<div>According to <a href="http://tools.ietf.org/html/rfc2616#section-6.1.1" target="_blank">http://tools.ietf.org/html/rfc2616#section-6.1.1</a> - the reason phrase is meant for human consumption and you're allowed to say whatever you'd like here. The reason phrase is required by the RFC and the question is whether Varnish should require it or not. After all, it isn't used for anything so I don't see a reason why we should require it. Then again, we cannot be faulted for declaring a backend sick when it is in violation of the protocol.</div>
