ASP.NET session id shared amongst browser tabs

Question

I\'ve recently been developing a website using asp.net webforms that uses in proc sessions and I noticed that session ids are shared amongst browser tabs. So I was wondering

Answer 1

Some have suggested adding uniquifiers into the URL, and tracking based on those.

If you're going to do this, you may as well just let ASP.Net do this for you by turning on cookieless sessions - it then uses the URL to contain the session ID.
