[Rails] Unable to get the domain in my routes.rb to map customroute tables per domain

[Nathaniel S. H. Brown]

I have two domains setup on my rails app:

example.COM and example.NET

I want to be able to have a case in the routes, that if the URL in the
location bar is example.NET to use this route:

if hostname.match(/NET/)
  map.connect '', :controller => 'special', :action => 'case'
else
  map.connect '', :controller => 'default', :action => 'index'
End

That way I can have a new root URL for example.NET, but use the same
application.

This should definitely be available as it is available through the
@request.domain(1) within the view. Question is, if its not available in a
default variable, how can I populate it manually? I checked out the CGI
module from Ruby, and it mentions to use the ENV['HTTP_HOST'] variable, but
that is empty. So I am led to believe that Rails gets the active domain
through some other mechanism, yet I am unable to find where this is done.

Thanks.
