Hi,
Yesterday I was discussion with my colleagues about session and a few
interesting things popped up. So I thought I would share the same with
all.

No, they don't. Session.Clear removes the session variables, but
Session.Abandon doesn't remove anything at all from the session, it only
flags the session object to be abandoned after the request has been handled.

Yes, of course. Abandoning the session will end it, and the next request
will start a new session. Clearing the session variables doesn't end the
session.

Session Class has two methods. Session.Abondon() and Session.Clear().

Firstly, it's Abandon, not Abondon...

Secondly, the Session object has eight methods, not two:

And thirdly (as Göran has pointed out), your distinction between the
Abandon() and Clear() methods is incorrect...

I suggest you remove the blog entry...
