proxy_ignore_headers when not using cache

[Jérôme Loyet]

Hi igor,

how the directive proxy_ignore_headers is used when the cache is not
set for a location ? for exemple:

http {
  ...
  proxy_cache_path /LIBRE/nginx/cache levels=1:2 keys_zone=one:32m
inactive=1d max_size=4g;
  proxy_ignore_headers Expires Cache-Control;
  server {
    ...
    location / {
      proxy_pass http://127.0.0.1:8080
      proxy_cache one;
      proxy_cache_valid 5m;
    }
    location /not_cached {
      proxy_pass http://127.0.0.1:8080
    }
  }
}

For every pages (exept the ones catched by the /not_cached location),
pages are cached for 5 minutes whatever the headers Expires and
Cache-Control say.

But for the /not_cached pages, what does the proxy_ignore_headers do ?
As far as I understand it, it should do nothing. Am I right ?

Thx
