[question] Can we use ngx_socket_connect() to an upstream?

[joanhey]

So we will have a pool, and extra options to the connection for free.

We can do it if we set a route in the config, that point to the upstream, and we point the connection to that route.
But can we do it directly, without the route ?

Sure, php_keepalive directive can be set upstream connection pool size.
