i am wondering is it possible for us to do our own customise error page message with our own contents.
e.g: my webpage url is http://www.myweb.com
when the user try to access http://www.myweb.com/dunno.htm.
. or kodasda.htm and etc
if the file doesn't exist in my server, is it possible for me to output my own contents like "The page you are trying to access is not valid. Please go to our site map" rather than the default contents show on the browser - Page Not Found..
or I must have a file in order to display my own contents ?
