Is there a support to match headers?

[stribny]

I'd like to be able to provide set of required headers to register_uri so that the URL is mocked only when the headers match. Is this possible?

This would be handy for us too, as we're trying to use HTTPretty to test a SOAP API, where there's only a single IP and different "endpoints" are determined by a SOAPAction header only
