[users@httpd] Page display on default html page

[Jos Chrispijn]

I have created a default html site that is displayed when visitors typed 
in a domain that I own, but for which I haven't yet created a website for.

As this default site has a domain name that is not the name that a 
visitor typed in, I would like to disply that domain name on its index 
page like

'You requested'

www.adomain.com

'but unfortunately it doesn't have a site page yet'

Can someone tell me how I can do something like this without java script?

Thanks!
Jos
