The Import-BCSecretKey cmdlet imports the cryptographic key that BranchCache uses for the generation of segment secrets. Use this cmdlet when deploying BranchCache enabled
content servers in a cluster or behind a network load balancer. If a file or webpage exists on multiple content servers, then each server must use the same secret key;
otherwise, each copy of the file will be cached separately within the branch office.
Use the Export-BCSecretKey cmdlet to export the secret key from one server to a file. Import the contents of this file using this cmdlet.
