I am constructing an app that collects data from different domains via JSONP. These sites are secured via OpenId. Once I have previously logged in to those sites and my client has the OpenId cookie, both Firefox and Chrome will see me as authenticated and send me my data.
IE 9, however does not see me as authenticated and sends the login page back instead of the data.
Is there anything I can do, any special mode of IE I can use, to allow IE to pass back that token with the JSONP request?
