Problem with maintaining Sessions with some Facebook users

Jan 4, 2008 at 12:27 AM
I build this IFRAME app (http://apps.facebook.com/moralpolitics/) which works well for abut 50% of facebook users. For the other 50%, I can't seem to be able to maintain a session state. I can reproduce the problem if I disable cookies for the app web site. Somehow I find it difficult to believe so many users disable cookies and I wonder if there is another cause.

Also the alternatives are limited. I have been unable to get the Facebook redirect authentication to work when using cookieless session on the ASP.NET app side.
Any thoughts?
