Session.abandon and Session.Cleear: what is the difference

[JJ_377]

What is the difference between Session.Abandon and Session.Clear?
Thank you.

 

[Juan T. Llibre]

Session.Clear stays in the same session.
Session.Abandon dumps the current session and starts a new session.

Session.Abandon() will end current session
Session_End will be fired and next request will fire Session_Start

Session.Clear will just clear the session data , the session is still alive

Session ID will remain same in both cases, as long as the browser is not
closed.

Thank you - my further question,s what is recommended in terms of
clearing any session variables in the context of:
1. on error, I want any session variables cleared and the user
redirected to a logon page
( I wish to prevent a user from reentering the error page and
recreating the original error)
3. I wish to prevent others from "backing" into web pages if a user
does not log out and session timeout has not yet occurred.

I have the web pages set so that the browser will not cache them

It kind of sounds like I just need Session.clear, but I have been using
Session.Abandon.

MY thanks!

code for proper logout

on signout button click

Session.Abondon();
Response.Cookies.Clear();
FormsAuthentication.SignOut();
Response.Redirect("../product1.aspx");

on Page_Load()

Response.Cache.SetNoStore();

this can solve back button problem
