i'd be careful using CGI, this module is a real good hack, but BIG (using 3,5 mb of your memory when compiled).

It's worth pointing out that whilst it's true that CGI.pm contains a lot code, it also implements a pretty ingenious code loader that it only actually compiles the code that you use. So you shouldn't really worry about loading code that you aren't going to use - CGI.pm is actually pretty efficient.
