How do I set Keep Alive

Hello, I am new to nginx and Speedgrade suggest I enable keepalive to
enhance performance of my website(s).

I’ve read*1 that enabling this is also a risk. What is the best
practise?

If your backend is sensitive to keepalive traffic (mine are), then my
advice is to enable keepalives as far into your stack as you can.

i.e. I have nginx fronting haproxy and varnish, I enable keepalives to
both
haproxy and varnish add have them add a “connection: close” header to
their
backend requests. That keeps the backends happy but still lets the
frontends take advantage of connection reuse.
