I have a few strange situations where I need to have a completely
different Host header for some 2nd tier servers, but preserve host
doesn't help.
This simple patch allows one to change the Host: header sent to origin's
using the "proxy-host" env. It only works when preserve host is off.
Sorry most of it is format changes after adding the aditional if.
