    // When usig the REST class to access an S3 bucket that has been created in a particular region,
    // there are three important things to remember:
    // 
    // 1) Connect to the domain that includes the region.  For example, instead of connecting to
    //    "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
    //    See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
    // 
    // 2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
    // 
    // 3) Include the region in request's Host header.
    // 

    // This example will upload to a bucket in the eu-central-1 region.
