Thanks for your answers.
Now I understand I have to use setTimeout to achieve my goal.
The link http://www.crowes.f9.co.uk/Javascript/timer.htm is really helpful.
Which client side event I should use to keep track the user is still using
the website.
Thanks,
Benjamin

All you need is one client side event to fire once the trigger time has
elapsed and you want to warn the user.
You can name the event anything you want.

The event would be the TimeOut Interval triggering the function that
setTimeOut refers to.

Please post back here if (and when) you find the culprit.
I have stopped using sesion variables altogether becuase of
similar issues on a client's server, but am very interested
in what you figure out.
Now my client may well be changing the web.config file
which will cause the application to restart, all the more
reason to not use session varialbes (in my case).
Instead I pass info encrypted in the query string, which
works just fine, the only session variable I use is to
relay error messages to tan error page - if that gets
lost, oh well.
kpg
kpg,
what I figured out was the app was getting recycled due to a limit I had set
on virtual memory. There are times when the virtual memory usage jumps up
dramatically and then it pops right back down. The app does not appear to be
leaking memory at this time. So, I unchecked that option in the App pool's
configuration.
I used information garnered from this link to aid me in my quest, although I
haven't completely implemented Peter's Exception Engine.
http://www.eggheadcafe.com/articles/20030816.asp
I placed this code in my Application_Error routine in my Global.asax file:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs when an unhandled error occurs
' check to see if the ASPNETApplication log exists
Dim b As Boolean
Try
b =
Convert.ToBoolean(ConfigurationManager.AppSettings("logAppErrors"))
Catch ex As Exception
End Try
If Not b Then Exit Sub
If Not System.Diagnostics.EventLog. _
SourceExists("AnnexationTrackerApplication") Then
System.Diagnostics.EventLog. _
CreateEventSource("AnnexationTrackerApplication",
"Application")
End If
System.Diagnostics.EventLog. _
WriteEntry("AnnexationTrackerApplication",
Server.GetLastError().GetBaseException().Message)
End Sub
The message appeared in the system event log not the application event log.

Session VAriables
If I declare a session variable: session("Link") and
later code: session("Link") = Nothing, will that free up
the space taken up by the variable? Or do you have to
abanden the session?
ThanksSession.Remove("Link")

You can use the Session.Contents.Remove method to delete a single value.
The following MSDN link has more details:

hi,
there is also SEssion.Clear()
will clear the values of that keyname.
Session.abandon is the best bet... though
