If there is a way to filter to the exact match instead of startswith, we might
be better off.

In general, POSTs won't be handled which could be forms and not XHR maybe (I
don't know), but at the same time, all this has to test is that the main
resource is tested, hence the exact match.

I think it will be more robust if we only test one resource if we are using a
webpage that can change unexpectedly.
