Maintain Multi Session on Multiple Tabs of browser

How do you maintain multiple sessions on different tabs of browser.

Yes this is an interesting topic.

I knew it was easy if we were using cookieless session, but ours is a cookie enabled session.

I was struggling all the day and then I finally got a hint that we can use Web.config to handle above issue.

Wondering how?

 <sessionState cookieless="UseUri" regenerateExpiredSessionId="true">
  </sessionState>
