response. 10.1 Informational 1xx 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. There are no http code 302 required headers for this class of status code. Since HTTP/1.0 did not define http status codes cheat sheet any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A

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).) 10.1.1 100 Continue The http 403 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. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status

e This is a list of Hypertext Transfer Protocol (HTTP) response http 404 status codes. It includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly http 502 used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 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 all of those are here https://en.wikipedia.org/wiki/List_of_HTTP_status_codes (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient

Like, is this semantically correct with respect to what http error 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 sending a request to a servlet, but the data to be sent http error codes 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, use it! I think the choice of GET or POST is very personal as both of them will do the work but I would
