So I have one linux machine (machine one) with apache serving multiple domains (five+ virtuals.) One is getting particularly busy, and I want to move that one to a new "machine two" with some additional oomph. My router has one "send HTTP/HTTPS to this IP" setting, so everything has to go to that single IP from the router.
So my question is: Is there a way to forward or otherwise send along HTTP/HTTPS to "machine two" from "machine one" when the first, primary recipient of the HTTP/HTTPS data does not resolve to a domain hosted on "machine one"?
