code: @Override
    public void channelActive(final ChannelHandlerContext ctx) throws Exception {
      String terseUri = "/pools/default/bs/" + bucket;
      FullHttpRequest request = new DefaultFullHttpRequest(HttpVersion.HTTP_1_1, HttpMethod.GET, terseUri);
      request.headers().add(HttpHeaders.Names.ACCEPT, "application/json");
      addHttpBasicAuth(ctx, request);
      ctx.writeAndFlush(request);
    }
docs: Once the channel is active, start to send the HTTP request to begin chunking.
