In the code 404, the first digit indicates a client error, such as a custom 404 error page returns 200 status 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

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 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 http://www.htmlgoodies.com/beyond/reference/article.php/3472591/How-Do-I-Create-a-Custom-404-Error-Page.htm 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. Better yet, ask them if you might mess things up by doing this. Your .htaccess File This is the file that will do the trick for you. You should already have one waiting inside of your Web site directory. If you don't, then you'll need to create it. FTP into your server so you're looking at the top level directory where you store your Web page files

He took many of the status codes from the earlier Internet protocol for transferring files, the File Transfer 404 error Protocol ( FTP .) What 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 404 error page note to the Webmaster so that the 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.

Also, if you are deleting a popular but out-of-date post, consider deleting the body of the post, and replacing it with a link referring visitors to the new page. Understanding Web Error Handling Visitors encounter errors at even the best websites. As site administrator, you may delete out-of-date posts, but another website may have a link to your inside page for that post. When a user clicks on a link to a missing page, the web server will send the user an error message such as 404 Not Found. Unless your webmaster has already written custom error messages, the standard message will be in plain text and that leaves the users feeling a bit lost. Most users are quite capable of hitting the back key, but then you've lost a visitor who may not care to waste their time hunting for the information. So as not to lose that visitor, at the very least, you'll want your custom message to provide a link to your home page. The friendly way to handle errors is to acknowledge the error and help them find their way. This involves creating a custom Error Page or editing the one that came wi
