Nginx close uplink after request

Question

I need to maintain communication between nginx and upstream nodejs.

Compiled and installed nginx 1.2.0

my configuration file:

upstream backend { ip_hash; server dev:3001; server dev:3002; server dev:3003; server dev:3004; keepalive 128; } server { listen 9000; server_name dev; location / { proxy_pass http://backend; error_page 404 = 404.png; } } 

My program (dev: 3001 - 3004) detects that the connection was closed by nginx after the response.

Answer 1

The documentation states that for http keepalive you must also set proxy_http_version 1.1; and proxy_set_header Connection "";
