Perl (Practical Extraction and Report Language) is a scripting language that is often used for CGI programming. Perl is freely available.
FastCGI support is available for Perl via the FCGI.pm Perl module. FCGI.pm no longer requires SFIO or a specially-built Perl. FCGI.pm is available via CPAN as well as in the perl directory of this kit.
Please see the FCGI.pm documentation for examples and details.
