f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive <p>On certain unix operating systems, forking a process from a
9bcfc3697a91b5215893a7d0206865b13fc72148nd multi-threaded server is a very expensive operation because the
f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive new process will replicate all the threads of the parent
f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive process. In order to avoid incurring this expense on each CGI
f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive invocation, <code class="module"><a href="/mod/mod_cgid.html">mod_cgid</a></code> creates an external daemon that is
9bcfc3697a91b5215893a7d0206865b13fc72148nd responsible for forking child processes to run CGI scripts. The
f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive main server communicates with this daemon using a unix domain
f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive socket.</p>
9bcfc3697a91b5215893a7d0206865b13fc72148nd <p>This module is used by default instead of
9ed703ab1543b3300f4b60c0405fc1a212b601c8slive <code class="module"><a href="/mod/mod_cgi.html">mod_cgi</a></code> whenever a multi-threaded MPM
9ed703ab1543b3300f4b60c0405fc1a212b601c8slive is selected during the compilation process. At the user level,
9ed703ab1543b3300f4b60c0405fc1a212b601c8slive this module is identical in configuration and operation to
9bcfc3697a91b5215893a7d0206865b13fc72148nd <code class="module"><a href="/mod/mod_cgi.html">mod_cgi</a></code>. The only exception is the
f78ba66d5075af3e07e2d93aa7fa7b884836c6e8slive additional directive <code>ScriptSock</code> which gives the
