Guiding readers to get the most out of the power and versatility of using Perl and Common Gateway Interface (CGI) together to solve common problems faced by Web-based applications, the authors explain techniques covering a wide range of concepts, and show the reader how to write almost any Perl/CGI application. A companion Web site has codes for examples in the book, and links to other resources.

Writing CGI Applications with Perl offers the most practical examples of applying Web programming techniques to real world problems I've seen yet. The text blends good CGI programming techniques, idiomatic Perl, and databases into many large and useful examples. Careful attention is paid to demonstrating solid, scalable code for production use. This is not your typical 'Hello, World' CGI programming book.
--Clinton Pierce, Perl trainer and author of Teach Yourself Perl in 24 Hours

With its sophisticated database, network, and multi-platform capabilities, the Perl programming language has emerged as an ideal tool for developing CGI-based Web applications.

Writing CGI Applications with Perl shows you how to use Perl to accomplish the most vital tasks needed for today's online applications. Using numerous examples, line-by-line code explanations, and skill-stretching exercises, this book not only provides useful cut-and-paste code for your own programs, but it also teaches you practical skills and techniques that will enable you to develop any kind of CGI-based Web application with Perl.

Focusing on the most important areas of Web application development, including database interaction, form and file handling, security, e-mail, and graphics, the book provides in-depth coverage of such specific topics as:

• Working with HTML Web forms and obtaining user input
• Cookies, tracking clicks, and access counters
• Using the mod_perl Apache module
• Connecting to a POP3 server for e-mail
• Perl DBI and databases on the Web
• Tying a hash to a database
• Embedding Perl in HTML with HTML:: Mason
• Remote file management via the Web
• Creating dynamic images
• XML and its derivatives, RSS and RDF

In addition, introductory material is 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.

Geared toward the needs of today's professional Web developers, Writing CGI Applications with Perl provides the specific tools, experienced-based techniques, and overall concepts necessary for quality Web application development.
