# To call Delete Container on a container that has an active lease, specify the lease ID in this header. 
# If this header is not specified when there is an active lease, Delete Container will return 409 (Conflict). 
# If you specify the wrong lease ID, or a lease ID on a container that does not have an active lease,

# will fail with a 400 status code..
