If a certain 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 may make the visitor leave your site. A possible solution in this case is a function offered by some hosting providers - the ability to set your own custom-made error pages that shall have exactly the same design as your Internet site and which can contain any images or text that you would like based on the particular error. There are four popular errors which could occur and they involve the following so-called HTTP status codes - 400, when your Internet browser sends a bad request to the server and it cannot be processed; 401, in case you are supposed to log in to see some web page, but you haven't done so yet; 403, if you do not have an authorization to see a particular page; and 404, if a link that you have clicked leads to a file which does not exist. In all of these cases, site visitors will be able to see your custom made content rather than a generic error page.
