Session State Between Projects
could use a bit more on your deployment scenario. Are both sites hosted on the same machine? do they hit the same database? Are you just trying to store one variable - can you put it into a cookie? Do the users log in - are the login credentials checked againsts the same DB?
I believe the default session state is bounded by the ASP application. However, if you use session state in a database, then it is possible to share it across machines.
