+<h3>Summary</h3>
+
+ <p>Except for the optimizations and the additional <code class="directive"><a href="#scriptsock">ScriptSock</a></code> directive noted below,
+ <code class="module"><a href="../mod/mod_cgid.html">mod_cgid</a></code> behaves similarly to <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code>.
+ <strong>See the <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code> summary for additional details
+ about Apache and CGI.</strong></p>
+
+ <p>On certain unix operating systems, forking a process from a
+ multi-threaded server is a very expensive operation because the
+ new process will replicate all the threads of the parent
+ process. 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>

+ communication with the CGI daemon, an extension corresponding to
+ the process ID of the server will be appended. The socket will be opened
+ using the permissions of the user who starts Apache (usually
+ root). To maintain the security of communications with CGI
