Description:

Sams Teach Yourself CGI in 24 Hours teaches the next step beyond simple HTML Web pages. This new edition covers implementing CGI with both C and Perl, and discusses CGI's relative strengths and weaknesses in comparison with other Web programming technologies like JavaScript, Java, and PHP. The book takes readers from the basics of CGI--learning, for example, how to implement and customize existing CGI programs--to the point where they can use CGI to create their own programs from scratch.
