// 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.

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

// <?xml version="1.0" encoding="utf-8"?>
// <StorageServiceProperties>
//     <Logging>
//         <Version>version-number</Version>
//         <Delete>true|false</Delete>
//         <Read>true|false</Read>
//         <Write>true|false</Write>
//         <RetentionPolicy>
//             <Enabled>true|false</Enabled>
//             <Days>number-of-days</Days>
//         </RetentionPolicy>
//     </Logging>

// Build the request:
