  # Using request.host which might be different than event['headers']['Host'] when config.app.domain is set.
  # This means that visiting the APIGW domain name directly will not prepend the stage name
  # to the helper method urls.  This is ok since the APIGW domain name is not used in production.
  # It's a compromise since we cannot pass the CloudFront host to APIGW.
  # Rather have the CloudFront user-friendly domain name work than APIGW domain name.
  # Examples:
  #   https://djvojd3em5.execute-api.us-west-2.amazonaws.com/dev/
  #   https://friendly.domain.com/
