I have two servers, an NGINX balancer that receives connections from Cloudflare and two application apache servers where these connections are forwarded.
[Cloudflare] → [NGINX] → [Apache]
My apache server will only be connected through NGINX, and NGINX only accepts HTTP/HTTPs connections coming from Cloudflare.
By default NGINX always sends the user to the same Apache server he visited the first time.
I already have Apache configured with Keep Alive.
Should I also configure NGINX to keep connections alive?
