If a certain page on a website doesn't load for some reason or in case a link is broken, the site visitor will see an error page with a generic message. The page will have nothing in common with the rest of the site, that may make the visitor leave your website. A solution in such a case is a feature made available from some web hosting companies - the option to set up your own personalized error pages that will have the same design and style as your Internet site and which may contain any text or images you want depending on the particular error. There are four popular errors which could occur and they involve these so-called HTTP status codes - 400, when your browser sends a bad request to the web server and it cannot be processed; 401, if you are supposed to log in to see some web page, but you haven't done this yet; 403, if you don't have an authorization to see a specific page; and 404, when a link which you have clicked leads to a file that does not exist. In each of these scenarios, site visitors shall be able to see your customized content instead of a generic error page.
