I agree with the point that the domain name may not map nicely to what's
prohibited, but it's probably not necessary to consider other domain
names covered by the certificate.

SNI (https://tools.ietf.org/html/rfc6066#section-3) is more or less
universally used by today's browsers, so the domain name associated with
the request is in cleartext (at least for the first request in an HTTPS
Keep-Alive session).

Regards,
Andrew McNaughton
