Scott Beardsley commented on TS-3362:
-------------------------------------
Fei, it looks like you are re-using existing metrics. Would it make sense to
report these error conditions into new metrics instead of overloading the
existing user_agent_unknown_cert and user_agent_revoked_cert? These metric
names don't provide any hints that they may be related to OCSP.
Also, you had a different version which reported debug messages to the
"ssl_ocsp" tag instead of just "ssl". I found that useful for debugging just
ocsp related issues.

> When get OCSP response, we check it before cache/staple it. If it's negative,
> I think we'd better discard it instead of sending back to user agent. This
> would not increase security risk: User agent would query CA for OCSP response
> if ATS does not staple it with certificate.
