Session State

we've just set up a subdomain,'demos' for one of our projects that normally works fine. on the login page, if the user enters the correct username/pw, we write session info and then response.redirect to the home page. this works for on the normal site, but session state info is dying on the demo subdomain.

i'm sure the session info is being written since i can see it when i response.write the value. also, the response.redirect uses a relative path, so it's not that we're accidentally changing domains.
