If you have checked out lots of Internet sites, you've probably stumbled upon some error message from time to time. An error can occur in case the server cannot process a request (Error 400), if you must log in in order to 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 which is not on the web server (Error 404). Receiving this sort of messages may often be frustrating as the pages don't have anything in common with the actual Internet site. That’s why some website hosting providers allow you to use your own error pages that'll match the design of your own Internet site and that can have any content that you would like - information why the error has occurred, a suggestion how to proceed or even some humorous comment. Such a feature shall help you keep the visitor on the site irrespective of the error and the reason for it.
