The World Wide Web is more than a place to put up clever documents and pretty pictures. Using the Common Gateway Interface (CGI), you can offer interactive queries and serve instant information from databases, worked up into colorful graphics. This book offers a comprehensive explanation of CGI and related techniques for people who hold on to the dream of providing their own information servers on the Web. The author starts at the beginning, explaining the value of CGI and how it works, then moves swiftly into the subtle details of programming. The majority of examples use the most common platform (UNIX) and the most popular language (Perl) used for CGI programming today. However, the book also introduces the essentials of making CGI work with other platforms and languages.
