it won't work. Haproxy tries to redispatch as far as it can. If you see a 502, that means that the request was *really* forwarded and that it does not have it anymore. So it won't be able to redispatch it to anyone else. That's one reason some people like to put caches such as nginx or varnish before or after haproxy. Caches by their nature are able to replay a request if they consider it is not risky, because they keep a copy of it. Regards, Willy
