| <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> |
