In order to avoid incurring this expense on each CGI invocation, <code class="module"><a href="../mod/mod_cgid.html">mod_cgid</a></code> creates an external daemon that is responsible for forking child processes to run CGI scripts. The main server communicates with this daemon using a unix domain socket.</p> <p>This module is used by default instead of <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code> whenever a multi-threaded MPM is selected during the compilation process. At the user level, this module is identical in configuration and operation to <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code>. The only exception is the additional directive <code>ScriptSock</code> which gives the name of the socket to use for communication with the cgi daemon.</p> </div> <div id="quickview"><a href="https://www.apache.org/foundation/contributing.html" class="badge"><img src="https://www.apache.org/images/SupportApache-small.png" alt="Support Apache!" /></a><h3 class="directives">Directives</h3> <ul id="toc"> <li><img alt="" src="../images/down.gif" /> <a href="#cgidscripttimeout">CGIDScriptTimeout</a></li> <li><img alt="" src="../images/right.gif" /> <a href="mod_cgi.html#scriptlog">ScriptLog</a></li> <li><img alt="" src="../images/right.gif" /> <a href="mod_cgi.html#scriptlogbuffer">ScriptLogBuffer</a></li> <li><img alt="" src="../images/right.gif" /> <a href="mod_cgi.html#scriptloglength">ScriptLogLength</a></li> <li><img alt="" src="../images/down.gif" /> <a href="#scriptsock">ScriptSock</a></li> </ul> <h3>Bugfix checklist</h3><ul class="seealso"><li><a href="https://www.apache.org/dist/httpd/CHANGES_2.4">httpd changelog</a></li><li><a href="https://bz.apache.org/bugzilla/buglist.cgi?bug_status=__open__&list_id=144532&product=Apache%20httpd-2&query_format=specific&order=changeddate%20DESC%2Cpriority%2Cbug_severity&component=mod_cgid">Known issues</a></li><li><a href="https://bz.apache.org/bugzilla/enter_bug.cgi?product=Apache%20httpd-2&component=mod_cgid">Report a bug</a></li></ul><h3>See also</h3> <ul class="seealso"> <li><code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code></li> <li><a href="../suexec.html">Running CGI programs under different user IDs</a></li> <li><a href="#comments_section">Comments</a></li></ul></div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="directive-section"><h2><a name="CGIDScriptTimeout" id="CGIDScriptTimeout">CGIDScriptTimeout</a> <a name="cgidscripttimeout" id="cgidscripttimeout">Directive</a></h2> <table class="directive"> <tr><th><a href="directive-dict.html#Description">Description:</a></th><td>The length of time to wait for more output from the CGI program</td></tr> <tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>CGIDScriptTimeout <var>time</var>[s|ms]</code></td></tr> <tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>value of <code class="directive"><a href="../mod/core.html#timeout">Timeout</a></code> directive when unset</code></td></tr> <tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host, directory, .htaccess</td></tr> <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr> <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_cgid</td></tr> <tr><th><a href="directive-dict.html#Compatibility">Compatibility:</a></th><td>CGIDScriptTimeout defaults to zero in releases 2.4 and earlier </td></tr> </table> <p>This directive limits the length of time to wait for more output from the CGI program.
