Hello, I'm comparing Squid 2.7 to Squid 3.1, and I've found the error code returned between the two versions differs when attempting to fetch a site where the domain name does not exist. In Squid 2.7, it returns an HTTP 504 (Gateway Timeout), while Squid 3.1 returns an HTTP 503 (Service Unavailable) I've narrowed this down to FwdState::makeConnectingError(err_type), but I'm not sure if this is by design. It seems to be related to whether the request requires validation, but I can't see an obvious way to force this via configuration. In lieu of finding a way to force Squid 3.1 to always return an HTTP 504 error code, I've prepared a patch which seems to work, but I'd still like some community feedback prior to submitting it. Is there a particular reason why Squid 3.1 will return either HTTP 503 or 504, depending on whether the request requires validation?
