Azure Storage: Delete Container

Azure Storage Blob Service REST API: Sample code to mark a container for deletion. The container and any blobs contained within it are later deleted during garbage collection. Zig

    // See also: https://msdn.microsoft.com/en-us/library/azure/dd179408.aspx

    // See Global Unlock Sample for sample code.

    // 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).

    // will fail with a 400 status code..
