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 retrieve the requested page. Custom

& 9 Most Common HTTP Errors Explained Published by Anna Monus,in Hosting Apart from the 404 error, how many other HTML error pages do you know about? Have you ever thought about what happens in the background when you see any of these HTML error pages on your screen? Those codes are meant to convey important information to the user. It can be useful to know them better, especially if you are a website owner. Using them properly reduces your bounce rate, improves your search engine ranking and gives you knowledge on the performance of your site. Understanding Status Codes Behind every error page you see on the web there is an HTTP status code sent by the web server. Status codes come in the format of 3 digit numbers. The first digit marks the class of the status code: 1XX status codes have informational purposes 2XX indicates success 3XX is for redirection None of these three classes result in an HTML error page as in this cases the client knows what to do and goes on with the task without hesitation. What we usually see are the 4XX and 5XX kind: 4XX represent client-side errors 5XXs indicate problems on the server side HTML error pages are displayed in these cases because the client has no idea about what how to move on. Let’s see what happens in the background when something goes south and what you can do about it.

It usually happens when the data sent by the browser doesn’t respect the rules of the HTTP protocol, so the web server is clueless about how to process a request containing a malformed syntax. Pin itWhen you see a 400 error page the reason is most likely that there’s something unstable on the client side: a not sufficiently protected operating system, an instable internet connection, a defective browser or a caching problem. So it’s always a good idea to test a bit your own PC before you contact the owner of the website. Open the same webpage in a different browser, clear the cache, and check if you are due with security updates. If you regularly meet
