How can i allow multiple tab browser sessions? I've done research and found this line of code:
<sessionState mode="InProc" cookieless="UseUri" />
I was not allowed to use this because the url was displaying the session id on every tab. Are there any other way else i can allow unique session id in multiple tabs? Does any other state managements available is able to work in multiple tabs?
You can't. Whatever session method you're using, it will still be possible to get the same session into multiple tabs, and impossible to detect on the serverside that a page has been opened in a new tab.
Regardless of whether you're allowed to use it or not, the UseUri session management method won't help. If a user tries to open a link in a new tab rather than in the current window, you [a] have no way of detecting this on the server-side, and [b] you have no way on the server-side to create a new session, transfer the page execution to this new session, all whilst keeping the current session intact.
