//  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.
//

//  Connect to the Amazon AWS REST server.

//  Provide AWS credentials for the REST call.

//  Set the bucket name via the HOST header.
//  In this case, the bucket name is "chilkateufrankfurt" (which was created in the eu-central-1 region)

//  Did we get a 200 response indicating success?

    destroy loo_Rest
