If a specific page on a website doesn't load for some reason or if a link is broken, the visitor shall see an error page with some generic message. The page will have nothing in common with the rest of the website, which may make the visitor leave your Internet site. A possible solution in cases like this is a feature offered by some website hosting companies - the option to set your own custom-made error pages that shall have the same design and style as your site and that could contain any text or images that you would like dependent upon the particular error. There are 4 popular errors which can take place and they involve the following 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 webpage, but you have not done so yet; 403, if you don't have a permission to view a certain page; and 404, in case a link which you have clicked leads to a file which does not exist. In any of these scenarios, visitors will be able to see your personalized content as opposed to a generic error page.
