Session in Iframe working in Firefox but not in Internet Explorer

Im trying to get a form working in Internet Explorer. I see that when i submit this form in Firefox I can start a session and send my webbrowser to the right page based on that Session. In Internet Explorer however when i'm debugging the $_SESSION i retrieve an empty array back, this means that in Internet Explorer the session isn't started on my 开发者_如何学Csecond page.

This is the code i'm using to print the session on my second page:

session_start();
 //unset($_SESSION['bp_email']);
 include("includes/_dbconnect.php");
 print_r($_SESSION);
 die();
