Setting Up your own ErrorDocument Message
An "ErrorDocument" is the message that you see when you try to go to a web page that does not exist. The default ErrorDocument message looks like this:
File Not Found
The requested URL /xxxxxx.html was not found on this server.
(where xxxxxx.html is the name of the incorrect web page that you tried to visit).
The above ErrorDocument is not very pretty, and you may wish to make one of your own. This is how you do it:
Make a web page, name it badurl.htm and upload it into the same directory as your web pages..
