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

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