Recently I was developing a Facebook iframe application using PHP and all was good until I got few complaints that the application wasn’t functioning as it’s supposed to on IE8. I was using the Facebook php-sdk and I have tested this app successfully on Firefox 4 and Google Chrome 11. Since I was on a Ubuntu box, I tested the app on IE6 under wine and I didn’t have any issues as such. I had to get a help from a friend using Windows and IE8 to dig deep into the problem. The issue seemed that session data didn’t persist across the application specifically on IE8.
<?php header('P3P: CP="CAO PSA OUR"'); ?>
That’s it. All problems automagically solved..
