-- Replaces the set of policies associated with the specified port on which
-- the EC2 instance is listening with a new set of policies. At this time,
-- only the back-end server authentication policy type can be applied to
-- the instance ports; this policy type is composed of multiple public key
-- policies.
--
-- Each time you use @SetLoadBalancerPoliciesForBackendServer@ to enable
-- the policies, use the @PolicyNames@ parameter to list the policies that
-- you want to enable.
--
-- You can use DescribeLoadBalancers or DescribeLoadBalancerPolicies to
-- verify that the policy is associated with the EC2 instance.
--
-- For more information about enabling back-end instance authentication,
-- see
