The Common Gateway Interface (CGI) is one of the most powerful methods of providing dynamic content on the Web. CGI is a generic interface for calling external programs to crunch numbers, query databases, generate customized graphics, or perform any other server-side task. Based on the best-selling CGI Programming on the World Wide Web, this edition has been completely rewritten to demonstrate current techniques available with the CGI.pm module and the latest versions of Perl. Topics include incorporating JavaScript for form validation, controlling browser caching, making CGI scripts secure in Perl, working with databases, creating simple search engines, maintaining state between multiple sessions, generating graphics dynamically, and improving performance of CGI scripts.
