问题
I have a facebook app built using iframe. It works ok on most modern browsers except Safari on Windows platform. On Safari windows platform, the cookies seem to get lost as a user move from initial form page to 2nd page with questions.

besides header, you might also need to add w3c/p3p.xml and w3c/policy.p3p files to your website. See here for more details and sample files: Session null in IFrame in ASP.net MVC only in safari browser
