<H2>Summary</H2>
|
|
|
|
<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 <a
|
|
href="mod_cgi.html">mod_cgi</a>. 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>
