I have the following test installation on HA-Proxy version 2.2.4-1ppa1~bionic 2020/10/02:
timeout connect 5000
timeout client 50000
timeout server 50000
timeout http-keep-alive 2m
server iris 10.220.38.3:8001
I create http1.1 request. Request from client consists header ‘Connection: keep-alive’, but request from Haproxy to backend without this header.
Is this a bug or feature? It works as expected on 1.9. How can I solve this problem?
