1377N/A <p>Except for the optimizations and the additional <a class="directive" href="#scriptsock"><code class="directive">ScriptSock</code></a> directive noted below,
1377N/A mod_cgid behaves similarly to mod_cgi. <strong>See the
1377N/A <code><a href="mod_cgi.html">mod_cgi</a></code> Summary for additional details about
1377N/A Apache and CGI.</strong></p>
1377N/A
1377N/A <p>On certain unix operating systems, forking a process from a
1377N/A multi-threaded server is a very expensive operation because the
1377N/A new process will replicate all the threads of the parent
1377N/A process. In order to avoid incurring this expense on each CGI
1377N/A invocation, mod_cgid creates an external daemon that is
1377N/A responsible for forking child processes to run CGI scripts. The
1377N/A main server communicates with this daemon using a unix domain
1377N/A socket.</p>
1377N/A
1377N/A <p>This module is used by default whenever a multi-threaded MPM
1377N/A is selected during the compilation process. At the user level,
2282N/A this module is identical in configuration and operation to
1377N/A <code><a href="mod_cgi.html">mod_cgi</a></code>. The only exception is the
1377N/A additional directive <code>ScriptSock</code> which gives the
1377N/A name of the socket to use for communication with the cgi
1377N/A daemon.</p>

1377N/A <p>This directive sets the name of the socket to use for
1377N/A communication with the CGI daemon. The socket will be opened
1377N/A using the permissions of the user who starts Apache (usually
1377N/A root). To maintain the security of communications with CGI
1377N/A scripts, it is important that no other user has permission to
1377N/A write in the directory where the socket is located.</p>
