If you have looked at many Internet sites, you have probably encountered some error message every now and then. An error could take place in case the hosting server cannot process a request (Error 400), if you need to log in so that you can see some content and you have not done so (Error 401), if you are not allowed to access a webpage (Error 403) or when a link leads to a file that is not on the website hosting server (Error 404). Receiving this type of messages could sometimes be aggravating as the pages have nothing in common with the actual website. That’s why some hosting providers allow you to use your own error pages that will match the design of your own website and which can have any content which you'd like - details why the error has appeared, a suggestion what you can do or even some amusing comment. This type of function shall help you keep the visitor on the website irrespective of the error and the reason for it.
