Root Domain to WWW redirection in Rails 3.1 before forcing SSL on Heroku

forcessl.rb

# in config/environments/production.rb 
# config.force_ssl = true
# config.middleware.use "Forcessl"
#  Make sure redirection happens before forcing ssl
# config.middleware.insert_before 'Rack::SSL', 'Forcessl' 

# in lib/forcessl.rb
# change *. to your domain

class Forcessl
  def initialize(app)
    @app = app
  end
  
  def call(env)
    request = Rack::Request.new(env)
    if request.host.starts_with?("*.com")
      [301, {"Location" => request.url.sub("//*.com", "//www.*.com")}, self]
    else
      @app.call(env)
    end
  end

  def each(&block)
  end
end
