Cacheable Methods ..................................24 4.3. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. httpstatus. The message body is itself a protocol element; a sender MUST generate only CRLF to represent line breaks between body parts. http://orgias.org/http-status/http-error-codes-301.html

Differences between HTTP and MIME .....................89 A.1. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place. 203 Non-Authoritative Information The returned metainformation in the entity-header is not the definitive set as available from the origin server, but is gathered from a local or a third-party copy. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. Note: RFC 1945 and RFC 2068 specify that the client is not allowed to change the method on the redirected request.

Http Status Code 400

It is not appropriate to use 409 Conflict when the resulting state of the resource is as the user requested. 5xx Server Error Codes┬ These codes represent that the server, or gateway, has encountered an error or is incapable of performing the requested method. External links[edit] Wikimedia Commons has media related to HTTP. The request method was envisioned as applying semantics to a target resource in much the same way as invoking a defined method on an identified object would apply semantics.

User agents should display any included entity to the user.[31] 400 Bad Request The server cannot or will not process the request due to an apparent client error (e.g., malformed request syntax, too large size, invalid request message framing, or deceptive request routing).[32] 401 Unauthorized (RFC 7235) Similar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided. HTTP Working Group. ^ "Hypertext Transfer Protocol (HTTP/1.1): Semantics and Content, Section 6.4.7 307 Temporary Redirect". POST The POST method requests that the target resource process the representation enclosed in the request according to the resource's own specific semantics. Http 422 For example, the following examples are all equivalent, but the first is preferred for consistency: text/html;charset=utf-8 text/html;charset=UTF-8 Text/HTML;Charset="utf-8" text/html; charset="utf-8" Internet media types ought to be registered with IANA according to the procedures defined in [BCP13].

media-type = type "/" subtype *( OWS ";" OWS parameter ) type = token subtype = token The type/subtype MAY be followed by parameters in the form of name=value pairs. Http Status Codes Cheat Sheet Other patterns of content negotiation include "conditional content", where the representation consists of multiple parts that are selectively rendered based on user agent parameters, "active content", where the representation contains a script that makes additional (more specific) requests based on the user agent characteristics, and "Transparent Content Negotiation" ([RFC2295]), where content Fielding & Reschke Standards Track [Page 18] RFC 7231 HTTP/1.1 Semantics and Content June 2014 selection is performed by an intermediary. Error code response for missing or invalid authentication token. 402 Payment Required This code is reserved for future use. Do not handle the request as normal by ignoring the bad attribute.

This has the benefits of providing the user agent a resource identifier and transferring the representation via a method more amenable to shared caching, though at the cost of an extra request if the user agent does not already have the representation cached. 4.3.4. Http 403 Unless it was a HEAD request, the response SHOULD include an entity containing a list of available entity characteristics and location(s) from which the user or user agent can choose the one most appropriate. PUT ................................................26 4.3.5. Max-Forwards .......................................36 5.2.

Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). https://developer.mozilla.org/en-US/docs/Web/HTTP/Status Google Books. Http Status Code 400 June 1999. Http Response Example Procedure ..........................................81 8.4.2.

If the client continues sending data to the server after the close, the server's TCP stack will send a reset packet to the client, which may erase the client's unacknowledged input buffers before they can be read and interpreted by the HTTP application. 10.4.1 400 Bad Request The request could not be understood by the server due to malformed syntax. have a peek at these guys Wikipedia® is a registered trademark of the Wikimedia Foundation, Inc., a non-profit organization.

Subsequent requests by the client are permissible.[37] 405 Method Not Allowed A request method is not supported for the requested resource; for example, a GET request on a form which requires data to be presented via POST, or a PUT request on a read-only resource. 406 Not Acceptable The requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request.[38] See Content negotiation. 407 Proxy Authentication Required (RFC 7235) The client must first authenticate itself with the proxy.[39] 408 Request Timeout The server timed out waiting for the request. DNS) it needed to access in attempting to complete the request. check over here The client MAY repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message. 10.4.13 412 Precondition Failed The precondition given in one or more of the request-header fields evaluated to false when it was tested on the server.

Http 404 Note: Some sites issue HTTP 401 when an IP address is banned from the website (usually the website domain) and that specific address is refused permission to access a website. 402 Payment Required Reserved for future use. Retrieved 7 March 2015. ^ "Server Error Codes".

Unlike a 204 response, this response requires that the requester reset the document view.[13] 206 Partial Content (RFC 7233) The server is delivering only part of the resource (byte serving) due to a range header sent by the client.

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 client SHOULD continue with its request. This response MUST NOT use the multipart/byteranges content- type. Updates: 2817 greenbytes Category: Standards Track June 2014 ISSN: 2070-1721 Hypertext Transfer Protocol (HTTP/1.1): Semantics and Content Abstract The Hypertext Transfer Protocol (HTTP) is a stateless application- level protocol for distributed, collaborative, hypertext information systems. Http 502 However, some Web applications and frameworks use the 302 status code as if it were the 303. 303 See Other The response to the request can be found under a different URI and SHOULD be retrieved using a GET method on that resource.

Retrieved October 11, 2009. ^ a b "Using token-based authentication". Request Methods ................................................21 4.1. This specification defines two patterns of content negotiation that can be made visible within the protocol: "proactive", where the server selects the representation based upon the user agent's stated preferences, and "reactive" negotiation, where the server provides a list of representations for the user agent to choose from. http://orgias.org/http-status/http-error-codes-404-403.html Check Up Down.
