报价:

.Net的印象是，无论如何它已经发送了数据，但是服务器发送了Connection:关闭，因此它显示错误而不重新发送请求.

.Net is under impression that it has anyway already sent the data but server sent Connection : Close so it shows error without resending(sic) the request.

So the solution for the above that worked for me was

System.Net.ServicePointManager.Expect100Continue = False

如果要查看闯入者之间的流量，请使用Wireshark或类似工具侦听HTTP交换.

If you want to see the traffic between the interlopers, snoop the HTTP exchange with Wireshark or a similar tool.
