IE 7 Tab Issue

I have a web application. Server - weblogic 8.1 using JPF (Java page flow)

Lot of may object are in session and in JPF as JPF has a session scope.

When user open a new tab in the same instance of IE7 or mozilla ,there is no new session, they are continuing same session.

My problem is , when user open a new tab and and again login with same name or different name login, all the objects in my session and in my JPF gets over written with new one.

So first user unable to navigate through pages.

What is solution

If new tab open , I want a new session started.or how can i preserve session object
