Replaces the current set of policies associated with a port on which the back-end server is listening with a new set of policies. After the policies have been created using CreateLoadBalancerPolicy, they can be applied here as a list. 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.

NOTE: The SetLoadBalancerPoliciesForBackendServer replaces the current set of policies associated with the specified instance port. Every time you use this action to enable the policies, use the PolicyNames parameter to list all the policies you want to enable.

You can use DescribeLoadBalancers or DescribeLoadBalancerPolicies action to verify that the policy has been associated with the back-end server.
