When I open two browsers(both instance of browser run the same application) on my computer and log in first as one person and then log into the second one as a different person. The first browser becomes the second user also.
Normally web applications dont behave this way, can u please suggest me whats going wrong and possibly some solution for it.

Somu.

*Most* web applications work this way. When you open a new window using Ctrl+N or File | New Window, both browser windows will share the same cookie collection (and other settings).

Since authentication is often done with cookies, both browser windows will submit the same cookie's so effectively you become the other user in the other browser window.

To avoid this, start a new instance of a browser, instead of opening a new window from the current one.

Thanks Imar
Is there anyway to solve the above problem ???

Probably not.

This is the way the Web was built. A connection between a browser and a Web server is stateless. This means that as soon has you have been served the page you requested the Web server forgets about you. To enable a Web site to track those "anonymous" users / connections, cookies can be used. Whenever you request a page, the browser also submits the cookie collection that falls within the scope of your request. So, both browser windows will submit the same cookies, making it appear they are the same user from (quite possibly) the same browser window. The fact that your end user is actually using two windows is not visible to the Web server.

Maybe this can be done with client side JavaScript, but I am not even sure how to do it, or wether it's possible at all.

Why is this so important to you?

While typing this post, I was listening to: Falling Away With You by Muse (Track 6 from the album: Absolution) What's This?

Keep in mind also that you will never be able to control how the user opens a new window except when you are using client side script. And in that case, the browser will be opened as a sibling/child window and will most likely share cookies. Different browsers will handle this differently however.
