(VB.NET) Explaining the Rest ClearResponseBodyStream Method

See more Azure Cloud Storage Examples

The ClearResponseBodyStream method would be needed if your applicaiton called SetResponseBodyStream to send the response to a stream for one request, but then wants to subsequently do something else. The application must call ClearResponseBodyStream to no longer send responses to the stream.
