If a particular page on a site doesn't load for some reason or in case a link is not working, the visitor shall see an error page with some generic message. The page shall have nothing in common with the rest of the site, which can make the visitor leave your Internet site. A likely solution in cases like this is a feature made available from some hosting service providers - the option to set up your own customized error pages that shall have exactly the same style and design as your Internet site and that may contain any images or text that you'd like based on the specific 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 web server and it can't be processed; 401, if you are supposed to log in to see some page, but you have not done so yet; 403, if you don't have a permission to see a specific page; and 404, in case a link which you've clicked leads to a file which does not exist. In all of these cases, site visitors will be able to see your customized content as opposed to a generic error page.
