I don't have a direct answer on your observed problem, but I would point out that judging by my archives, the use of the http_proxy option is /extremely/ underrepresented on this list. I have no information if this might be the case, but I suggest that it would be possible for a bug to creep in and remain hidden for longer in this code path because of its relative rareness. This mean-time-to-bug-discovery might be compounded by the very (very!) broad demographic generalisation that people using this simplistic feature of haproxy /might/ be less inclined to upgrade for feature-based reasons, due to their architectures perhaps relying less on a fully-featured proxy being inline. In the absence of any other information, my next steps in your situation would be to see if I could replicate this problem in a different haproxy mode, not using option http_proxy. I absolutely recognise that that might not be possible, and I'm sure others on the list will help you discover the true root cause of the problem. I only mention it as it might not be obvious that this isn't a commonly discussed, hence maybe used, feature of haproxy. HTH, Jonathan
