Multiple Webbrowser, Force New Sessionid?



I have a vb.net that has one form with multiple webbrowser controls.
If I log each webbrowser into the same site, they all have the same
sessionID.

I need each webbrowser to log into the same site but with a different
SessionID. Can this be done? From what I've seen, SessionID goes by
the Process which, in my case are all the same.

help!
