-- Get the state for a routing control. A routing control is a simple
-- on\/off switch that you can use to route traffic to cells. When a
-- routing control state is On, traffic flows to a cell. When the state is
-- Off, traffic does not flow.
--
-- Before you can create a routing control, you must first create a
-- cluster, and then host the control in a control panel on the cluster.
-- For more information, see
-- <https://docs.aws.amazon.com/r53recovery/latest/dg/routing-control.create.html Create routing control structures>
-- in the Amazon Route 53 Application Recovery Controller Developer Guide.
-- You access one of the endpoints for the cluster to get or update the
-- routing control state to redirect traffic for your application.
--
-- /You must specify Regional endpoints when you work with API cluster
-- operations to get or update routing control states in Route 53 ARC./
--
-- To see a code example for getting a routing control state, including
-- accessing Regional cluster endpoints in sequence, see
-- <https://docs.aws.amazon.com/r53recovery/latest/dg/service_code_examples_actions.html API examples>
-- in the Amazon Route 53 Application Recovery Controller Developer Guide.
