Develop right CGI scripts

I came across Ovid’s CGI Course. It’s definitely good tutorial. Both experts and beginners will find there something interesting and helpful. I found the third part – Basic Security the most important and interesting for me. I’d like to add that you can find many useful extensions for CGI like CGI::Forms, for example. This module will do all routine work for you to produce web forms. Or here is a CGI::Framework – a simple-to-use, lightweight web CGI framework.
But notice that using plain CGI is defensible in case of simple web script. If you’re going to develop something serious have a look some Perl framework such Catalyst, Gantry or Maypole. They’re enough powerful to be a base of scalable and efficient web applications.
