--
-- 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 <http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-create-https-ssl-load-balancer.html#configure_backendauth_clt Configure Back-end Instance Authentication> in the /Classic Load Balancer Guide/ . For more information about Proxy Protocol, see <http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-proxy-protocol.html Configure Proxy Protocol Support> in the /Classic Load Balancer Guide/ .
