Mirror NSS's GET-vs-POST selection criteria, wherein GET is preferred
over POST (as the former might be a response from a cached CDN entry,
whereas the latter might hit a live responder). However, only accept it
if it definitively says "Good" or "Revoked" -- trigger a POST request
when an unknown or failure status is seen.
