IE8 session/cookie problem - SOLVED

[eluser]Vitthal[/eluser]
Hi Simon,
i am having one problem related to IE 8 session.
I am using IE 8 for my web but it randomly shows me an error 'Session expired' and diverts me to the session expired page of my project , while i have kept session timeuot=500 in my web.config file. It works really very fine on IE 7.

Currently i am using WIN XP SP2 , .Net Framework 2.0 , IIS V5.1 ,AJAX.

The problem really stuck my work since last one n half month n still i dont have a solution.
DO u have any idea please help me.

Thanks in advance.
