How to login with different user in same browser?

The link provided by you is can be an option, but i have to do changes everywhere in the code if i generate the new page id and store it in viewstate etc. And my question is very clear, i want to login different user in same browser(same browser different tab), how can i do that in asp.net?

I don't think so, might be i was wrong but there is only one application state through out the application but we can have multiple session state, other wise multiple user can't be login at same time whether they are logged in with different browser, and my question is different i want to make login of different user at same browser on different tabs. Now the problem is session stored in the cookies, so even we open the different tabs in the browser the cookies will remain the same, so whenever i will open the new tab it will automatically make me logged in. So i am looking for this problem solution.
