how to change "Apache is functioning normally" page

[2hamed]

I have a VPS with DirectAdmin installed on it and it is working perfectly fine. the only thing that bugs me is that when I go to my default domain (novinhost.net) I see the message "Apache is functioning normally" appear on the screen. what I want is to make that particular domain point to one of my other domains(novinhost.ir).

what can I do to achieve this?

Replace the file at /var/www/html/index.html, to do a redirect, or add one using some other method.
