Wed Jun 20 20:22:11 CEST 2012 Yaws 1.93
Security release
Use crypto:rand_bytes() instead of the cryptographically weak random module. Swedish security consultant and cryptographer Kalle Zetterlund discovered a way to - given a sequence of cookies produced by yaws_session_server - predict the next session id. Thus providing a gaping security hole into yaws servers that use the yaws_session_server to maintain cookie based HTTP sessions (klacke/kallez)
A denial of service bug has been corrected. Multippart POST processing on the yaws server side contained a list_to_atom/1 call which potentially makes it possible for an attacker to craft a continous list of POSTs, each potentially generating a new atom. This is a backwards incompatible fix since the upload code on the server side is user code. That code now needs to look for strings instead of atoms. For example the upload.yaws code in the www examples is changed. It searches now for the field "filename" instead of 'filename' (klacke)
make sure to always send proper strings to file:write() while logging (Nicolas Adiba)

Sat Sep 25 13:39:29 CEST 2010 Yaws 1.89
Maintenance release with a long series of fixes mostly from Steve Vinoski should not not include .yaws files, nor directories "protected" with an index file, nor directories protected by an auth directive. (Hans-Christian Esperer )
adjust to R14B change in gen_tcp:recv for {packet,http} mode Where we handle the return value of gen_tcp:recv while reading headers from the socket (such as with calls to yaws:do_recv), handle new R14B return values as well as existing return values for previous releases. (Steve)
for portability, use erlang:md5 rather than crypto md5 Since OpenSSL availability on Windows for working with the crypto module is apparently questionable, use the erlang:md5 function in place of the crypto md5 functions. (Steve)

Thu Mar 18 21:51:32 CET 2010 Yaws 1.88
Highlights in this release are, new SSL implementation is now default, FCGI enhhancements and IPV6 support.
ssl support for websockets, patch by wde
Erroneous common log format entries, time should be surrounded by brackets (Klacke)
When executing yaws --hup the order of the hosts in a virthost group wans't maintained, thus breaking the feature of pick first virthost on nomatch (Klacke)
set nodelay on FCGI TCP connection, and avoid 0-length FCGI gen_tcp:recv (steve)
Set {nodelay,true} on the TCP connection to the FCGI server to improve performance of small requests. (steve)
The code receives packets from the FCGI server and for some cases was extracting length fields from some packets and then making further gen_tcp:recv calls based on those length values. The code was not checking for length values of 0 before calling recv, and passing 0 to recv means to return all available bytes. For both correctness and performance, the code must avoid the recv calls altogether when the length is 0. (steve)
convert error atoms into error strings for fcgi_worker_fail (steve)
IpV6 support
The default value for partial_post_size was nolimit, not a good default value and also erroneoulsy documented (Klacke)
An atempt at having utf8 characters in the host names for yaws servers. Probably not entirely correct, but it works. (Klacke)
Anders Dahlin found that yaws log code doesn't delete the gen_event handler it adds error logger when terminating, that means that restarting yaws leaves old processes hanging around
dialyzer work (Klacke)
Closed Issue #31, made parsing of yaws.conf more tight complaining on e.g allowd_scripts = [ yaws ]
fix for FastCGI/PHP Issue ( (davide)
auth through .yaws_auth files has become broken, (Klacke)
allow caller to set Host header for SOAP requests (Steve)
added support for OTP new ssl implementation ,Also set it as default. It's possible through yaws.conf to use the old SSL. The new seems to work well though, I've tested with a wide set of browsers, and in general it seems to work (klacke)
Mon Jan 11 22:09:00 CET 2010 1.87
websocket support (davide and wde)
conditional compile of websockets, only use if the chosen erl supports it (klacke/steve)
patch by Andrei Soroker to strip the port part in #redir_self records - this patch may break some code, users that use redir_self() and unconditionally strip off their optional port number are affected
support some extra status codes in code_to_phrase (steve)
drop spaces before parsing ints - patch by Colm Dougan
proper handling of "/" appmod with excluded paths (patch from wde)
Added new unit tests for appmods, with both / and non-/ tests. The / tests include exclude_paths testing. (steve)
patch from wde solving a problem with appmod exclude paths and verify_upgrade
yaws_server: fixed the test for whether to close the socket. The yaws:outh_get_doclose() doesn't return a boolean and it requires the outh dicionary entry to be set (sometimes it isn't). (davide)
do not pass the --id option if the default id is used (steve)
Sun Dec 6 14:35:33 CET 2009 1.86
Mostly a bugfix release. Two new features. First the ability to exclude directories from an appmod. This is especially interesting for users that have an appmod at '/' but still want yaws to ship normal static contet such as js files and images. Secondly support for Forward proxying was added. Here is the changes list:
It wasn't possible to handle huge files (above 2GIG ?) If sendfile hits EOVERFLOW send the file from Erlang code instead (Steve and klacke)
json binary key support (TBBle)
Forward proxy functionality added through a patch by Colm Dougan
patch from anders dahlin to always populate yaws auth headers
Added SSL support to stream_process_* functions. (davide)
Added support for passing SSL configurations to start_embedded as a proplist (passing #ssl{} still works). (davide)
Added support for excluding dirs from an appmod. (klacke)
erasing the connection header must also set doclose to false (steve)
Several soap patches by Eric Liang. docs, support on addtional specified prefix when rpc call by method: yaws_soap_lib:call, add the soap_srv_mods support, which can setup soap serve modules while yaws start.
prevent crash caused by malicious client sending an empty Host header (steve)
Several haXe fixes by Paul Hampson - Add example for haXe returning an error object, Document how to run haXe remoting sample under neko, Export haXe remoting handler function, Add example for JSON-RPC returning an error object, Allow JSON-RPC/haXe remoting handlers to send error objects.
yaws_rpc produced non-compliant jsonrpc results. Looking at the JSON-RPC specification at the returned result of a call needs to contain an error field, with value null for the success case. The example json-rpc python client code on the site expects this field to be present. (TBBle)
Allow binaries as json values. (Matt Stancliff)
mkcert SSL scripts (klacke)
Sat Oct 17 22:56:36 CEST 2009 1.85
This is mostly (again) a bugfix/minor enhancement release.

add --nodebug option (steve)
determine gcc flags for 32-bit or 64-bit Erlang on OS X Snow Leopard (steve)
add new multipart example yaws_multipart.erl (Praveen Ray)
timezone format patch by Per Hedeland
Patch from wde with support for virthosting several ssl serveres on the same IP. This makes sense if we have multiple subjectAltName in the ssl cert
fixes for FCGI authorization (Bruno Rijsman), plus I cleaned up indentation and comments in yaws_cgi.erl
Sun Jul 5 20:05:00 CEST 2009 1.84
patch from anders abramhamson - a bug with multipart posts
New stats feature added by Olivier Girondel whereby (optionally) stats is collected for a virt server. Stats available from comand line (yaws --stats). There are also plugins for munin to graph the statistics.
The authmod code should now be backwards compatible (faal)
fixes for traffic tracing in reverse proxy mode (Olivier Girondel)
Better error msg if erl is not found for win32 users (klacke)
eliminate io_lib:format overhead in yaws_log:fmtnow (Steve)

removed ancient backwards compat flag (klacke)
Thu May 28 20:17:10 CEST 2009 Yaws 1.82
Have the yaws script set HOME if unset, this is required since some distros (Ubuntu) don't set HOME for code run under/etc/rc and erlexec requires HOME to be set. (Klacke)
add extra cgi vars patch from joe_e_e
new ebuild file for gentoo from joe_e_e
patch by joe_e_e to move all files from /etc to /etc/yaws in the install script. This may cause some troubles for some users when upgrading. By default the make install target doesn't overwrite /etc files. Pay attention.
added sendfile check for Darwin, since no sendfile is available on OS X Tiger (Steve)
RSS fixes, (Steve)
Several authentication fixes by Fabian Alenius. Changed the way authentication is done, added support for multiple authentication methods to be used for one directory and changed so that the 401 page can be customized similarly to the 404 page. In general this is a major cleanup of how authentication is done. Much better. One backwards incompat change here. Fabian Renamed yaws_401.erl to yaws_outmod.erl, which is probably a better name considering it's current use(it also displays the crashmsg). We need some better docs describing authentication !!!
add date header to OPTIONS response (Steve)
fix badmatch calling yaws_server:suffix_type from yaw_server:do_url_type when dav is true (Steve)
Added fix and tests for github issue #2. Handle zero values for max_num_cached_files, max_num_cached_bytes, and max_size_cached_file to prevent infinite loops. (Steve)
modify time_to_string to avoid slow io_lib:format (Steve)
added sendfile check for Darwin, since no sendfile is available on OS X Tiger (Steve)
document rss_dir (Steve)
add ets-based yapp registry implementation for cases where mnesia is overkill (Steve)
Fixed so that the HTTP status is set to 401 explicitly in yaws_server:handle_ut(...), previously out401 needed to return {status, ...} or status would default to 200. (Fabian Alenius)
Mon Mar 9 21:48:18 CET 2009 Yaws 1.81
Moved the Yaws repository to http://www.github.som. See instructions at on how to git clone Yaws. This is the first yaws release out of the github repo. The default Yaws wiki previously found at has been moved to the wiki at github. New address of wiki is The previous (Erlang based wiki written by Johan Bevemyr) turned ... well unmodern, and was also plagued by spammers.
Several cleanups by Hans Ulrich Niedermann, file perms, speling errors etc.
remove leading slash in yapp_appmods examples (Tom McNulty)
Add DIME support for SOAP Anders Nygren
patch by Jouni Ryno finding broken fdsrv support
Two patches by Joseph Wayen Norton, one dbg-bug and one providing better cookie support for yaws sesssions
When yaws_ctl checks the CTL file to see if any current instance is running, check the socket opened to the port read from the CTL file to verify that the ephemeral port for that socket is not the same as the port read from the CTL file. This avoids a false positive caused by connecting the socket to its own port. (Steve Vinoski)
cleaned up the redirect feature. It was poorly implemented and poorly documented. This fix is backwards compatible for users using redirect in confd.conf. However, it is NOT backwards compatible for embedded users that specify the redirect_map explicitly in their #sconf{} records. The required changes for embedded users should be evident from the code. The new required format is documented in the code where #sconf{} is defined (klacke)
Thu Feb 12 22:58:16 CET 2009 Yaws 1.80
Full windows support with a proper .exe Windows installer (klacke)
Added a timestamp check on the ssl cert/key files making it possible to just upload new cert/key files and do yaws --hup to automatically have the new cert/key files being used (klacke)
Disgusting DOS attack discovered by Manuel Duran Aguete whereby if a neverendig series of headers are sent to yaws, we die of out of memory. Actual attack not described here. Contact me (klacke) if you're interested in the details and want a backport patch. I'm not really sure this is indeed the right procedure for announcing a DOS bug. (First time !!!)
init_db patch cleanup by Liu Yubao
patch by Liu Yubao to remove timeout in ssl accept

Implement special handling of the '*' URI for the OPTIONS method as specified in RFC2616 section 9.2. (vinoski)
Added more thorough support for the HTTP OPTIONS method. For "active" applications such as appmods and yapps, the OPTIONS method is delivered through to the application for processing. For "passive" resources such as files and directories, OPTIONS returns a canned response just as before. (vinoski)
added redirect_self() to yaws_api (klacke)
yaws.rel.src was missing and better error printuts when yaws.conf is missing, patch by Vance Shipley

added mnesia_dir support to the gconf record as per patch BY Richard Bucker
The supervisor args were wrong, yaws shall have 1,0 restart strategy. This may break some backwards compat. Sites that ues yaws embedded need to check this.
Added debug dump functionality (klacke)
cygwin install patch by Bill Robertsson
Adding files for Erlware. A very rough packaging of 1.76 has been released at See the doc/overview.edoc for more details. (tobbe)

Sloppy ssl bug found by John Webb
Wed Sep 19 23:17:47 CEST 2007 1.72
Even more bad properties found. Now all png, gif and wob (those are for the wiki) files have svn:mime-type application/octet-stream and no other properties. Finally fixed I hope.

Regular bugfix and small feature release.
Revproxy bug found by igor goryachev.
Started to use the new ssl:transport_accept() function, when accept fails, We now fail yaws entirely and it needs to be restarted by its supervisor or heart. If we have filedescriptor leaks, even outside of yaws, there is no good thing to do when accept fails. (klacke)

RSS The generated content was not valid RSS 2.0 content (tobbe)
added ability to have config files in several files, patch from Sergei Golovan.

Mon Sep 11 19:59:57 CEST 2006 version 1.65
patch by Chris NewCombeto handle PUT method better.
Yapp added. Yaws application (Yapp) handler in yaws/applications/yapp directory "Drops" web applications independently of each other into an existing server where they get the default URL http://servername/application_name/. Yapps are simply Erlang/OTP applications with web pages in their priv/docroot directory (default). One can also configure private appmods, useful for controller parts in MVC like applications. (Mikael Karlsson)
Haxe. Now compatible with the latest version of haXe. (yarivvv)
New support to start Yaws as in embedded mode without having to fiddle with the boot script (etnt)
patch from Matthew Reilley to handle new backwards non-compatible return value from OTP zlib:deflate/4
patch from anders nygren to handle absolute paths + yssi.
patch from Magnus froberg to get better control over the files generated by 'yaws --check'. This is good if one wants to run i.e. xref and dialyzer also on all the generated .erl files from the --checker.
empty array bug in json parse found by juhani and fixed by gaspar.
appmod '/' was broken (klacke)
Install, netbsd/ NetBSD support from Kuzma Bartosz.

JSON Ajax code from Gaspar Chilingarov, I added docs describing an example. (klacke)
run_erl and to_erl support patch from Mats Cronquist.
yaws_zlib.erl: some bugs in non used code found by dialyzer.
small fixes in the start script code (klacke)
Fixes from Mikael Karlsson adding an event manager to Yaws whereby it is possible to add user defined gen_event handlers handling different "events" from Yaws. The only event sofar is config changes. This is needed for mikls "yapp" project which is a way to write yaws packages that can be "dropped" into an existing server. (No docs or anything released yet)
Thu Apr 27 21:40:01 CEST 2006 Version 1.61
Started to write the ctl file, the file which contains the portnumber where the daemon is listening for ctl command to - /var/run/yaws/ctl-${ID}. The location is controllable through configure. Install scripts will make the /var/run/yaws dir writable to the world, each individual daemon which creates the ctl file will explicitly set the permissions on the ctl file to 600 - thus making it impossible for unauthorized users to control someone elses daemon. Root can control all daemons.
changed Yaws license to proper BSD (klacke)
Added startup script for FreeBSD
Worked the Makefiles to properly support DESTDIR. This is useful for packagers creating deb, rpm, portage ... packages (klacke)
Removed the ability to change userid. Also stopped writing to /tmp/yaws and started to write to ${HOME}/.yaws instead. This is much better since we cannot now ever get into the situations where file ownership and umask stop us from controlling a daemon. Note, this is a backwards incompatible change, all users that used the feature of letting Yaws change uid need to start using fdsrv instead. There is also a configurable in yaws.conf which makes it possible to write the tmp files to some other directory (klacke)
Cleaned up the start flags to the yaws script, all old flags are still there for backward compatibility. Updated docs and and help output from the yaws script to reflect all new flags.
Wiki fixes. Fixed error printouts; handle https and ftp links; updated READE (mbj)
file descriptor leak bug found by Mats Cronqvist where each call to 'yaws -ls' left an unclosed descriptor in the server (klacke)
Source code cleanup - added and #env record for environment passed to yaws. (klacke)
yaws_ls enhancements by
Wed Feb 1 23:28:42 CET 2006 Version 1.58
pam and setuid_drv fixes for BSD by sstrollo
yaws_ls (dir listing) enhancements by
RSS updates, more docs, Made month and days in RSS output to consist of two figures instead of just one. Fixed the RSS date format, as suggested by Daniel Kaminski. (Tobbe)
Wiki, Fixed path to the application directory where yaws files are stored. (mikl)
Added feature to not pick first sconf when virthosting. This is essential if we want explicit control over the virt hostnames. A commercial site called don't want to ship the pages of the serious site :-) (klacke)
DAV - reworked the DAV support a bit - don't use an appmod, instead yaws has built-in support for DAV methods. Added support for missing DAV methods (COPY etc). (mbj)
Added support for the erlmerge/jungerl package 'fdsrv' which makes it possible to bind to privileged ports < 1024 even when we're not running as root. (klacke)
changed so that an arg_rewrite_mod may temporarily change the docroot by changing the Arg#arg.docroot attribute (mikl)
Added "pam" support for HTTP auth. (klacke)
Wed Aug 17 14:54:06 CEST 2005 Version 1.57
rel/abs path patch by Rob Schmersel which fixed a problem in the wiki
Rewrote yaws SSL code to use the packet http and packet line modes that are now supported in the OTP ssl module. Earlier this was all manual (and slow) code in yaws. Thus yaws/SSL servers are now considerably faster. The old yaws_ssl modules is no longer used. (klacke)
Support clients that POST data with Transfer-Encoding chunked. This is used by some models of cellphones. Bug found by (Klacke)
Tmp dir patch by Karel Ostrovsky to better support tmp dir on Windows
cgi port patch by joe_e_e
Do not send the server port along with the host name in the CGI HTTP_HOST environment variable. Added HTTP_HOST env variable for CGI scripts (was required by sphpblog). (mikl)
Thu Jun 16 13:42:50 CEST 2005, Version 1.56, Security update release.
A bug was found by Daniel Fabian, SEC-Consult Unternehmensberatung GmbH whereby: If a null byte is appended to the filename of a yaws script (.yaws), the yaws webserver returns a page containing the source code of the according script. This flaw allows a malicious attacker to analyse the source code of the entire web application, which might result in the attacker gaining sensitive information like passwords. All versions of yaws older than 1.56 are vulnerable.
For users running old yaws web servers, the following <a href="yaws-1.55_to_1.56.patch"> patch </a> can be applied. The patch is small and can easily be back ported to older yaws releases.
Fri Jun 10 16:09:58 CEST 2005, Version 1.55 released. Feature release.
Concept of redirect maps added. See documentation in yaws.conf man page. This makes it possible to redir entire parts of the docroot to another site (jb)
Removed the forbidden code, the right thing to do when a script type is forbidden and we shall not run an interpreter on the script is to ship the script, but as text/plain instead of actually refusing to ship the data. Otherwise it's not possible to publish .php files at all on the web site. (klacke)
Initial support for Web DAV added. This is as of yet undocumented. (tobbe)
Added the possibility to have multiple docroots, where a page is searched in the list of docroots (klacke)
Tue Apr 12 2005, Version 1.54 released. Bugfix release.
Bug in SSL fixed, Bad line parsing in SSL mode, crashed when client sent headers split up in a certain way. (klacke)
Removed the automatic htmlize on strings in ehtml, it was wrong ... to have it there. It's better for users that want it to explicitly add yaws_api:htmlize() to their strings This breaks code and is non backwards compatible. Be aware !! Also made {Tag, Attr} generate xhtml compliant code. (klacke)
Cleaner shutdown (klacke)
Many improvements to the chat server. (jb)
When clearing the cache, yaws modules would remain loaded but be forgotten, resulting in a memory leak. (cschultz)
Added possibility to name the module in a .yaws file using a syntax of < erl module="foobar"> .... < /erl> to always get a .yaws file named to a special fixed module name instead of the increasing m1,m2 .. modulenames. This is useful if we want to keep API functions in certain .yaws files and call these functions from other .yaws files. (klacke)
Many reverse proxy bugs fixed. Maybe the reverse proxy is actually working now. It was never especially good. Try it. (mikl)
Bug fixed with bindings that got propagated over to other later requests.Yet another put/get bug. Maybe it's time for an acronym there. YAPGB ??? (klacke)
Better looking debug printouts. + dont overwrite trace_to_tty (-x commandline) if set on the commandline and also in the config file. Commandline should have precedense over config file directives. (klacke)
Wrote an internals document. Available at <a href=""></a> (klacke)
Fri Feb 18, 2005 Bugfix release
Fatso bug found by Fredrik Linder where yaws completely crash on bad URLs that for example contain space chars in the uri. This is the bug which provoked this imideate followup release. (klacke)
Removed old broken URL decode code which was wrong. This code was added befor we actually understood how URLs are en/de coded (klacke, jb)
Added example chat program (jb)
Added new config opt fail_on_bind_err = Bool. The old behaviour was to silently accept (and log) server startup errors. This was due to a request from Tony Rogvall and the behaviour is bad, it's now back to the original behaviour where the entire yaws "application" fails if one virt server fails to gen_tcp:listen().
Mon Feb 14 2005, Version 1.52 released
Minor feature release
error condition bug in revproxy, found by tobbe. Revproxy is still not production quality. Experimental.
embedded bugfix by Michael Arnoldus
connection close bug found by Lennart Ostman
made errorlog actually go out when conf is brokbroke e + daemon (klacke)
Yaws is now RSS capable, see doc/README.rss (tobbe)

wiki, Fixed minor unzip problem triggered when uploading zip archives with names containing spaces. (jb)
Wed Dec 15 2004 Version 1.51 released
Major feature release.
Added support for config changes without stopping the running systems, virt servers can be added, removed and changed without affecting traffic. (klacke)
wiki/searchPage.yaws: Added search code from Jouni Ryno (jb)
Added client IP resolv for access log files (klacke)
Safer make install target. Can't install if yaws is running (klacke)
Updated both mail and wiki according to changed APIs for parse_multipart. (jb)
Sat Dec 11 2004 Version 1.50 released
Bugfix and docs release
Running the wiki at the yaws site. Use it !!. No passwords....
<verbatim> tag added, this tag pretty much works as <pre> _should_ have worked. Nothing needs to be escaped, and code containing <, >, & etc can be entered freely. Writing code examples were driving me crazy. Inside both <pre> and <code> tags all HTML special chars have to be quoted, sucks. (klacke)
Rewamped all docs with CSS and XHTML 1.0, beautiful and nice (klacke)
Attach file problem in wiki (jb)
Form post parameter was still always managed as atoms. This is a backwards incompatible change. It broke the wiki aswell as the upload example in the Yaws docs.However, the change is sound since it was easy to DOS a yaws server by sending file upload posts with new atoms. Eventually the atom table would overflow. However it does break code !!! (mikl)
Added auto-generate to dir listings. It needs the zip command in the current path to function properly. To turn off, use dir_listsings = true_nozip. This is a feature for all of us that like to share copyrighthed material to friends that can't muster wget -r (mbj)
Added relative path to ssi, ie {ssi, {rel_path, File}, ...} is now possible. (jb)
mail app, Fixed refresh bug. (jb)
Added example docs on how to stream data (klacke)
modded patch by sebastian strollo to let request_url/1 and reformat_url/1 be proper inverses of each other (klacke)
Made upgrading to new style Wiki templates smooth. If no template.html file exists in the WikiPreferences.files directory, then one is created. The same goes for template_info.html. (jb)
Thu Sep 2, 2004 Version 1.49 released
Webmail fixes by jb, Add original message quoted in reply, Delete email bug fixed, Mailbox already locked bug, Improved attachment handling.
Wiki fixes by jb, Made layout of wiki much more configurable using templates and ssi. You must run the script/updateWiki script after updating to this release.
Bug found by David Welton, url on the form had yaws_api:queryval/2 return {nokey, "foo"} which is clearly wrong. New correct val is {"foo", undefined}.
two-mode.el contributed by David Welton. Makes it easier to edit files with both erlang and html content. Typically the case for yaws files.
cschultz did lots of stuff, Deflate rehaul: Now works with dynamic pages, Multiple dots in yaws file name caused trouble with pathinfo, fixed silly bug with content-range, cache fixes, Have several processes wait for SSL connections, so that one SSL negotiation in progress does not prevent other connections. Also, for the similar reasons, have use a timeout with SSL accepts. timeout are quite arbitrary. They are ok for my low traffic site. Streaming fixes, Rewrite requests with absolute URI to look like requests with a Host header.
Small fix with embedded mode (it was completely non-working) by Jimmy Olgeni
Addded configure option -with-defaultcharset (klacke)
jb fixed a severe bug in ssi, Fixed bug in ssi code. Multichar delims were not handled properly. When a char of the delim string was found in the text it was deleted.
patch from Paul Mahon to add PEER_ADDR to cgi env
Mon Jun 7, 2004 Version 1.48 released
This release contains both bugfixes as well as som minor new features. There was also a fairly ugly security hole in the example code which describes file uploads found and fixed.
A Bug in yaws_api:request_url/1 was found by Einar Karttunen. The function didn't handle well the case with explicit port numbers in the URI. (klacke)
Fixed the appmod code so that users of yaws_api:setconf/1 doesn't have to bother with the cahnge in internal representation of appmods. (klacke)
Moved phpexe config variable from the sconf to the gconf, it doesn't make sence to have different phpexe paths for different virt servers. Users with old configs will get a warning when tying to specify a phpexe inside a virt server instead of inside the global config area. (klacke)
New feature called "yssi". Yaws server side include. It's now possible to let the out/1 function return a tuple {yssi, PathToYawsFile.yaws"}. The new yaws file will be fully expanded, compiled and in general handled as a yaws file. This feature can probably be used to build all kinds of different cool stuff. (klacke)
yaws_session_server ttl patch from Rob.Schmersel
Patch from Fredrik Linder to make it easier to integrate yaws into apps that don't use the otp application framework at all.
As usual updates both to the wiki and the webmail app by (jb)
Patch from Jocke Grebeno which handles ssi support for ehtml code, not just ascii. We can now return {ssi, "@@", file.html, [{"FOO", "bar"}, {"BAZ", {ehtml, {p, [], "saab"}}}]} and it returns the expected. Documented is ssi.yaws.
Security vulnerability in upload.yaws found by (mbj)
Thu May 27, 2004 Version 1.47 released

Embedded mode fixes (Jimmy Olgeni)
Don't create no logs at all when logging is turned off bugfix (Jimmy Olgeni)
SSL and large POSTs fix (cschultz)
Compression and keep alive fix (cschultz)
As usual, several fixes to the wiki and the webmail app (jbevemyr)
An XSS vulnerability (lpsmith)
Rewrote the url spliting (again) and also backed off from the redir when we get and index.html exists. It's better to ship the file directly instead of sending a redir. (klacke)
Reworked (and documented) the appmods a bit (klacke)
Added a command line flag (yaws -ls) which lists existing yaws servers and their status on localhost. (klacke)
Fri Apr 16, 2004 Version 1.45 released
Minor bugfix release fixing up the some odd bugs introduced in the 1.43 rewite.
Mar 18, 2004 Version 1.43 released
This is a major release. Not so much for added functionality as for internal rewrites of the code. The release contains the following:
Compression support using zlib. Still experimental. (cschultz)
Minor bugfixes in the reverse proxy. This code is still not ready (klacke)
Added a specific auth log which logs good and bad HTTP auth requests.
QNX port (
Beautification of dir listings (cschultz)
Never let ehtml generate extra spaces where it is not entirely correct (patch from tomas abrahamsson)
Webmail app, Completed support for attachments, proper esacping, faster listing of large mboxes. Added sorting of mails (jb)
Date header bug (chandru)
postvar put/get bug fixed (hal snyder)
Added yaws_api:query_url(Arg) which reconstructs the url from the original GET request.
Added the "id = Key" configuration parameter. Earlier when we were running multiple yaws servers on the same machine, they had to run with different uid since yaws was writing temporary files under /tmp/yaws/${uid}. This is now changed and if we want 2 _different_ yaws servers on the same machine they must be given different "id" in their respective config files. The yaws ctl scripts, such as yaws -s and friends now have an extra (optional) "-j id" flag to control which specific instance of Yaws is ment.
Added explicit support for Content-Length header from .yaws files for applications that require Content-Length instead of chunked encodings.
Changed the #sconf{} and #gconf{} records so that all the booleans in those 2 records are now a bitmask flag. This is a slightly backwards incompatible change and it affects those that use Yaws in embedded mode where the #sconf and #gconf records are explicitly manipulated. It sholdn't be a big deal to change though.
Workaround buggy otp error_logger_file_h which truncates the report file whenever it is reopened.
Removed the calls inside the server that were doing list_to_atom/1 We were suceptible to DOS attacks. This is unfortunately a backwards incompatible change since it affects the return value from API functions yaws_api:parse_query/1 and yaws_api:parse_post/1. They both used to return lists on the form of {Key, Val} tuples where Key was an atom. It is now a string. There is a configuration option for yaws.conf which keeps the old (broken) behaviour.
Optimized url parsing and removed at least one call to lists:flatten/1 in the fast path.
Better support for old Netscape and the Connection: Keep-Alive header.
More beautiful trace output. Try "yaws -i -x -T"
More and better debug support.
New install procedure with a more interesting yaws.conf template generated.
Updated the ssl test certs that come with yaws. The old ones had expired.

Added proper support for 'if-none-match' with etag matching by Johan Bevemyr
Skip empty space after an erl chunk in a .yaws file

Return status 303 when browser asks for a dir URL without a trailing / in the http request. I've always wondered why apache does this. Now I know ... otherwise the relative URLs in /dir/index.html will be wrong when the browser tries to get them. Utilize this feature when listing dirs now, generate relative urls instead of absolute.
Removed the default_server_on_this_ip option, the first virthosted server in the config will be default if no Host: header is present
Made the Host: check to check for Host: host:port instead of just host when a server is run on a non-standard port. The browsers seem to set the Host: field to host:port
Tobbe added the -r flag to the startscript
Changed yaws_api:parse_post_data/1 so that it takes an arg struct as argument instead of querydata and added support for multipart form data in the process.
