Hi, We are running into an issue that has come up a few times on the mailing lists - host header forgery detection when using SSL peek in order to include SNI logging in access logs. (Clients operating in transparent mode).
As far as I can tell I have narrowed it down to ClientRequestContext::hostHeaderVerifyFailed, there is a line - if (!Config.onoff.hostStrictVerify && http->request->method != Http::METHOD_CONNECT) Along with the comment "// NP: we do not yet handle CONNECT tunnels well, so ignore for them". If I remove the method check then the sites hitting this issue start loading fine, however, I don't know what the implications are of doing this - especially given the comment. (I do understand the implications of disabling host verification entirely). It's also worth noting that this still occurs even when both client and server are using the same DNS servers (although it's not as often) and clearly it is a problem that does occur in the real world. What is the impact of removing the method check so that this code path is used for CONNECT requests?
