Most sites on the Web today use the Common Gateway Interface, or CGI, to create and deliver their dynamic web content. CGI is a generic interface for calling external programs to crunch numbers, query databases, generate customized graphics, or perform any other task on the web server. CGI programs can be written in any programming language, but Perl is by far the most popular language to use with CGI. Initially developed over a decade ago for text processing, Perl has evolved into a powerful object-oriented language that has become a favorite of web developers. CGI programmers appreciate Perl's text manipulation features and the CGI*pm module, which provides a well-integrated, object-oriented interface for almost all CGI-related tasks.
