Does anyone have any suggestion how to record the amount of time a user spends on a site from when they login to when they logout.

I can make it record the time they login and the time they logout, however what happens if they don't log out or their browser crashes. How do I get it to record the logout time less the session timeout amount (probably 30 min). Would it need to be some sort of script on the server to do that ?

In your global.asa file keep track of session start time and end time

*********************
Global.asa
**********************
sub Session_OnStart
' Your Session Start Time
end


subsub Session_OnEnd
'Your Session End time
end sub
