FastCGI | FastCGI -About FastCGI FastCGI is simple because it is actually CGI with only a few extensions. Like CGI, FastCGI is also language-independent. For instance, FastCGI provides a way to improve the performance of the thousands of Perl applications that have been written for the Web. Like CGI, FastCGI runs applications in processes isolated from the core Web server, which provides greater security than APIs.
