Weird Safari Stalling Issues Sessions?

Dear All, I'm having a very frustrating issue w/ Apples Safari web browser. The browser will stall when I try and initiate a sessions on login . So on our login page we validate the username and password and start the session. When a Safari user attempts to login the Safari wheel just spins and spins. I've restarted the browser, cleared the cache , cookies and history to no avail. Putting in a bad username password causes no lockup and the proper "bad auth" page is shown. I've added: // attempt to fix Safari issue header ('Expires: 0'); header ('Pragma: no-cache'); to the header and still no luck. I've found many similar incidents on the WWW with no real solutions. Has anyone had similar issues and found a workaround for this problem? I believe this is a Safari issue and not a PHP problem. But I'm hoping someone has created a solution w/ PHP.
