Reads content from the stream and sends it to the server.
public fun setSendStream(sendStream: InputStream?)
This method reads content from the stream and sends it to the server. The stream should be open and normally set to position 0. The call will return only after the end of stream has been reached. The component will automatically close this stream if CloseStreamAfterTransfer is set to true (default). The content will be read starting at the current position in the stream.
