POST-Once-Exactly

↖All extensions

The POST method is neither safe nor idempotent. This poses a problem to the client: if an HTTP-request from the client is not answered by a (correct) HTTP-response from the server, the client has no way to determine if the request processed successfully or not. To circumvent this limitation, server implementations are encouraged to implement POST-Once-Exactly POE.
