Overview
If you have registered with a domain name registrar several domain names that you would like to point to the same web site that you host on this server, you should set up domain aliases.
If you need to serve several domain names that point to a web site hosted on another server, you should set up domain forwarding: see the Serving Domain Names for Sites Hosted on Other Servers (Domain Forwarding) section for instructions.
