    // User-defined metadata are name/value pairs, and are added to the HTTP request header.
    // Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
    // Note that Amazon S3 stores user-defined metadata keys in lowercase.

    // For example, to add genus=Hippocampus, we do this:
    http.SetRequestHeader(L"x-amz-meta-genus",L"Hippocampus");

    // Add a few more user-metadata key pairs.
    http.SetRequestHeader(L"x-amz-meta-species",L"big-belly seahorse");
    http.SetRequestHeader(L"x-amz-meta-habitat",L"shallow tropical and temperate waters");

    bool success = http.S3_UploadFile(localFilePath,contentType,bucketName,objectName);
