41 <p>On certain unix operating systems, forking a process from a
42 multi-threaded server is a very expensive operation because the
43 new process will replicate all the threads of the parent
44 process. In order to avoid incurring this expense on each CGI
45 invocation, <code class="module"><a href="../mod/mod_cgid.html">mod_cgid</a></code> creates an external daemon that is
46 responsible for forking child processes to run CGI scripts. The
47 main server communicates with this daemon using a unix domain
50 <p>This module is used by default instead of
51 <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code> whenever a multi-threaded MPM
52 is selected during the compilation process. At the user level,
53 this module is identical in configuration and operation to
54 <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code>. The only exception is the
55 additional directive <code>ScriptSock</code> which gives the
56 name of the socket to use for communication with the cgi

84 <p>This directive sets the filename prefix of the socket to use for
85 communication with the CGI daemon, an extension corresponding to
86 the process ID of the server will be appended. The socket will be opened
87 using the permissions of the user who starts Apache (usually
88 root). To maintain the security of communications with CGI
89 scripts, it is important that no other user has permission to
90 write in the directory where the socket is located.</p>
