For keepalive in upstream proxy you shoud use upstream configuration block
and configure keepalive in it:
upstream backend {
zone backend 1m;
server your-server.com;
keepalive 128;
}
server {
listen 8080;
location / {
proxy_cache proxy-cache;
proxy_cache_valid 200 302 301 30m;
proxy_cache_valid any 1m;
proxy_cache_key $scheme://$http_host$request_uri;
proxy_pass $scheme://backend$request_uri;
proxy_http_version 1.1;
proxy_set_header Connection "";
}
}
