OCSP doesn't work when the user is going through an authenticating HTTP proxy. Either we will silently ignore the OCSP failure (default behavior), or almost every HTTPS site will stop working for said user.

Do you have arguments why to back this out rather then fix the actual bug 701019? I still miss it and therefor I'm strongly against.

1. We should do this as ridealone to any 8.0.2 release. I don't think we should land anything more complicated than the backout for 8.0.2. 2. Similarly, I don't think we should land a fix for 701019 on mozilla-beta, but we should fix the regression for mozilla-beta. 3. More generally, it isn't clear that we can just change what LOAD_ANONYMOUS means yet, I don't have time to think about that right now, but we should fix the regression ASAP on mozilla-central and mozilla-aurora.

The whole motiviation for the addition of the SSL thread had been done in order to support OCSP trough proxies, and the last time I had tested that used to work. Why do you think it doesn't work? Have you tested it? In particular, which is the oldest version where this regressed?

Thanks Brian. Now I understand. I had to take a look at the target milestone of bug 662996 first. I agree now. I'll have a patch for this soon.

Commenting out the code added in bug 662996. Kai, the regression we are trying to quickly fix here is that an OCSP request cannot go with the LOAD_ANONYMOUS flag set through a proxy requiring authentication. It causes blue larry for EV certs. This regressed in Firefox 8 for which bug 662996 has landed. This will be fully fixed in bug 701019 because there are also other issues caused by incorrect behavior of LOAD_ANONYMOUS flag (as I see it). That fix needs a security review first and is expected to be too risky for Aurora, Beta, Release.

Comment on attachment 574972 [details] [diff] [review] v1 [Triage Comment] For anybody just joining us, this is basically a full backout of bug 662996 (albeit by commenting out the change). Approving for Aurora/Beta, pending landing on m-c first. Please land this ASAP to make it into today's build.

Setting resolution to Verified Fixed on Beta.

I have tried this using the link from the description and the secure notification is present (green site's identity button). I get no error with the pref activated: "When an OCSP server connection fails, treat the certificate as invalid".

Marking as fixed for Firefox 11 since this landed while 11 was on m-c.
