def create
  # The only things we need to handle in here (for now at least) are entries.
  # If there's been an update or a deletion, we just remove the cached timestamp.
  # The updated_at method which is included in ContentfulModel::Base in this gem
  # will check the cache first before making the call to the API.

  # We can then just use normal Rails russian doll caching without expensive API calls.
  request.format = :json
  update_type = request.headers['HTTP_X_CONTENTFUL_TOPIC']

  # All we do here is publish an ActiveSupport::Notification, which is subscribed to
  # elsewhere. In this gem are subscription options for timestamp or object caching,
  # implement your own and subscribe in an initializer.
