Ah I see.  The CA could reject OCSP requests for a certificate if they were
a jerk (or the customer didn't pay).  But the server's OCSP request looks
the same as a browser client OCSP request absent any non-standard
fingerprinting.  The CA's server can't reject all OCSP requests, because
the (web) server needs to make the requests.
