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

rest = Chilkat::CkRest.new()

# Connect to the Amazon AWS REST server in the desired region.
bTls = true
port = 443
bAutoReconnect = true
success = rest.Connect("glacier.us-west-2.amazonaws.com",port,bTls,bAutoReconnect)

# Provide AWS credentials.
authAws = Chilkat::CkAuthAws.new()
authAws.put_AccessKey("AWS_ACCESS_KEY")
authAws.put_SecretKey("AWS_SECRET_KEY")
authAws.put_ServiceName("glacier")

success = rest.SetAuthAws(authAws)

# --------------------------------------------------------------------------
# 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.
