To the client, does each target look like it has a separate IP address?
Or, is iptables NAT smart enough to inspect the HTTP messages (even
SSL?) to route them?

I would think that it would be simpler to just have multiple IP
addresses and bind directly to port 80 on each of them.

If you are able to use multiple IPs, then the same technique will work
on Microsoft Windows... though I'm not sure why you'd want to run your
webapp on that platform :(
