In 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 Wikimedia 404 message Web servers can typically be configured to display a customised 404 error page, including a more natural description, the parent site's branding, and sometimes a site map, a search form or 404 page widget. The protocol level phrase, which is hidden from the user, is rarely customized. Internet Explorer, however, will not

The first digit of the status code specifies one of five classes ce-40852-9 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 https://en.wikipedia.org/wiki/HTTP_404 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 requester has asked the server to sw

HTTP codes include error messages that describe the problems that visitors encounter. The codes are three-digit numbers.The following table represents the five classes of HTTP codes, divided into categories, by the first digit:First DigitDescription1, 2, or 3A fully functional request.4A client-side error. The most common codes span 400 to 404.5A server-side error. The most common codes span proxy error code 500 to 510.Note: For more information, read Wikipedia's List of HTTP status codes article.ErrorsErrorDescription4xx ErrorsThese errors result due to a problem with the client's request (for example, the browser), but often point to a problem on a website. For example, if a faulty link exists on your home page, and visitors click it, they receive a 404 error.We strongly suggest that you monitor these errors and investigate their causes. Because visitors most often see this error, we suggest that you customize these error pages in cPanel's Error Pages interface (Home >> Advanced >> Error Pages).400 Bad RequestThe user's request contains an incorrect syntax.401 UnauthorizedThe requested file requires authentication (a username and password).403 ForbiddenThe server will not allow the visitor to access the requested file. If a visitor receives this code in error, check the file's permission settings. You can also confirm whether the system protects the file in cPanel's Indexes interface (Home >> Advanced >> Indexes).404 Not FoundThe server did not find a visitor's requested file. This error commonly occurs when a visitor mistypes a URL.5xx ErrorsThese errors occur when a server cannot fulfill an apparently-v
» HTTP Status and Error Codes HTTP Status and Error Codes 3 Years Ago GlobalSCAPE 5 CuteFTP for Windows THE INFORMATION IN THIS ARTICLE APPLIES TO: All GlobalSCAPE products, all versions Refer to https://kb.globalscape.com/KnowledgebaseArticle11144.aspx for EFT-specific HTTP error codes DISCUSSION During your HTTP sessions, you'll receive various numbered codes from Web servers. When connected via HTTP, CuteFTP and HTTP servers to which you connect can display these codes in the log window. Some codes represent errors. Most others simply communicate the status of the connection. Here are brief explanations for the most common status and error codes. The list below are standard HTTP codes. Numbers outside this list are proprietary to the Server or Client that you are using. Error or Status Code Description 100 Series Informational - These status codes indicate a provisional response. The client should be prepared to receive one or more 1xx responses before receiving a regular response. 100 Continue. 101 Switching protocols. 200 Series Success - This class of status codes indicates that the server successfully accepted the client request. 200 The client request has succeeded. This status code indicates that the Web server has successfully processed the request. 201 Created. 202 Accepted. 203 Non-authoritative information. 204 No content. 205 Reset content. 206 Partial content. 300 Series Redirection - The client browser must take more action to fulfill the request. For example, the browser may have to request a different page on the server or repeat the request by using a proxy server. 302 Object moved. 304 Not modified. The client requests a document that is already in its cache and the document has not been modified since it was cached. The client uses the cached copy of the document, instead of downloading it from the server 307 Temporary redirect. 400 Series Client Error - An error occurs, and the client appears to be at fault. For example, the client may request a page that does not exist, or the client may not provide valid authentication information. 400 Bad request. 401 Access denied. 401.1 Logon failed. The logon attempt is unsuccessful, probably because of a user name or password that is not valid. 401.2 Logon failed due to server configuration. 401.3 Unauthorized due to ACL on resource. This indicates a problem with NTFS permissions. This error may occur even if the permissions are correct for the file that you are trying to access. For example, you see this error if the IUSR account does not have access to the C:\Winnt\System32\Inetsrv directory. 401.4 Authorization failed by filter. 401.5 Auth
