In the code 404, the first digit indicates a client error, such error 404 text 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.

He took many of the status codes from the earlier Internet protocol for transferring files, the File Transfer Protocol ( FTP .) What https://en.wikipedia.org/wiki/HTTP_404 to Do If You Get a 404If the site no longer exists, there's nothing you can do. However, it only takes one mistyped character to result in a 404. See whether the ".htm" should be an ".html" or vice versa. If you're linking from a Web site, you can do a "View source" to make sure it wasn't miscoded. Whether or not it is, you may want to send a note to the Webmaster so that the http://whatis.techtarget.com/definition/404-status-code link can be fixed for the next users. How to Handle 404s If You Have a Web SiteHere are some things you can do: Use a Web site analysis tool such as Web Trends or Weblog to identify links that result in 404s, then fix the links. If you change the Uniform Resource Locator ( URL ) for a page on your site, retain the old URL as a redirect file, putting a message on it and inserting a META element with a REFRESH to change to the new URL in a specified number of seconds. You can create the page contents for a 404 status code page and substitute it for the 404 page that the browser usually provides. This will allow you to personalize the message and encourage the user to send a note to the Webmaster so that the situation can be fixed.

(WhatIs.com) internet meme - An internet meme is a cultural phenomenon that spreads from one person to another online, usually in the form of a video or an image with a brief message. (Whaasks for a page that’s simply not available on your site. The reason for this is that there may be a link on your site that was wrong or the page might have been recently removed from the site. As http://www.404errorpages.com/ there is no web page to display, the web server sends a page that simply says "404 Page not found". The 404 error message is an HTTP (Hypertext Transfer Protocol) standard status code. This "Not Found" response code indicates https://www.quora.com/What-is-a-way-to-solve-the-page-not-found-error that although the client could communicate to the server, the server could not find what was requested or it was configured not to fulfill the request. The 404 "Not Found" error is not the same as the "Server Not not found Found" error which you see whenever a connection to the destination server could not be established at all. The default 404 error page as shown on Internet Explorer is given below. HTTP Status Code Whenever you visit a web page, your computer will request data from a server through HTTP. Even before the requested page is displayed in your browser, the web server will send the HTTP header that has the status code. The status code provides information page not found about the status of the request. A normal web page gets the status code as 200. But we do not see this as the server proceeds to send the contents of the page. It’s only when there is an error, we see the status code 404 Not Found. Origin of Status Codes As a part of the HTTP 0.9 specifications, the World Wide Web Consortium (W3C) established HTTP status codes in 1992. Tim Berners-Lee, who invented the web and the first web browser in 1990, defined the status codes. List of Status Codes A brief overview of HTTP status codes is given below. Code Meaning Description 100 Continue Confirms the client about the arrival of the first part of the request and informs to continue with the rest of the request or ignore if the request has been fulfilled 101 Switching Protocols Informs the client about the server switching the protocols to that specified in the Upgrade message header field during the current connection. 200 OK Standard response for successful requests 201 Created Request fulfilled and new resource created 202 Accepted Request accepted, but not yet processed 203 Non-Authoritative Information Returned meta information was not the definitive set from the origin server. 204 No Content Request succeeded without requiring the return of an entity-body 205 Reset Content Request succeeded but require resetting of the document view that caused the request 206 Partial Content Partial GE
a way to solve the "page not found" error?UpdateCancelAnswer Wiki7 Answers Orestis DemetriouWritten 80w agoRetry the web page by pressing F5, clicking the refresh/reload button, or trying the URL from the address bar again.The 404 Not Found error might appear for several reasons even though no real issue exists, so sometimes a simple refresh will often load the page you were looking for.Check for errors in the URL. Often times the 404 Not Found error appears because the URL was typed wrong or the link that was clicked on points to the wrong URL.Move up one directory level at a time in the URL until you find something.For example, if www.web.com/a/b/c.htm gave you the 404 Not Found error, move up to www.web.com/a/b/. If you get nothing here (or an error), move up to www.web.com/a/. This should lead you toward what you're looking for or at least confirm that it's no longer available.Tip: If you have moved all the way up to the website's homepage, try to run a search for the information you're looking for. If the site doesn't have a search function, try navigating to the page you want using category links to dig deeper into the site.Search for the page at a popular search engine. It's possible that you simply have the entirely wrong URL in which case a quick Google or Bing search should get you where you want to go.If you do find the page you were after, update your bookmark or favorite to avoid the HTTP 404 error in the future.Clear your browser's cache if you have any indication that the 404 Not Found message might just be yours. For example, if you can reach the URL from your phone but not from your tablet, clearing the cache on your tablet's browser might help.You might also consider clearing your browser's cookies, or at least the one(s) involved with the website in question, if clearing the cache didn't work.Change th
