# When successful, the Azure Storage service will respond with a 200, 201, or 202 response status code,

# The status code depends on the operation:
#    Acquire: A successful operation returns status code 201 (Created).
#    Renew: A successful operation returns status code 200 (OK).
#    Change: A successful operation returns status code 200 (OK).

#    Break: A successful operation returns status code 202 (Accepted).
