// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: The application does not need to explicitly set the following
// headers: x-ms-date, Authorization.  These headers
// are automatically set by Chilkat.

// 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, 
// Delete Container will return 412 (Precondition failed).

// IMPORTANT: Delete this line, or insert a valid lease ID, otherwise the request
// will fail with a 400 status code..
