No. Quoting CHANGES (http://nginx.org/en/CHANGES): *) Change: non-idempotent requests (POST, LOCK, PATCH) are no longer passed to the next server by default if a request has been sent to a backend; the "non_idempotent" parameter of the "proxy_next_upstream" directive explicitly allows retrying such requests. Connect errors doesn't imply that a request has been sent to a backend. As long a request hasn't been sent yet, it can be retried to another server without any problems.
