Hi
I read here that keepalives to backend can be enabled with the upstream 
module 
(http://nginx.org/en/docs/http/ngx_http_upstream_module.html#keepalive)
But can they be used without defining an upstream block? Just a simple 
proxy_pass as the backend is a variable in my case: 'proxy_pass $proxy_to;'

Many thanks
