@ninacababaJul 04.2006 — #Not sure how to do it, but you could store all your stuff on site1.com and then on site2.com have an auto redirect or manual redirect.
Or a simpler solution could be that site2.com is given the same homepage as site1.com but all links are to site1.com
@LeeUJul 05.2006 — #You can assign one domain name to the server address and park or addon (depending upon your hosting account) the other one there. The parked one will forward to the assigned one. For example,
Assign "mydomain.com" to ns1.yourhost.com
then park/addon the other one to the same server:
assign "mydomain2.com" to ns1.yourhost.com
Your hosting account should have further information.
