英语翻译 10.5.4 503 Service Unavailable The server is currently unable to handle the request due to a temporary overloading or maintenance of the server.The implication is that this is a temporary condition which will be alleviated after some delay.If known,the length of the delay may be indicated in a Retry-After header.If no Retry-After is given,the client SHOULD handle the response as it would for a 500 response.Note:The existence of the 503 status code does not imply that a server must use it when becoming overloaded.Some servers may wish to simply refuse the connection.
