Answers Franck Dernoncourt, PhD student in AI @ MITWritten 198w agohttp://arunmvishnu.com/articles/... :In the 1980′s a group of scientists at CERN (Switzerland) started working on what was to become the media revolution: the World Wide Web(WWW), 404 error message text or simply ‘the Web’. Their aim was to create a database infrastructure that offered 404 error message copy open access to data in various formats. They started developing their protocol called CERN’s internal network.In an office on the fourth 404 error message on pinterest floor (room 404), they placed the World Wide Web’s central database.Any request for a file was routed to that office, where two or three people would manually locate the requested files and transfer them, over the 404 error message wordpress network, to the person who made that request.When the database started to grow the number of requests grew and also the number of requests that could not be fulfilled, usually because the person who requested a file typed in the wrong name for that file.Soon these faulty requests were answered with a standard message: ‘Room 404: file not found’.Later, the manual processes were automated and people could directly query the database but

In simple terms HTTP code 404 means: Page Not Found. But HTTP 404 is actually two phrases: Client Error and Not Found. The first 4 is the error class (Client Error), and 04 is the specific error (Not Found).source: http://www.evs-translations.com/...1.9k Views · View UpvotesView More AnswersRelated QuestionsTh

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 serve

Well it all started http://www.techrepublic.com/article/geek-trivia-404-letter-words/ with a group of CERN (Switzerland) scientists who began working on something which would revolutionize the future: the World Wide Web(WWW), or simply ‘the Web’. Their aim was to create a database infrastructure that allowed access to data (text, picture, video etc) in various formats through a network. And in an office on the fourth floor (room 404), they error message placed the Internet's central database: any request for a file was routed to that office, where two or three people would manually locate the requested files and transfer them, over the network, to the person who made that request. Although restricted to CERN's internal network initially, it was soon extended for outside requests as well. And as the database grew, so did the number of requests and also the number of requests that 404 error message couldn't be fulfilled - the most common problem being wrong file name requests. Soon these faulty requests were answered with a standard message: Room 404: file not found. Later, the manual processes were automated and people could directly query the database but the error message remained the same "404: file not found" The room number remained in the error codes of the official release of HTTP (Hyper Text Transfer Protocol) and is still displayed when a browser makes a faulty request to a Web server. I so much wish I was also part of that group which silently made the Internet possible... Do you? Also see: Worlds funniest 404 error pages.

By Jay Garmon | April 2, 2007, 5:00 PM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus The time has come to celebrate yet another of those all-too-unrecognized geek-centric holidays (which I may have just made up): 404 Day! Every April 4th, Web surfers of every persuasion should take time out to celebrate that one universal experience of all Internet consumers and professionals — the 404 Page Not Found error. No matter which sites you frequent, which ISP you use, or which operating end of the browser zealot spectrum you fall on, we've all had our share of 404s. So, where did the 404 come from (besides the server, of course)? Like pretty much everything World Wide Web-related, the 404 is an official component of the Hypertext Transfer Protocol (HTTP) specification ratified by the World Wide Web Consortium (W3C). It first appeared in the version 0.9 HTTP spec, adopted in 1992. If you track down that document, you'll notice a rather telling signature: TimBL. That's the byline of one Tim Berners-Lee, he of the "I invented the World Wide Web and the first Web browser" fame. The same guy who made the modern Web page possible also invented the Page Not Found. Genius though he was, Berners-Lee didn't spin the HTTP status codes out of whole cloth but based them on the preexisting File Transfer Protocol (FTP) status codes. If you compare the two code listings, you'll find only 10 overlapping codes: 100, 200, 202, 425, 426, 500, 501, 502, 503, and
