What is 404 error & why use this?

[Worldeyeglasses]

The Error 404 "Page not found" is the error page displayed whenever someone asks for a page that's simply not available on your site. The reason for this is that there may be a link on your site that was wrong or the page might have been recently removed from the site. As there is no web page to display, the web server sends a page that simply says "404 Page not found".

The 404 (Not Found) error message is an HTTP standard response code showing that the client was able to communicate with a given server, but the server could not find what was requested.

A 404 error page may display when a customer tries to access a website or file within a website that isn't available or cannot be found. This may occur when a page name has been changed or moved, or when a web server is completely offline.
