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

loRest = CreateObject('Chilkat.Rest')

* Connect to the Amazon AWS REST server in the desired region.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1

* Provide AWS credentials.

lnSuccess = loRest.SetAuthAws(loAuthAws)

* --------------------------------------------------------------------------
* 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.
