Logging out of the Facebook iFrame IE Application

I have a problem with my Facebook application when a user uses Internet Explorer. My application loads into iFrame as a canvas.

Cookies and Session are lost after sending. This does not happen at all in Firefox, and it does not happen in IE if I open the application outside of Facebook, that is, using a direct URL.

My app is an Asp.net C # app, but that doesn't really matter.

I think the problem is bigger than the Facebook problem ... any website loaded in iFrame using cookies / session, IE prevents cookies / session from being saved, but is there a way Facebook can overcome this? I have to use sessions in my application, not just for re-checking repeatedly and again, but for other things.

Please help me. Thanks!

Most likely, you need to implement P3P headers in your application, for more information see the following: http://forum.developers.facebook.net/viewtopic.php?id=452
