Demonstrates how to find out the region of an S3 bucket. Lua

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

-- Connect to the Amazon AWS REST server using the correct region (in this example, "us-west-2")

-- The bucket name we want to know about is set in the HOST header.
-- In this example, we want to find the region for the "chilkat.qa" bucket.

-- Send the GET request to query the bucket location.

-- The result contains XML like this:
-- <?xml version="1.0" encoding="UTF-8"?>
