// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// 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.
//
