Our web application is protected by cookie provider that will do redirect every 60 seconds to check user's credential. I am using dojo.io.bind and FloatingPane. When it hit that 60 seconds, when the browser is requesting one page from the web server, web server will redirect request to cookie provider. When I use fiddler2 to track the browser traffic. In IE 7, it will stop there with a 302 on the page requested and 200 on the cookie provider url. It didn't receive the redirected page back. In IE 6, it's working fine. The browser will get the redirected page back.
