You can do this with a piece of Rack middleware. See https://gist.github.com/02c1cc8ce504033d61bf for an example of to do it in one.

You want to insert it before whatever the first item in the list that displays when you run rake middleware, which in my case is ActionDispatch::Static.

http://guides.rubyonrails.org/rails_on_rack.html may be somewhat helpful if you haven't been exposed to Rack in the Rails context before.
