Clear a REST Response Body Stream Destination

See more REST Examples

Demonstrates Rest.ClearResponseBodyStream, which removes a response-stream destination previously configured with SetResponseBodyStream.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.
