As I understand it, you must create multiple IP addresses for the web
server. What happens is, first the host name is resolved into a IP
address by the client, and then the client connects to the address.
There is no way for the server to figure out what DNS name was used to
connect, just the address. You'll have to use the alias option of
ifconfig to assign a network card several IP addresses, and then bind
each address to a specific hostname, and then set up Apache with
Virtual Host directives for each address.
The ifconfig command to add an alias is
ifconfig ed? inet 200.100.100.5 netmask 0xffffffff alias
I hope this helps a bit.
