facebook iframe app; php sdk getUser() returns valid id on page one but not for any other page


I have a facebook iframe app which correctly logs in and authorizes the app, but getUser() only works on the first page. As soon as a user clicks a link to a new page within the iframe, getUser() returns 0.
