If you have either a Deluxe, Premium, Unlimited, or Ultimate hosting account, you can add secondary domain names to your hosting account. Secondary domains have websites that work independently of the primary domain's hosted in separate folders. For more information, see What type of hosting account do I have?
At any time, you can change which folder your secondary domain names use for the root of their websites.
The secondary domain name now displays the index file you uploaded to that folder. For more information, see What file displays when someone browses to my domain name?
