minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] but not http 404 all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

Join them; it only takes a http error wordpress minute: Sign up HTTP Get with 204 No Content: Is that normal up vote 15 down vote favorite 2 Is it a normal occurrence for an HTTP GET Request to have a response with status code 204 - No Content? Like, https://en.wikipedia.org/wiki/List_of_HTTP_status_codes is this semantically correct with respect to what an HTTP GET is supposed to accomplish? I know that a 204 - No Content is okay for an HTTP POST Request. For GET request, if no data is to be sent back, is the 204 status code appropriate? Should I use 404, or just stick to 200 for success but have an empty response? The use case for this question is a Java application that I am writing for Google App Engine. I am http://stackoverflow.com/questions/12807753/http-get-with-204-no-content-is-that-normal sending a request to a servlet, but the data to be sent back to the client will be transmitted through a Channel API socket instead of in the HTTP Response. Currently, my client sends a POST with no content in the request body, and waits for a 204 response back from the servlet before polling the Channel API socket. Because no data I being sent in the body of the request, I am debating whether it makes more sense for me to send a GET instead of a POST. google-app-engine http get http-status-codes channel-api share|improve this question edited Sep 15 '14 at 14:17 Tshepang 4,6941059103 asked Oct 9 '12 at 20:16 ecbrodie 3,52183677 add a comment| 2 Answers 2 active oldest votes up vote 29 down vote accepted 204 No Content The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant. According to the RFC part for the status code 204, it seems to me a valid choice for a GET request. A 404 Not Found, 200 OK with empty body and 204 No Content have completely different meaning, sometimes we can't use proper status code but bend the rules and they will come back to bite you one day or later. So, if you can use proper status code,
that the request was received and http://100pulse.com/http-statuscode/204.jsp understood, but that there is no need to send any data back. Why it Occurs The server has fulfilled the request but does not http://www.restapitutorial.com/httpstatuscodes.html need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of http error entity-headers, which if present, SHOULD be associated with the requested variant.The 204 response MUST NOT include a message-body, and thus is always terminated by the first empty line after the header fields. What it Means If the client is a user agent, it SHOULD NOT change its http error code document view from that which caused the request to be sent. This response is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent's active view.

consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) Wikipedia Request received, continuing process. This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions. 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. Wikipedia This means that the server has received the request headers, and that the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). If the request body is large, sending it t
