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