The |/connections/| parameter should be set low enough(??) to allow upstream servers to process additional new incoming connections as well. I am very confused about the keepalive <http://nginx.org/en/docs/http/ngx_http_upstream_module.html#keepalive> connections in the ngx_http_upstream_module, can somebody tell me how to determine the keepalive connections in http protocol ? just likby mozatkey - Nginx Mailing List - English
