-- | Replaces the set of policies associated with the specified port on which the
-- back-end server is listening with a new set of policies. At this time, only
-- the back-end server authentication policy type can be applied to the back-end
-- 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 back-end server.
