I'm going to make the assumption that we are talking about a Rails app. The
easiest way I found was to call request.host_with_port within a controller
or a view. This will return the host name and the port number (if provided).

I use this approach to figure out which Google Maps api key to use in my
application (one for development work, another one for the "production"
site).

There is a very active mailing list for Ruby on Rails. You can get details
on how to subscribe by going to
http://groups.google.com/group/rubyonrails-talk?hl=en .

Hope this helps.
