[Lilug] port forward by domain?

[Justin Dearing]

Ken,
Impossible for the other protocols.

Multiple domains on a single IP going to different locations works because
apache looks at the domain in the http header (levels 5-7 of the OSI model)
This is why each ssl site needs its own IP address with apache (or IIS or
whatever). Since each website has its own ssl cert, the http header wont get
decrypted until after it knows what domains to go to and what cert to use.

In the case of apache having one domain on a separate box, have the main
server redirect to that, or just buy a second IP address.

Regards,

Justin Dearing
