Description

Writing CGI Applications with Perl shows how to use Perl to accomplish the most vital tasks needed for today's online applications. The student benefits from the numerous examples, line-by-line code explanations, and skill-stretching exercises. This book not only provides useful cut-and-paste code for programs, but it also teaches practical skills and techniques that will enable the development of any kind of CGI-based Web application with Perl. There is introductory material provided for newcomers to CGI or Perl. Numerous appendices include handy references as well as a guide to Perl documentation. A companion Web site, http://www.perlcgi-book.com, contains the code for all the examples.
