Even 404 error page text 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 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

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 s

By Joe Burns Tweet Ah, the aggravating 404 error page. You've seen it. There you are, surfing in your favorite search engine when you happen upon just the thing you're looking for. You click: (***Raspberry Sound Effect***) Nothing but a white page with the words "404 404 error page Error" and some other techie-sounding speak beneath. What's even more cheesy about the error code is that it really doesn't tell you what the problem is. Basically you've been informed that the server cannot find what you want. It doesn't tell you why, how to fix it, or where to go from that point. You really don't have much choice but to hit your BACK button, call the computer a dirty name, and try again. But then you see it--a server that's set up with its own special 404 error page that politely apologizes and offers you links to e-mail site administrators and maybe a site search engine. Now that's class! So I waltzed into the office of the Webmaster at work and asked how it was done. I was stunned at how easy it is to set up. Want one of your own? Here's how. You'd Best Ask First I'm going to offer you a very basic fix to this problem, but you'd best ask your system people if they want you doing this first.
