If a specific page on a website does not load for some reason or in case a link is broken, the website visitor will see an error page with some generic message. The page shall have nothing in common with the rest of the website, which could make the visitor leave the website. A possible solution in cases like this is a function made available from some web hosting service providers - the option to set up your own customized error pages which will have the same design as your Internet site and which could contain any text or images that you would like dependent upon the particular error. There are four well-known errors that can take place and they involve the following so-called HTTP status codes - 400, when your Internet browser sends a bad request to the hosting server and it cannot be processed; 401, if you're supposed to log in to see a web page, but you have not done this yet; 403, if you do not have a permission to view a specific page; and 404, if a link which you've clicked leads to a file that doesn't exist. In all of these situations, website visitors will be able to see your custom content instead of a generic error page.
