Session in tab browsers

Hi friends

i have an application in which when i log in -- according to the role of user im setting some beans in Session with a fixed key name eg "key1". Because as i know every browser window will have different session so no conflict will come. But i got problem in tabbed browsing. It happens so that all tabs opened in a window share same session. so if two usersof different roles are logging into my app through different tabs but same window. Then problem comes. So could any one who encountered same prob and have a solution, help me.

Thanks in advance :-).
