Session.Abandon() does not abandon the session straight away

In my ASP.NET web app I call Session.Abandon() in Page_Load(). I would expect this would abandon the session straight away and the next time I reference the HttpContext.Current.Session a new session should be created. However, putting breakpoints on the Session_End and Session_Start handlers in Global.asax indicates that these aren't called until the page has finished rendering.

So two questions:

1) Why?

2) How can I continue to use HttpContext.Current.Session within a page lifecycle once Session.Abandon() has been called.

Thanks in advance!

    Look at the remarks section on the linked page. Looks like the session objects are only queued for deletion, and not deleted until the code finishes running.
