Demonstrates how to set an access policy for a vault (will overwrite the existing policy).

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

# Connect to the Amazon AWS REST server in the desired region.

port = 443
bAutoReconnect = True

# --------------------------------------------------------------------------
# Note: The above REST connection and setup of the AWS credentials
# can be done once.  After connecting, any number of REST calls can be made.
# The "auto reconnect" property passed to rest.Connect indicates that if
# the connection is lost, a REST method call will automatically reconnect
# if needed.
