how do i detect when a session ends?

[John Blair]

Hi,

I would like to be able to detect when a session ends in a page_load event
in asp.net - is this possible?
Thanks.

You can't.

Thanks but you can.

either test session("var") is nothing or use
Session.IsNewSession

Thanks.

Wrong.

That only detects whether a session is a new session,
not whether an old session has timed out.

Off topic but I couldn't contact you otherwise Juan. Do you know more about
this issue now ? :

I still owe you, Tom.

This is a pesky issue.
We've had a couple of exchanges, but nothing definitive yet.

As soon as we have something definite, I'll post it.

Thanks.

I'll second that.

On the server side, whenever you process a request, there is a session
associated (if it is a new one, IsNewSession is true).

Even if you call Session.Abandon() in your page_load, in your
page_prerender, the session is still valid for _this_ request (not for
the next one -> will be within a new session).

Hence the only way to determine that some call has abandoned the
session within a request is to set some flag in session or request
state (e.g. Session["AboutToEnd"]=true) and then check for this flag
when rendering your output (.Visible=(Session["AboutToEnd"]==null))

Remember, this is server side - clientside is a whole different story
where you can tackle the session timeout beast e.g. with javascript
