    // See Global Unlock Sample for sample code.

    // Connect to the Azure Storage Blob Service
    var bTls = true;
    var port = 443;

    // This example will set logging properties.  The XML body of the request
    // will look like this:

    //             <Days>number-of-days</Days>
    //         </RetentionPolicy>
    //     </Logging>
