# See Global Unlock Sample for sample code.

# Important: For buckets created in regions outside us-east-1,
# there are three important changes that need to be made.
# See Working with S3 Buckets in Non-us-east-1 Regions for the details.

# Provide AWS credentials for the REST call.

# header to "gzip" or "deflate".  (this is optional)

# We can add an "Expect: 100-continue" header so that if the request is rejected
# by the server immediately after receiving the request header, it can respond
# and the client (Chilkat) can avoid sending the file data.
