Can't make nginx to cache

[Mirosław Jaworski]

Hi

Hello for the first time.

Intended config: nginx as caching reverse proxy. 

nginx version: 0.7.61

Direct connect to backend:

$ telnet 192.168.10.18 80
Trying 192.168.10.18...
Connected to 192.168.10.18.

nginx config:
----------------------------------------------------------------------
worker_processes  4;

events {
    worker_connections  2048;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    server_tokens off;

    client_body_temp_path  /opt/nginx/client_temp 1 2;
    proxy_temp_path        /opt/nginx/proxy_temp 1 2;
    fastcgi_temp_path      /opt/nginx/fastcgi_temp 1 2;

    proxy_cache_path       /opt/nginx/cache/A.B.C.D levels=1:2
keys_zone=one:10m;

    log_format  main  '$remote_addr - $remote_user [$time_local]
"$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    sendfile        on;

    keepalive_timeout  65;
    server {
        listen       A.B.C.D;
        server_name  localhost;
        access_log  /var/log/nginx/A.B.C.D.access.log  main;
        location / {
            proxy_pass         http://192.168.10.18:80/;
            proxy_redirect     off;

            proxy_cache        one;

            proxy_pass_header  Set-Cookie;

            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For
$proxy_add_x_forwarded_for;
        }
    }

}
----------------------------------------------------------------------

I don't see anything preventing caching, but cache ( path given by
proxy_cache_path ) remains empty :|

$ ls -al  /opt/nginx/cache/A.B.C.D
total 4
drwxr-xr-x  2 www  www  512 Jul 21 12:13 .
drwxr-xr-x  9 www  www  512 Jul 21 12:13 ..

Should i do something more?

Regards

MJ
