I recently began studying CGI for CIS513 presentation. I realized then that CGI is an inescapable part of any cool and interactive web site. You want a message forum for your site? How about a feedback form, or a counter? As I found out, the only way to make these things happen is through CGI scripts. Make no mistake, CGI is not the only language when it comes to making your site cool and interactive, but it's definitely the most important and one the web can't live without. So we should have a much better understanding of what CGI is in general, and also to know how to install your CGI scripts.
