6414b7c981378a6eef480f6806d7cbfc98ca22a1David Strauss <p>Except for the optimizations and the additional <a class="directive" href="#scriptsock"><code class="directive">ScriptSock</code></a> directive noted below,
mod_cgid behaves similarly to mod_cgi. <strong>See the
<code><a href="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, mod_cgid 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 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><a href="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 name of the socket to use for
communication with the CGI daemon. 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>
