    // 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("x-amz-meta-genus","Hippocampus");

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