Hi, I'm contacting the list after doing some Google-foo and not finding anything - not sure if this is due to my searching skills, or because nobody ever asked about this... pardon me if it's a known issue, and a link to a relevant resource would be appreciated in such a case.
I'm using Nginx as a reverse HTTP proxy to Tomcat, primarily for the purpose of doing OCSP stapling. When Nginx starts for the first time, and there's no cached OCSP response, the first client to try an OCSP will fail; I understand that this is by design, and I've overcome it by simply 'warming' the cached manually by using OpenSSL's s_client... of course I'll be happy to learn there's a way to make Nginx block and get OCSP response if there's a cache miss (I understand that blocking every time in case of OCSP server being down won't help performance much, but I guess cache can be negative in such a case, instead of a miss, and maybe this is already the case...) Anyways, that's not the main issue I have. The main issue I have is that when a revoked certificate is being used by Nginx, and an OCSP is being conducted against the server port where this certificate is served. Watching the packets arriving from ocsp.digicert.com via Wireshark, I see the OCSP response saying that the certificate is revoked (so, Nginx seems to be querying the OCSP server fine?), and I also see this in Nginx's error log: 2014/04/07 17:44:41 [error] 27005#0: certificate status "revoked" in the OCSP response while requesting certificate status, responder: ocsp.digicert.com Yet, the OpenSSL s_client, even after multiple attempts (so the cache should be "warm"), returns that no OCSP response was returned from the server... Naturally, I would expect the response to be proxied by Nginx back to the client. What am I missing / doing wrong? :) Thanks a lot! -- Shimi
