There two errors which can be returned by proxy module in case of upstream problems: 502 (if an error occurs) and 504 (if a request times out). Usually it's good idea to handle both of them. The 503 code is never used by proxy, it's only returned by limit_conn / limit_req. -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
