When we block subdomain requests we need to notify IE that the request is going to be blocked. Currently there were 3 tries of that:

If we just report the request a failed IE will display the ""Internet Explorer cannot display this page" in place of a source iframe
If we report that the request is "redirecting", some events will not fire on the DOM, and bugs like #1193 appear.
If we just report that the request is ok, IE would still make the request, though result might not be shown.

We need to figure out a correct way of blocking these requests.
