Title: Needed to change how we preserve the hosts; must preserve port number

First of all, thanks for writing this -- it came in super handy at work today.

I have a rather unusual setup as I am trying to run my reverse proxy on port 9292. I set :preserve_host => true in my options, but :preserve_host only sets the hostname part of the HOST environment variable. I needed hostname:port_number.
