I'm not quite sure, as I can't recreate this in the demo Rails apps
I'm running. You don't have it using an absolute URL (with hostname)
rather than just the usual relative URLs / path only URLs Rails puts
out, do you? If so, can you tell me how it's being constructed? In
theory the full hostname with the port number /should/ be getting
passed through to the backends so that this info can be used in
absolute URLs.
That said, I have just committed a new revision to trunk that stops
the port number being removed when working out the hostname to use. I
don't think this will have an effect, but you never know :)
