There shouldn't be a problem with retrieving the response in IE 8. Such response works in my tests (direct from Fiddler raw view):
HTTP/1.1 200 OK
Content-Type: text/plain; charset=utf-8

Perhaps logging the request will give us some insight on the problem.
Using a second request is a valid option, but we shouldn't need it.
