Can I redirect to a URL that uses the port number in the request, as  
opposed to the port specified in `listen`? (so as to work with  
proxies/tunnels)

E.g., if I have `listen 444` and have a tunnel so that my client is  
surfing [http://localhost:4444](http://localhost:4444), I don’t want my redirects to send the  
client to [http://localhost:444](http://localhost:444), which is currently the case - I want  
the port number to be reflected back, not “canonicalized.”

Thanks in advance for any hints.

This seems to happen for all redirects (e.g. rewrites), but if it  
makes any difference, the particular redirect I’m interested in is  
from

location /foo { alias /…/foo; }

Requests to /foo get redirected to /foo/ (but with the wrong port  
number, as described below).
