How do I detect when user logs off

[aplusc]

I have a secure application with a "log off" button. It redirects users to another page (i.e. "you are logged out&quot. This is how I detect when the people log off/log in and store it in a log .txt file.

Unfortunatelly very few people actually use the "log off" button. They probably just close their browser. How can I detect when they do that?

Preferably, is it possible to do this WITHOUT editing the global.asp file?

Thanks for your help.

Opps, I mean the "global.asa" file

<%
If IsClientConnect <> True then
'The user is not connected
'Do whatever
Else
'Client is connected
'Do whatever
End if
%>

Thanks .. that might work, but how can the user execute that code if he is not connected any longer?
