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 retri

Keep your inventory in check with barcode software.What is 404, anyway?Where did it come from?What do the numbers mean?What are the other status codes?How can I use status codes? What does 404 mean? 404 is an HTTP status code. Every time you visit a web page, your computer (the ‘client') is requesting data from a server using HTTP, or Hypertext Transfer Protocol. Before the web page is even displayed in your browser, the web server has sent the HTTP header, which contains the status code. Not surprisingly, your browser has sent the server its own headers, which contain a lot more information about you than you think!For a normal web page, the status is 200 OK. You don't see this because the server proceeds to send you the contents of the page. It's only when you encounter an error that you see the actual status code, such as 404 Not Found. So where do status codes come from? HTTP status codes were established by the World Wide Web Consortium (W3C) in 1992, as a part of the HTTP 0.9 spec. They were defined by Tim Berners-Lee, the same person who single-handedly invented the web and the first web browser in 1990. We at the 404 Research Lab like to think of him as The Man Who Made All Of This Possible.Berners-Lee based the HTTP status codes on FTP status codes, which were already well established by 1990; the official FTP spec is dated 1985, although FTP has actually been in use much longer. What do the numbers mean? Let's dissect 404.The first 4 indicates a client error. The server is saying that you've done something wrong, such as misspell the URL or request a page which is no longer there. Conversely, a 5xx error indicates a server-side problem. It also indicates an error which may be transient; if you try it again, it may work.The middle 0 refers to a general syntax error. This could indicate a spelling mistake.The last 4 just indicates the specific error in the group of 40x, which also includes 400: Bad Request, 401: Unauthorized, etc.It's been said that 404 was named after a room at CERN (if you read about Tim Berners-Lee above, you'll know that that's where the web began) where the original web serve
