# This controller is used for API v2 through api endpoint (/api/v2/graphql)
# and through the web interface (/graphql). When used through the web interface,
# we use connected administrateur to authenticate the request. We want CSRF protection
# for the web interface, but not for the API endpoint. :null_session means that when the
# request is not CSRF protected, we will not raise an exception,
# but we will provide the controller with an empty session.
