The Set-BCSecretKey cmdlet sets the cryptographic key used in 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.
