Before adding a secondary domain name, we advise you to point your add-on domain name server to your main domain name server. You may also need to wait for domain propagation. It usually takes between 12 and 24 hours.
1. Log into your SiteWorx account. (eg: www.example.com:2443/siteworx/ )
2. Under "SiteWorx Menu", click the "Hosting Features" menu item if it is not already open.
3. Click the "Domain" menu item and then click on the "Secondary" option.
4. Under the "Add Domain" tab, enter your domain in "Domain" field (e.g. example.com).
5. Click the "Add" button.
You should see a success message notifying you that your secondary domain has been added.
