For a variety of different errors, visitors shall see your custom content, which could be informative or humorous, in accordance with your personal preference, and that will match the overall style and design of your website, so the pages will not appear as if they aren't part of your Internet site at all. You may use this option for numerous errors - 400 (Bad request), 401 (Unauthorized), 403 (Forbidden) and 404 (File not Found).
