CGI.pm is a stable, complete and mature solution for processing and preparing HTTP requests and responses. Major features including processing form submissions, file uploads, reading and writing cookies, query string generation and manipulation, and processing and preparing HTTP headers. Some HTML generation utilities are included as well.
CGI.pm performs very well in in a vanilla CGI.pm environment and also comes with built-in support for mod_perl and mod_perl2 as well as FastCGI.
It has the benefit of having developed and refined over 10 years with input from dozens of contributors and being deployed on thousands of websites. CGI.pm has been included in the Perl distribution since Perl 5.4, and has become a de-facto standard.
