404 pages display when someone tries to access a page on your website that doesn't exist.
Our hosting accounts allow you to use your home page as your 404 page, or you can create a custom one.
Server-side scripts, such as ASP.NET and PHP, might not work on custom 404 pages because of how Web server software (i.e. IIS and Apache) handles them.
Error docs must be web-visible, i.e. in your
httpdocs directory or hosted elsewhere.
