The Rails Metal in Ruby on Rails 3

Question

I am using Ruby on Rails 3 and I would like to implement some Rack middleware.

I know (but maybe I am wrong!) that, before of version 3, there was the Rails Metal "system" to handle those. But now?!

Where in my Rails application I have to locate files to use for middleware purposes (before of version 3, if I am not wrong, the folder was named 'metal')? then, how I must state them in the application.rb file?
