trapping asp.net session end

Hi,

I would like to know if there was a way to trap a session timeout on
an asp.net event. What I mean is that I've set a session timeout in
the web.config file. What I would like to do is when that timeout is
reached, I would like it to fire an event. Is there some event in the
global asax that could fire when the session normally ends. I need to
capture this to call a corresponding function during time lapse
timeout.

:D

For InProc Session, the Session_End event in global.asax *is* the event that
is fired when a user Session has expired.

Session_End will fire when an inproc session terminates.

N.B. closing the browser or navigating to a different website will *NOT*
cause the session on the webserver to terminate...

or....if you have a session variable, let's call it "SessionTestVar",
then, you can do something like this:

<script language=3D"javascript" type=3D"text/javascript">
function ShowTimeoutWarning ()
{
window.alert( "Oh-ho!Session Expiring!" );
window.location.href =3D "your_start_page.aspx";
}
<%
if
( HttpContext.Current.Session["SessionTestVar"].ToString()!=3Dnull )
{

Response.Write( "setTimeout('ShowTimeoutWarning();', " +
( Session.Timeout *
60000 ).ToString() + " );" );
}
else
{
Response.Redirect("your_start_page.aspx", true);
}
%>
