Use apache with mod_proxy. This cannot be done with iptables, the 
hostname is not in the first packet (the SYN) that iptables sees, after 
that it is to late to do anything about it as you cannot suddenly rejank 
the connection to another host.

For https you will need dedicated ips, for http use mod_proxy.
