2261	A case of Connection: keep-alive, Upgrade	xinyanglbeijing@…		"nginx -v

kernel
Linux ubuntu1804-dev-server-xinyang 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Description:
This case happened when I used firefox to get a websocket connection.
If I uses chrome that works well.

Below is the http traffic.
