"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Please help!
Did a search in Google for "user application global.asa" and found this document:


If a user doesn't explicity log off, the only way to tell the user is inactive is if the ASP session times out.  If you wanted to track individual users, you could create another Application variable as an array that contains the user names and other info.

here you go
