Session_OnEnd?????

When does the Session_OnEnd event in the Global.asa file execute?

If I put the following in my Session_OnStart

Response.write "Started"
Response.end
it works fine, so I can see that my Global.asa is executed

In my Session_OnEnd event I have

Response.write "Ended"
Response.end

I have a link on my site that calls the session.abandon event, but when clicked the session_OnEnd does not happen

What happens when a session.timeout occurs, is the session_Onend supposed to execute?

What happens when a user closes the browser, is the session_Onend supposed to execute?
Basically I can Never see that my session_OnEnd is executed

PLEASE HELP, I am desperate?

The session ends when you call Session.Abandon or after the Session times out (normally 20 minutes after the user requested the last of your pages he's looking at, but the time can be changed.)

I didn't think you could use Response.Write in the global.asa. Even so, supposed the user closes their browser and shuts their computer off. The session ends twenty minutes later. Where's the Response.Write going to go?
