<!--
the iisnode section configures the behavior of the node.js IIS module
setting values below are defaults
* node_env - determines the environment (production, development, staging, ...) in which
child node processes run; if nonempty, is propagated to the child node processes as their NODE_ENV
environment variable; the default is the value of the IIS worker process'es NODE_ENV
environment variable
* nodeProcessCommandLine - command line starting the node executable; in shared
hosting environments this setting would typically be locked at the machine scope.
* interceptor - fully qualified file name of a node.js application that will run instead of an actual application
the request targets; the fully qualified file name of the actual application file is provided as the first parameter
to the interceptor application; default interceptor supports iisnode logging
* nodeProcessCountPerApplication - number of node.exe processes that IIS will start per application;
setting this value to 0 results in creating one node.exe process per each processor on the machine
* maxConcurrentRequestsPerProcess - maximum number of reqeusts one node process can
handle at a time
* maxNamedPipeConnectionRetry - number of times IIS will retry to establish a named pipe connection with a
node process in order to send a new HTTP request
* namedPipeConnectionRetryDelay - delay in milliseconds between connection retries
* maxNamedPipeConnectionPoolSize - maximum number of named pipe connections that will be kept in a connection pool;
connection pooling helps improve the performance of applications that process a large number of short lived HTTP requests
* maxNamedPipePooledConnectionAge - age of a pooled connection in milliseconds after which the connection is not reused for
subsequent requests
* asyncCompletionThreadCount - size of the IO thread pool maintained by the IIS module to process asynchronous IO; setting it
to 0 (default) results in creating one thread per each processor on the machine
* initialRequestBufferSize - initial size in bytes of a memory buffer allocated for a new HTTP request
* maxRequestBufferSize - maximum size in bytes of a memory buffer allocated per request; this is a hard limit of
the serialized form of HTTP request or response headers block
* watchedFiles - semi-colon separated list of files that will be watched for changes; a change to a file causes the application to recycle;
each entry consists of an optional directory name plus required file name which are relative to the directory where the main application entry point
is located; wild cards are allowed in the file name portion only; for example: "*.js;node_modules\foo\lib\options.json;app_data\*.config.json"
* uncFileChangesPollingInterval - applications are recycled when the underlying *.js file is modified; if the file resides
on a UNC share, the only reliable way to detect such modifications is to periodically poll for them; this setting
controls the polling interval
* gracefulShutdownTimeout - when a node.js file is modified, all node processes handling running this application are recycled;
this setting controls the time (in milliseconds) given for currently active requests to gracefully finish before the
process is terminated; during this time, all new requests are already dispatched to a new node process based on the fresh version
of the application
* loggingEnabled - controls whether stdout and stderr streams from node processes are captured and made available over HTTP
* logDirectory - directory name relative to the main application file that will store files with stdout and stderr captures;
individual log file names have unique file names; log files are created lazily (i.e. when the process actually writes something
to stdout or stderr); an HTML index of all log files is also maintained as index.html in that directory;
by default, if your application is at http://foo.com/bar.js, logs will be accessible at http://foo.com/iisnode;
SECURITY NOTE: if log files contain sensitive information, this setting should be modified to contain enough entropy to be considered
cryptographically secure; in most situations, a GUID is sufficient
* debuggingEnabled - controls whether the built-in debugger is available
* debuggerPortRange - range of TCP ports that can be used for communication between the node-inspector debugger and the debugee; iisnode
will round robin through this port range for subsequent debugging sessions and pick the next available (free) port to use from the range
* debuggerPathSegment - URL path segment used to access the built-in node-inspector debugger; given a node.js application at
http://foo.com/bar/baz.js, the debugger can be accessed at http://foo.com/bar/baz.js/{debuggerPathSegment}, by default
http://foo.com/bar/baz.js/debug
* debugHeaderEnabled - boolean indicating whether iisnode should attach the iisnode-debug HTTP response header with
diagnostics information to all responses
* maxLogFileSizeInKB - maximum size of a single log file in KB; once a log file exceeds this limit a new log file is created
* maxTotalLogFileSizeInKB - maximum total size of all log files in the logDirectory; once exceeded, old log files are removed
* maxLogFiles - maximum number of log files in the logDirectory; once exceeded, old log files are removed
* devErrorsEnabled - controls how much information is sent back in the HTTP response to the browser when an error occurrs in iisnode;
when true, error conditions in iisnode result in HTTP 200 response with the body containing error details; when false,
iisnode will return generic HTTP 5xx responses
* flushResponse - controls whether each HTTP response body chunk is immediately flushed by iisnode; flushing each body chunk incurs
CPU cost but may improve latency in streaming scenarios
* enableXFF - controls whether iisnode adds or modifies the X-Forwarded-For request HTTP header with the IP address of the remote host
* promoteServerVars - comma delimited list of IIS server variables that will be propagated to the node.exe process in the form of
x-iisnode-<server_variable_name> HTTP request headers; for a list of IIS server variables available see
http://msdn.microsoft.com/en-us/library/ms524602(v=vs.90).aspx; for example "AUTH_USER,AUTH_TYPE"
* configOverrides - optional file name containing overrides of configuration settings of the iisnode section of web.config;
the format of the file is a small subset of YAML: each setting is represented as a <key>: <value> on a separate line
and comments start with # until the end of the line, e.g.
# This is a sample iisnode.yml file
nodeProcessCountPerApplication: 2
maxRequestBufferSize: 8192 # increasing from the default
# maxConcurrentRequestsPerProcess: 512 - commented out setting
-->
<iisnode
configOverrides="iisnode.yml"
/>
<!--
One more setting that can be modified is the path to the node.exe executable and the interceptor:
<iisnode
nodeProcessCommandLine=""%programfiles%\nodejs\node.exe""
interceptor=""%programfiles%\iisnode\interceptor.js"" />
-->
