If you have browsed loads of websites, you've probably stumbled upon some error message now and again. An error can take place if the web hosting server cannot process a request (Error 400), if you must log in so that you can see some content and you have not done so (Error 401), if you aren't permitted to access a page (Error 403) or if a link leads to a file that is not on the hosting server (Error 404). Receiving this type of messages could often be annoying since the pages don't have anything in common with the actual Internet site. That’s why some website hosting service providers allow you to set your own error pages that'll match the style of your own Internet site and which may have any content which you'd like - details why the error has taken place, a suggestion how to handle it or even some amusing remark. This type of function will help you keep the visitor on the site regardless of the error and the reason for it.
