mod_fcgid is a high performance alternative to mod_cgi or mod_cgid, which starts a sufficient number instances of the CGI program to handle concurrent requests, and these programs remain running to handle further incoming requests. It is favored by the PHP developers, for example, as a preferred alternative to running mod_php in-process, delivering very similar performance.

The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the release of version 2.3.6 of mod_fcgid, a FastCGI implementation for Apache HTTP Server versions 2.0, 2.2, and future 2.4. This version of mod_fcgid is a bug fix release.

A fix is included for CVE-2010-3872, a potential vulnerability which can affect sites with untrusted FastCGI applications.

Additionally, default configuration settings for request body handling have been changed to prevent large system resource use. Administrators of all versions of mod_fcgid are strongly cautioned to ensure that FcgidMaxRequestLen is configured appropriately.

The mod_fcgid reference page will get you started.

See the README-FCGID file distributed with the module's source code for additional build and installation notes.

Discussions of mod_fcgid take place on the Apache HTTP Server mailing lists, including the following:

• User support and discussion
• Development discussions
• svn commit logs for httpd, including mod_fcgid

mod_fcgid was created by Ryan Pan (Pan Qingfeng, pqf or 潘庆峰) in 2004 as a new FastCGI implementation, and was granted to the ASF as an Apache HTTP Server subproject in 2009, shepherded by Chris Darroch (chrisd).
