(HTTP) response status codes. It includes codes from IETF internet standards, other IETF RFCs, http response example other specifications, and some additional commonly 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 used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part http 422 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 protocol

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 https://developer.mozilla.org/en-US/docs/Web/HTTP/Status so far is OK and that the client should continue 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 t
refer to the target resource and its selected representation after the requested action was applied. For example, https://httpstatuses.com/204 if a 204 status code is received in response to a PUT request and the response contains an ETag header field, then the PUT was successful and the ETag field-value contains the entity-tag for the new representation of that target resource. The 204 response allows a server to indicate that the action http code has been successfully applied to the target resource, while implying that the user agent does not need to traverse away from its current "document view" (if any). The server assumes that the user agent will provide some indication of the success to its user, in accord with its own interface, and http no response apply any new or updated metadata in the response to its active representation. For example, a 204 status code is commonly used with document editing interfaces corresponding to a "save" action, such that the document being saved remains available to the user for editing. It is also frequently used with interfaces that expect automated data transfers to be prevalent, such as within distributed version control systems. A 204 response is terminated by the first empty line after the header fields because it cannot contain a message body. A 204 response is cacheable by default; i.e., unless otherwise indicated by the method definition or explicit cache controls1. 1 Calculating Heuristic Freshness RFC7234 Section 4.2.2 Source: RFC7231 Section 6.3.5 204 Code References Rails HTTP Status Symbol :no_content Go HTTP Status Constant http.StatusNoContent Symfony HTTP Status Constant Response::HTTP_NO_CONTENT Python2 HTTP Status Constant httplib.NO_CONTENT Python3+ HTTP Status Constant http.client.NO_CONTENT Python3.5+ HTTP Status Constant http.HTTPStatus.NO_CONTENT← Return to httpstatuses.com
