Not sure I understand you correctly ... Are you trying to say that "Zen load balancer" can dispatch the requests to a different backend after a 40x/50x response? No, haproxy doesn't support that and I don't see how this would make sense. 40x are client errors, redispatching it to another server doesn't even remotely make sense. 50x errors may be a result of overloaded backends or database failure. Dispatching it to a different backend will result in even more load and infinite loops (if the database behind the backend is down for example). I strongly suggest fixing the real problem, instead of implementing such dangerous workarounds at proxy level. Regards, Lukas
