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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X GET \
*   https://your-webapp-hostname:your-webapp-port/v1/media/4b5bf27b-8672-4d55-bc21-d096dc200d0f \
*   -H 'Authorization: Bearer your-auth-token' \
*   -o path/filename

* Use the following online tool to generate HTTP code from a CURL command
* Convert a cURL Command to HTTP Source Code

* Adds the "Authorization: Bearer your-auth-token" header.
loHttp.AuthToken = "your-auth-token"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBdResponseBody = CreateObject('Chilkat.BinData')
