This section provides an information overview of the Fast Common Gateway Interface (FastCGI) protocol, FastCGI applications and the FastCGI Web site. Links to related topics appear at the end of this section.
This third-party module provides support for the FastCGI protocol. FastCGI, a language independent, scalable, open extension to Common Gateway Interface (CGI), provides high performance and persistence without the limitations of server-specific APIs.
This open protocol does not limit FastCGI applications to a particular development language. FastCGI application libraries currently exist for Perl, C/C++, Java, Python and the transmission control layer (TCL).
FastCGI applications use TCP or UNIX sockets to communicate with the Web server. This scalable architecture enables applications to run on the same platform as the Web server, or on many machines scattered across an enterprise network.
You can port FastCGI applications to other Web server platforms. Most popular Web servers support FastCGI directly, or through commercial extensions.
FastCGI applications run fast because of their persistency. These applications require no per-request startup and initialization overhead. This persistency enables the development of applications, otherwise impractical within the CGI paradigm, like a huge Perl script, or an application requiring a connection to one or more databases.
