Thank you for this, it's a decent start for me personally. I was previously using the DNS director in Varnish 3.x to do this which was removed in 4.x. The longer time goes on the more risk it is to be running older software so this has been a great help.
Oddly enough I'd never really considered nginx for the job despite using it to reverse proxy elsewhere. Sometimes you just need a poke in the right direction :)
Now I just need to figure a way to specify *.internaldomain so that nginx resolves www.example.com.internaldomain - where www.example.com is grabbed from the requested Host: header
