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 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 http 422 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).

send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST http code 302 be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a http 409 100 (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 https://en.wikipedia.org/wiki/List_of_HTTP_status_codes 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 http://www.restapitutorial.com/httpstatuscodes.html 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 to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the request's headers alone, a client must send Expect: 100-continue as a header in its initial request and check if a 100 Continue status code is received in response before continuing (or receive 417 Expectation Failed and not continue). 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section

Responses are grouped in five http error codews 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 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 20
1xx: Informational - Request received, continuing process 2xx: Success - The action was successfully received, understood, and accepted 3xx: Redirection - Further action must be taken in order to complete the request 4xx: Client Error - The request contains bad syntax or cannot be fulfilled 5xx: Server Error - The server failed to fulfill an apparently valid request Available Formats CSV Value Description Reference 100 Continue [RFC7231, Section 6.2.1] 101 Switching Protocols [RFC7231, Section 6.2.2] 102 Processing [RFC2518] 103-199 Unassigned 200 OK [RFC7231, Section 6.3.1] 201 Created [RFC7231, Section 6.3.2] 202 Accepted [RFC7231, Section 6.3.3] 203 Non-Authoritative Information [RFC7231, Section 6.3.4] 204 No Content [RFC7231, Section 6.3.5] 205 Reset Content [RFC7231, Section 6.3.6] 206 Partial Content [RFC7233, Section 4.1] 207 Multi-Status [RFC4918] 208 Already Reported [RFC5842] 209-225 Unassigned 226 IM Used [RFC3229] 227-299 Unassigned 300 Multiple Choices [RFC7231, Section 6.4.1] 301 Moved Permanently [RFC7231, Section 6.4.2] 302 Found [RFC7231, Section 6.4.3] 303 See Other [RFC7231, Section 6.4.4] 304 Not Modified [RFC7232, Section 4.1] 305 Use Proxy [RFC7231, Section 6.4.5] 306 (Unused) [RFC7231, Section 6.4.6] 307 Temporary Redirect [RFC7231, Section 6.4.7] 308 Permanent Redirect [RFC7538] 309-399 Unassigned 400 Bad Request [RFC7231, Section 6.5.1] 401 Unauthorized [RFC7235, Section 3.1] 402 Payment Required [RFC7231, Section 6.5.2] 403 Forbidden [RFC7231, Section 6.5.3] 404 Not Found [RFC7231, Section 6.5.4] 405 Method Not Allowed [RFC7231, Section 6.5.5] 406 Not Acceptable [RFC7231, Section 6.5.6] 407 Proxy Authentication Required [RFC7235, Section 3.2] 408 Request Timeout [RFC7231, Section 6.5.7] 409 Conflict [RFC7231, Section 6.5.8] 410 Gone [RFC7231, Section 6.5.9] 411 Length Required [RFC7231, Section 6.5.10] 412 Precondition Failed [RFC7232, Section 4.2] 413 Payload Too Large [RFC7231, Section 6.5.11] 414 URI Too Long [RFC7231, Section 6.5.12] 415 Unsupported Media Type [RFC7231, Section 6.5.13][RFC7694, Section 3] 416 Range Not Satisfiable [RFC7233, Section 4.4] 417 Expectation Failed [RFC7231, Section 6.5.14] 418-420 Unassigned 421 Misdirected Request [RFC7540, Section 9.1.2] 422 Unprocessable Entity [RFC4918] 423 Locked [RFC4918] 424 Failed Dependency [RFC4918] 425 Unassigned 426 Upgrade Required [RFC7
