Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

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

// do not add the LocationConstraint.  Adding a LocationConstraint of "us-east-1"
// causes an error "The specified location-constraint is not valid."
