULT_CPATH</code>. for now we can only define them in <code>ngx_lua</code>'s <code>config</code> file because nginx <code>configure</code>'s <code>--with-cc-opt</code> option hates values with double-quotes in them. sigh. This feature is used by [http://openresty.org The ngx_openresty bundle] to bundle third party Lua libraries.
-
-'''Bug fixes'''
-
-* worked-around the "stack overflow" issue while using <code>luarocks.loader</code> and disabling [[#lua_code_cache|lua_code_cache]], as described as github issue #27. thanks Patrick Crosby.
-* fixed the <code>zero size buf in output</code> alert while combining [[#lua_need_request_body|lua_need_request_body]] on + [[#access_by_lua|access_by_lua]]/[[#rewrite_by_lua|rewrite_by_lua]] + [[HttpProxyModule#proxy_pass|proxy_pass]]/[[HttpFcgiModule#fastcgi_pass|fastcgi_pass]]. thanks Liseen Wan (万珣新).
-* fixed issues with HTTP 1.0 HEAD requests.
-* made setting <code>ngx.header.HEADER</code> after sending out response headers throw out a Lua exception to help debugging issues like github issue #49. thanks Bill Donahue (ikhoyo).
-* fixed an issue regarding defining global variables in C header files: we should have defined the global <code>ngx_http_lua_exception</code> in a single compilation unit. thanks @姜大炮.

+-- memcache:set(key, value[, expiry])
+--    Unconditionally sets a key to a given value in the memcache. The value for 'expiry' is the expiration
+--    time (default is 0, never expire).
+--     
+-- memcache:add(key, value[, expiry])
+--    Like set, but only stores in memcache if the key doesn't already exist.
+--    
+-- memcache:replace(key, value[, expiry])
+--    Like set, but only stores in memcache if the key already exists. The opposite of add.
+--    
+-- value = memcache:get(key)
+--    Retrieves a key from the memcache. Returns the value or nil
+--    
+-- values = memcache:get_multi(...)
+--    Retrieves multiple keys from the memcache doing just one query.  Returns a table of key/value pairs that were available.
+--    
+-- memcache:delete(key)
+--    Deletes a key. Returns true on deletion, false if the key was not found.
+--    
+-- value = memcache:incr(key[, value])
+--    Sends a command to the server to atomically increment the value for key by value, or by 1 if value is nil. 
+--    Returns nil if key doesn't exist on server, otherwise it returns the new value after incrementing. Value should be zero or greater.
+--    
+-- value = memcache:decr(key[, value])
+--    Like incr, but decrements. Unlike incr, underflow is checked and new values are capped at 0. If server value is 1, a decrement of 2 returns 0, not -1.
+--
+-- servers = memcache:stats([key])
+--    Returns a table of statistical data regarding the memcache server(s). Allowed keys are:
+--	'', 'malloc', 'sizes', 'slabs', 'items'
+--
+--  success = memcache:flush_all()
+--     Runs the memcached "flush_all" command on all configured hosts, emptying all their caches. 
+--
+--  memcache:disconnect_all()
+--     Closes all cached sockets to all memcached servers.
+--
+--  memcache:set_hash(hashfunc)
+--     Sets a custom hash function for key values. The default is a CRC32 hashing function.
+--     'hashfunc' should be defined receiving a single string parameter and returing a single integer value.
+--
+--  memcache:set_encode(func)
+--     Sets a custom encode function for serialising table values. 'func' should be defined receiving a single
+--     table value and returning a single string value.
+--
+--  memcache:set_decode(func)
+--     Sets a custom decode function for deserialising table values. 'func' should be defined receiving a 
+--     single single and returning a single table value
+--
+--  memcache:enable_compression(onflag)
+--     Turns data compression support on or off.
+--
+--  memcache:set_compress_threshold(size)
+--     Set the compression threshold. If the value to be stored is larger than `size' bytes (and compression 
+--     is enabled), compress before storing.
+--
+--  memcache:set_compress(func)
+--     Sets a custom data compression function. 'func' should be defined receiving a single string value and
+--     returning a single string value.
+--
+--  memcache:set_decompress(func)
+--     Sets a custom data decompression function. 'func' should be defined receiving a single string value and
+--     returning a single string value.
