Feifei Cai commented on TS-3362:
--------------------------------
Oh, yes, you're right. The fetch and check of OCSP response is an independent
thread, not in ssl handshake. I should report it in some new metrics, e.g.
proxy.process.ssl.ocsp_revoked_certstatus,
proxy.process.ssl.ocsp_unknown_certstatus...
And, I'll extend ssl debug tag to ssl_ocsp. Will attach a new patch as soon.
> Do not staple negative OCSP response

> 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.
