The web site hosting server will typically generate a "404 http error 404. the requested resource is not found. Not Found" web page when a user attempts to follow a broken or dead link; hence the 404 error is one of the most recognizable errors encountered on the World Wide Web.

the code 404, the first digit indicates a client error, such as a mistyped Uniform Resource Locator (URL). The following two digits indicate the specific error encountered. HTTP's use of three-digit codes is similar to the use of such codes in earlier protocols such as FTP and NNTP. At the HTTP level, a 404 response code is followed by a human-readable "reason phrase". The HTTP specification suggests the phrase "Not Found"[1] and many web servers by default issue an HTML page that includes both the 404 code and the "Not Found" phrase. A 404 error is often returned when pages have been moved or deleted. In the first case, it is better to employ URL mapping or URL redirection by returning a 301 Moved Permanently response, which can be configured in most server configuration files, or through URL rewriting; in the second case, a 410 Gone should be returned. Because these two options require special server configuration, most websites do not make use of them. 404 errors should not be confused with DNS errors, which appear when the given URL refers to a server name that does not exist. A 404 error indicates that the server itself was found, but that the server was not able to retrieve the requested page. Custom error pages[edit] The Wi

Protocol (HTTP) response status codes. It includes codes from IETF internet standards, other 404 meaning IETF RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five http status codes cheat sheet 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 https://en.wikipedia.org/wiki/HTTP_404 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 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
response. 10.1 Informational 1xx 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. There are no required headers for this class of status code. Since HTTP/1.0 https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html did not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a https://www.prestashop.com/blog/en/404-not-found-error-how-to-fix-it/ 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 http error 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 interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected http error messages 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. 10.1.2 101 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 protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates that the client's request was successfully received, understood, and accepted. 10.2.1 200 OK The request has succeeded. The information returned with the response is dependent on the method used in the request, for example: GET an entity corresponding to the requested resource is sent in the response; HEAD the entity-header fields corresponding to the requested resource are sent in the resp
