Defined in:
lib/scooter/middleware/rbac_auth_token.rb

Overview

This middleware checks for tokens and adds them to the request when found. To include this correctly, you will need to pass the dispatcher itself to the initialize method so it can read if the dispatcher has tokens or not. Beyond just the token itself, it also checks the dispatcher if the instance variable send_auth_token_as_query_param is set to true. Otherwise, it will always attach it as an X-Authentication header.
