It includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used http error wordpress 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 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 http code 302 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

Informational status codes, rarely used – and generally only written to server logs. 200 to 299 Successful, only 200 frequently used – and generally only written to server logs. 300 to 399 Warning https://en.wikipedia.org/wiki/List_of_HTTP_status_codes – but the request may still be satisfiable. 400 to 499 Client Error, the request was invalid in some way. 500 to 599 Server Error, the server could not fulfill the (valid) request. 100 Range HTTP Error 100 Continue. Not really an “error”, this HTTP Status Code means everything is working fine. HTTP Error 101 Switching Protocols. Again, not really an “error”, this HTTP Status Code means http://john.foliot.ca/http-error-codes-and-what-they-mean/ everything is working fine. 200 Range HTTP Error 200 Success. This HTTP Status Code means everything is working fine. However, if you receive this message on screen, obviously something is not right… Please contact the server’s administrator if this problem persists. Typically, this status code (as well as most other 200 Range codes) will only be written to your server logs. HTTP Error 201 Created. A new resource has been created successfully on the server. HTTP Error 202 Accepted. Request accepted but not completed yet, it will continue asynchronously. HTTP Error 203 Non-Authoritative Information. Request probably completed successfully but can’t tell from original server. HTTP Error 204 No Content. The requested completed successfully but the resource requested is empty (has zero length). HTTP Error 205 Reset Content. The requested completed successfully but the client should clear down any cached information as it may now be invalid. HTTP Error 206 Partial Content. The request was canceled before it could be fulfilled. Typically the user gave up waiting for data and went to another page. Some download accelerator programs produce this error as they submit multiple requests to download a file at the same time. 300 Range HTTP Error 300 Multiple Choice
consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send http://www.restapitutorial.com/httpstatuscodes.html a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared http://www.webopedia.com/quick_ref/error.asp 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 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 http error 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 client except under experimental http error server 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 14.42), for a change in the application protoco
server soft error fatal exception error ECC Constraint Length FEC stop error hard error fatal error overflow error error correction Ever encounter an error on your way to a Web site? Of course you have. Don't worry; you'll be glad to know most of them have nothing to do with your PC. It's usually the other guy's fault -- the Web server, that is. Here are some of the more common errors you'll see while surfing the Internet. Errors on the Internet, and those annoying error messages, occur quite frequently — and can be quite frustrating — especially if you do not know the difference between a 404 error and a 502 error. Many times they have more to do with the Web servers you're trying to access rather than something being wrong with your computer. Here is a list of error messages (also called HTTP status codes) that you might encounter while surfing the Web and their respective meanings to help you figure out just what the problem is. List of HTTP Response Codes: 400 Bad File Request Usually means the syntax used in the URL is incorrect (e.g., uppercase letter should be lowercase letter; wrong punctuation marks). 401 Unauthorized Server is looking for some encryption key from the client and is not getting it. Also, wrong password may have been entered. Try it again, paying close attention to case sensitivity. 403 Forbidden/Access Denied Similar to 401; special permission needed to access the site -- a password and/or username if it is a registration issue. Other times you may not have the proper permissions set up on the server or the site's administrator just doesn't want you to be able to access the site. 404 File Not Found Server cannot find the file you requested. File has either been moved or deleted, or you entered the wrong URL or document name. Look at the URL. If a word looks misspelled, then c
