Here's one useful snippet:
def (Before="").new(a,*o)Rack::Cascade.new(o<<a)end
This means that this app:
module App
use Before, Rack::File.new('public')
end
Will pass all requests through Rack::File.new('public') first, and
only proceed to App if that returns 404. This can be very useful for
serving static stuff in development mode (Rack::File will serve files
from the 'public' directory if it matches the URL; e.g.
./public/jquery.js will be available at localhost:3301/jquery.js)
Maybe we should add it to camping.rb?
