REST Download Binary to Memory (Byte Array) (Amazon S3)

See more Amazon S3 (new) Examples

Demonstrates how to make a REST call that returns a binary response body. This example is valid for reasonably small files that fit in memory. The example shows how to download a small JPG from the Amazon S3 service. For larger files, Chilkat provides streaming functionality to stream directly to a file, or to make an asynchronous call where the foreground thread can read the response body stream. PHP ActiveX
