<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>

<p>This directive sets the filename prefix of the socket to use for
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
scripts, it is important that no other user has permission to
write in the directory where the socket is located.</p>
