If you have browsed loads of Internet sites, you've probably stumbled upon some error message from time to time. An error could take place in case the web hosting server can't process a request (Error 400), if you must log in to see some content and you have not done so (Error 401), if you aren't allowed to access some webpage (Error 403) or if a link leads to a file which is not on the web server (Error 404). Receiving this kind of messages could sometimes be frustrating because the pages have nothing in common with the actual Internet site. That’s why some web hosting providers permit you to apply your own error pages that'll match the design of your own Internet site and which may have any content that you would like - info why the error has taken place, a suggestion how to handle it or even some funny remark. This kind of feature will help you keep the visitor on the site regardless of the error and the reason for it.
