97a9a944b5887e91042b019776c41d5dd74557aferikabele <p>Except for the optimizations and the additional <code class="directive"><a href="#scriptsock">ScriptSock</a></code> directive noted below,
06ba4a61654b3763ad65f52283832ebf058fdf1cslive mod_cgid behaves similarly to mod_cgi. <strong>See the
97a9a944b5887e91042b019776c41d5dd74557aferikabele <code class="module"><a href="/mod/mod_cgi.html">mod_cgi</a></code> Summary for additional details about
06ba4a61654b3763ad65f52283832ebf058fdf1cslive <p>On certain unix operating systems, forking a process from a
06ba4a61654b3763ad65f52283832ebf058fdf1cslive multi-threaded server is a very expensive operation because the
06ba4a61654b3763ad65f52283832ebf058fdf1cslive new process will replicate all the threads of the parent
06ba4a61654b3763ad65f52283832ebf058fdf1cslive process. In order to avoid incurring this expense on each CGI
06ba4a61654b3763ad65f52283832ebf058fdf1cslive invocation, mod_cgid creates an external daemon that is
06ba4a61654b3763ad65f52283832ebf058fdf1cslive responsible for forking child processes to run CGI scripts. The
06ba4a61654b3763ad65f52283832ebf058fdf1cslive main server communicates with this daemon using a unix domain
06ba4a61654b3763ad65f52283832ebf058fdf1cslive socket.</p>
136489fb8f0fe36dbcad3064a335eb86bfbeb5c6rbowen <p>This module is used by default instead of
97a9a944b5887e91042b019776c41d5dd74557aferikabele <code class="module"><a href="/mod/mod_cgi.html">mod_cgi</a></code> whenever a multi-threaded MPM
06ba4a61654b3763ad65f52283832ebf058fdf1cslive is selected during the compilation process. At the user level,
06ba4a61654b3763ad65f52283832ebf058fdf1cslive this module is identical in configuration and operation to
97a9a944b5887e91042b019776c41d5dd74557aferikabele <code class="module"><a href="/mod/mod_cgi.html">mod_cgi</a></code>. The only exception is the
06ba4a61654b3763ad65f52283832ebf058fdf1cslive additional directive <code>ScriptSock</code> which gives the
06ba4a61654b3763ad65f52283832ebf058fdf1cslive name of the socket to use for communication with the cgi
06ba4a61654b3763ad65f52283832ebf058fdf1cslive daemon.</p>

06ba4a61654b3763ad65f52283832ebf058fdf1cslive using the permissions of the user who starts Apache (usually

06ba4a61654b3763ad65f52283832ebf058fdf1cslive scripts, it is important that no other user has permission to
