It includes codes from http status codes cheat sheet IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The http response example first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at http error wordpress a 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 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).

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[note 1] send a 1xx response to an HTTP/1.0 client except under experimental conditions.[4] 100 Continue The server has received the request headers and 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). Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request's headers, a client must send Expect: 100-continue as a header in its initial request and receive a 100 Continue status code in response before sending the body. The response 417 Expectation Failed indicates the request should not be continued.[2] 101 Switching Protocols The requester has asked the server to switch protocols and the server has agreed to do so.[5] 102 Processing (WebDAV; RFC 2518) A WebDAV request may contain many sub-requests involving file operations, requiring a long time to complete the request.

Responses are grouped in five classes: informational responses, successful responses, redirects, client errors, and servers errors. Information responses 100 Continue This interim response indicates that everything so far is OK and that the client should continue https://developer.mozilla.org/en-US/docs/Web/HTTP/Status with the request or ignore it if it is already finished. 101 Switching Protocol This code is sent in response to an Upgrade: request header by the client, and indicates that the protocol the server is switching too. It was introduced to allow migration to an incompatible protocol version, and is not in common use. Successful responses 200 OK The request has succeeded. The meaning of a success varies depending on the HTTP method: GET: The resource has been fetched and is transmitted in the message body. HEAD: The entity headers are in the message body. POST: The resource describing the result of the action is transmitted in the message body. TRACE: The message body contains the request message as received by the server 201 Created The request has succeeded and a new resource has been created as a result of it. This is typically the response sent after a PUT request. 202 Accepted The request has been received but not yet acted upon. It is non-committal, meaning that there is no way in HTTP to later send an asynchronous response indicating the outcome of processing the req

There are no required headers for this class of http://www.restapitutorial.com/httpstatuscodes.html status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST http://stackoverflow.com/questions/3290182/rest-http-status-codes-for-failed-validation-or-invalid-duplicate 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 http status 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).)

This class http status codes 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).

What status code should i send for requests failing validation or where a request is trying to add a duplicate in my database?

This is suggested in the book "RESTful Web Services". For double submit: 409 Conflict Update June 2014 The relevant specification used to be RFC2616, which gave the use of 400 (Bad Request) rather narrowly as The request could not be understood by the server due to malformed syntax So it might have been argued that it was inappropriate for semantic errors. But not any more; since June 2014 the relevant standard RFC 7231, which supersedes the previous RFC2616, gives the use of 400 (Bad Request) more broadly as the server cannot or will not process the request due to something that is perceived to be a client error share|improve this answer edited Sep 23 '14 at 17:50 Johannes Rudolph 23.8k875137 answered Jul 20 '10 at 13:05 deamon 25.5k61206323 1 Yes, the request body is part of the syntax. –deam
