Rails - Aug 2010 - removing the www before a domain with Rails3?

Hello,
In Rails2 I used a middleware to redirect www.mydomain.tld to
mydomain.tld.
Something like this: http://pastie.org/1118140
It is in  Libs, with filename "no_www.rb".
I tryed to add as the first line of environment.rb as suggested in
here: http://edgeguides.rubyonrails.org/rails_on_rack.html

When it failed l put it in application,rb,  the first line after class
Application < Rails::Application in application.rb is:
config.middleware.use "NoWWW"
But when I try to run the app I get: C:/Ruby/lib/ruby/gems/1.9.1/gems/
activesupport-3.0.0.rc2/lib/active_support/inflector/methods.rb:124:in
`block in constantize'': uninitialized constant NoWWW (NameError)

Any idea how to use it? Unfortunately I can''t use mod_rewrite, since I
plan to put the app. on Heroku.

I have found the solution.
The config.middleware.use should be put into application.rb, and the /
lib is no longer loaded automatically so you need to load it, like
this:

  class Application < Rails::Application
    config.autoload_paths += %W(#{Rails.root}/lib)
    config.middleware.use "NoWWW"
    ...

Hope this helps someone.
