(JavaScript) S3 Download Specific Version of File

Demonstrates how to download a file from the Amazon S3 service using the versionId query parameter.

Note: This example requires Chilkat v9.5.0.89 or later. (A problem regarding AwsSubResources w/ downloads was fixed shortly after the v9.5.0.88 release.)

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.

var success = false;

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