Otherwise (i.e., the conditional GET used a weak validator), the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers. The new URI is not a substitute reference for the originally requested resource. weblink

Not observing these limitations has significant security consequences. 10.3.7 306 (Unused) The 306 status code was used in a previous version of the specification, is no longer used, and the code is reserved. 10.3.8 307 Temporary Redirect The requested resource resides temporarily under a different URI. For example, web servers such as Apache or Nginx produce two files called access.log and error.log that can be scanned for relevant information Keep in mind that HTTP status code definitions are part of a standard that is implemented by the application that is serving requests. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response. IETF. https://www.w3.org/Protocols/HTTP/HTRESP.html

Wikipedia The 4xx class of status code is intended for cases in which the client seems to have erred. Whenever a resource conflict would be caused by fulfilling the request. In a POST request, the response will contain an entity describing or containing the result of the action.[7] 201 Created The request has been fulfilled, resulting in the creation of a new resource.[8] 202 Accepted The request has been accepted for processing, but the processing has not been completed.

If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead. 10.4.5 404 Not Found The server has not found anything matching the Request-URI. Http Response Example CSGNetwork.com. 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. learn this here now However, this specification does not define any standard for such automatic selection.

Wikipedia The server cannot meet the requirements of the Expect request-header field. 418 I'm a teapot (RFC 2324) Wikipedia This code was defined in 1998 as one of the traditional IETF April Fools' jokes, in RFC 2324, Hyper Text Coffee Pot Control Protocol, and is not expected to be implemented by actual HTTP servers. Http Code 403 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 status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable. 10.4.6 405 Method Not Allowed The method specified in the Request-Line is not allowed for the resource identified by the Request-URI.

Http Response Example

The server MAY close the connection to prevent the client from continuing the request. news It indicates that a resource has permanently gone (a 404 status code gives no indication if a resource has gine permanently or temporarily), and no new address is known for it.411 - Length RequiredThe 411 status code occurs when a server refuses to process a request because a content length was not specified.412 - Precondition FailedA 412 status code indicates that one of the conditions the request was made under has failed.413 - Request Entity Too LargeThe 413 status code indicates that the request was larger than the server is able to handle, either due to physical constraints or to settings. Http Status Code 400 This typically occurs in the following situations: The network connection between the servers is poor The backend server that is fulfilling the request is too slow, due to poor performance The gateway or proxy server's timeout duration is too short Conclusion Now that you are familiar with the most common HTTP error codes, and common solutions to those codes, you should have a good basis for troubleshooting issues with your web servers or applications. Http Status Codes Cheat Sheet The 511 status SHOULD NOT be generated by origin servers; it is intended for use by intercepting proxies that are interposed as a means of controlling access to the network.

This rare condition is only likely to occur when a client has improperly converted a POST request to a GET request with long query information, when the client has descended into a URI "black hole" of redirection (e.g., a redirected URI prefix that points to a suffix of itself), or when the server is under attack by a client attempting to exploit security holes present in some servers using fixed-length buffers for reading or manipulating the Request-URI. 10.4.16 415 Unsupported Media Type The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method. 10.4.17 416 Requested Range Not Satisfiable A server SHOULD return a response with this status code if a request included a Range request-header field (section 14.35), and none of the range-specifier values in this field overlap the current extent of the selected resource, and the request did not include an If-Range request-header field. (For byte-ranges, this means that the first- byte-pos of all of the byte-range-spec values were greater than the current length of the selected resource.) When this status code is returned for a byte-range request, the response SHOULD include a Content-Range entity-header field specifying the current length of the selected resource (see section 14.16). nginx 1.9.5 source code.

Http 404 Note: RFC 1945 and RFC 2068 specify that the client is not allowed to change the method on the redirected request. If a Content-Length header field is present in the response, its value MUST match the actual number of OCTETs transmitted in the message-body. - Date - ETag and/or Content-Location, if the header would have been sent in a 200 response to the same request - Expires, Cache-Control, and/or Vary, if the field-value might differ from that sent in any previous response for the same variant If the 206 response is the result of an If-Range request that used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers.

The server MUST send an Upgrade header field in a 426 response to indicate the required protocol(s) (Section 6.7 of [RFC7230]). 428 Precondition Required The origin server requires the request to be conditional.

The Location field gives the URI of the proxy. Dies ist ein 'Catch-All (Sammel)'-Fehler, der vom Webserver erzeugt wird. This may include annotation information about the object, for example. Http 502 RFC 1945.

Other services may wish to implement the 429 Too Many Requests response code instead. 422 Unprocessable Entity (WebDAV) The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. The response MUST include the following header fields: Date, unless its omission is required by section 14.18.1 If a clockless origin server obeys these rules, and proxies and clients add their own Date to any response received without one (as already specified by [RFC 2068], section 14.19), caches will operate correctly. If the server does not know, or has no facility to determine, whether or not the condition is permanent, the status code 404 (Not Found) SHOULD be used instead. No indication is given of whether the condition is temporary or permanent.

The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. Retrieved August 30, 2016. ^ Stewart, Mark; djna.

This response is cacheable unless indicated otherwise. These status codes are applicable to any request method. ArcGIS Server SOAP SDK. ^ "HTTP Error Codes and Quick Fixes". 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.

If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued.
