If a particular page on an Internet 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 will have nothing in common with the rest of the website, that could make the visitor leave the website. A likely solution in this case is a feature made available from some website hosting service providers - the ability to set up your own custom error pages that will have identical design and style as your Internet site and which could contain any text or images that you would like dependent upon the particular error. There are 4 popular errors that may take place and they involve these so-called HTTP status codes - 400, when your web browser sends a bad request to the hosting server and it cannot be processed; 401, if you are supposed to log in to see a webpage, but you haven't done so yet; 403, if you do not have an authorization to see a specific page; and 404, when a link which you have clicked leads to a file that doesn't exist. In any of these cases, website visitors shall be able to see your custom made content as opposed to a generic error page.
