(JavaScript) S3 Rename File
Demonstrates how to rename a file on Amazon S3.
Renaming an object (file) in AWS S3 using the AWS S3 API involves copying the object to a new location with the desired name and then deleting the original object. For more information, see https://docs.aws.amazon.com/AmazonS3/latest/API/API_CopyObject.html#API_CopyObject_Examples
var success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var rest = new CkRest();
// Connect to the Amazon AWS REST server in the desired region.
var bTls = true;
var port = 443;
var bAutoReconnect = true;

// Provide AWS credentials.
var authAws = new CkAuthAws();

// This particular bucket is in the Oregon region, as opposed to the US Standard,
// therefore the Region must be set appropriately.
// Also note that we connected to "s3-us-west-2.amazonaws.com".
authAws.Region = "us-west-2";
rest.SetAuthAws(authAws);
// Set the bucket name via the HOST header.
// In this case, the bucket name is "chilkat.qa".
// Note that the Host header should use "bucketName.s3.amazonaws.com", not "bucketName.s3-us-west-2.amazonaws.com"
rest.Host = "chilkat.qa.s3.amazonaws.com";
// Copy /images/sea_creatures/starfish.jpg to /images/sea_creatures/starfish3.jpg
// Notice here that the x-amz-copy-source includes the bucket in the source path,
// but the target path passed to FullRequestNoBody does NOT contain the bucket (because the bucket
// was already specified in the Host header).

// with an XML body.
