According to pcsupport.about.com, In Internet Explorer, the message The webpage cannot be found usually indicates an HTTP 404 Internal Server Error but a 400 Bad Request error is another possibility. You can check to see which error IE is referring to by checking for either 404 or 400 in the title bar. Don't worry as it can be fixed thru redirecting urls to the working page or just reuploading the content of that same page.

When you have links which can not find by users and google bots then it shows 404 error. Always when you write post for your website never change its link. If you will do this you have to suffer from 404 Error. But You can also redirect this to other links for more google it

The Web server returns the "HTTP404- File not found"errormessage when it cannot retrieve the page that was requested. The following are some common causes of thiserrormessage: The requested file has been renamed. The requested file has been moved to another location and/or deleted.

404 is a frequently-seen status code that tells a Web user that a requested page is "Not found." 404 and other status codes are part of the Web's Hypertext Transfer Protocol ( HTTP ), written in 1992 by the Web's inventor, Tim Berners-Lee. He took many of the status codes from the earlier Internet protocol for transferring files, the File Transfer Protocol ( FTP .)

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.


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.


above, you’ll know that that’s where the web began) where the original web servers were located. However, Tom S. tells us:

“Having visited CERN myself, I can tell you that Room 404 is not on the fourth floor – the CERN office numbering system doesn’t work like that – the first digit usually refers to the *building* number (ie. building 4), and the second two to the office number. But, strangely, there is no room “04” in building “4”, the offices start at “410” and work upwards – don’t ask me why. Sorry to disappoint you all, but there is no Room 404 in CERN – it simply doesn’t exist, and certainly hasn’t been preserved as “the place where the web began”. In fact, there *is* a display about this, including a model of the first NeXT server, but the whole “Room 404? thing is just a myth.”

According to the W3C, 404 Not Found is only supposed to be used in cases where the server cannot find the requested location and is unsure of its status. If a page has permanently been deleted, it is supposed to use 410: Gone to indicate a permanent change. But has anyone ever seen 410? It must be 404…

How can I use status codes?


If you have access to the logfiles for your website, take a look at them. You’ll find that one of the fields is the HTTP status code. Look and see if anyone visiting your site got a 404. If you notice that there are consistent errors, look and see what the referring document is. Do you have a broken link on your site? Does another site link to you with a misspelled URL? These are things you can correct easily, which will help prevent 404 errors on your website

Is this error referring to a broken link in the site? I remember having come across this in one site recently and since I didn’t know about it so I just exited and went back to the home page. It is the site of a major news network. Perhaps they had a mistake in the uploading of news article hence that error appeared. It was not the first time for that news network.
