Sets the stream to be uploaded to the server.
Public Sub SetUploadStream(ByVal UploadStream As System.IO.Stream)
If an upload stream is set before data is to be uploaded to the server, the content of the stream will be read by the component and uploaded to the server. The stream should be open and normally set to position 0.
The component will automatically close this stream if CloseStreamAfterTransfer is true (default). If the stream is closed, you will need to call SetUploadStream again before calling the PutResource/PostToResource again.
The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.
