|
<p>Except for the optimizations and the additional <directive
|
|
module="mod_cgid">ScriptSock</directive> directive noted below,
|
|
mod_cgid behaves similarly to mod_cgi. <strong>See the
|
|
<module>mod_cgi</module> 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
|
|
<module>mod_cgi</module>. 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>

<usage>
|
|
<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>
