Global.asa: To be or not to be?

To educate all coders when or when not to use the 'Global.asa' file and the conditions you must fullfill when you do use it. I knew I had a lot of trouble finding documentation like this. If you like it, please feel free to vote for it. Let me know what I can do to improve myself too, cuz this is my very first tutorial that I wrote. I've been told I'm good at explaining, but let me know ok? :) I'll see if I can dig up any more info on the 'Global.asa' file and try to continue this lesson. The most important reason why I created this tutorial is because most advanced scripts(i.e like my chat script, some database scripts, etc) use it. Very important piece of knowledge to be able to have at your fingertips. Now you can even impress your date with this stuff! ^_^ Not!! Hehe.

doing?

user leaves the site. With the session object you can track users and their
events and much more.
