Section C.9. The CGI.pm Module

C.9. The CGI.pm Module

C.9.1. Introduction

The most popular Perl 5 library for writing dynamic CGI programs such as guestbooks, page counters, feedback forms, etc., is the CGI.pm module written by Lincoln Stein; it is included in the standard Perl library starting with version 5.004. The most recent version of CGI.pm can be found at www.perl.com/CPAN. CGI.pm not only takes advantage of the object-oriented features that were introduced in Perl 5, it also provides methods (GET and POST) to interpret query strings, handle forms, and hide the details of HTML syntax.

Lincoln Stein has also written Official Guide to Programming with CGI.pm[6] (www.wiley.com/compbooks/stein), an excellent, easy-to-read guide from which much of the following information was gleaned.
