  # key in initializers/session_store.rb
  # secret in initializers/secret_token.rb
  # We're doing this so that the same cookie is used across 
  # Resque Web and the Rails App

  # Typical warden setup but instead of having resque web handle
  # failure, we'll pass it off to the rails app so that devise
  # can take care of it.
