As of now, keepalive connection retries aren't aware of idempotence, much like proxy_next_upstream. Retries are only done in case of early errors though, and this is expected to be good enought in most cases. The future plan is to teach proxy_next_upstream and friends about idempotent or not idempotent methods, and probably also splitting "error" state into errors before we were theoretically able to send at least some bytes of the request (that is, retries are for sure safe even in case of non-idempotent methods), and errors after that point. -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx-devel
