is it possible for NGINX to have a pool of N open connections to backend? -

-

trying use nginx reverse proxy, , have constant number of open connections backend (upstream) open @ times.

is possible nginx (maybe haproxy..?) ??

running on ubuntu if makes difference

something can done haproxy. end result there no more n concurrent connections backend server + open connections shared between requests coming different clients.

backend app   http-reuse safe   server server1 127.0.0.1:8080 maxconn 32   server server2 127.0.0.2:8080 maxconn 32

the example shows 2 servers, haproxy not open more 32 connection each server, , each connection can shared between several clients whenever can done safely.
