Rails - May 2009 - redirect_to issue - lost port number

Hi all,

I found an issue with "redirect_to" by accident and hoped someone
could fill me in on what is happening. If I try to do a redirect to
somewhere that doesn''t exist, the port number will be dropped from the
url and I get a "Can''t connect to server" error.

http://localhost:3000/some-folder/

redirect_to "beans"

http://localhost/

I guess it''s defaulting to port 80, but can anyone tell me why?
