// 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
