Disabling cache on remote_addr

[Davide D'Amico]

Hi,
I'm using this stanza to configure caching on jpeg|css|gif files:

  location ~ \.(gif|jpg|png|css)$ {
    proxy_pass http://1_2_4_backend;
    proxy_cache STANZA00;
    proxy_cache_valid 200 10m;
    proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504;
  }

But I have to disable caching depending on remote_addr.

How could I accomplish this?

Thanks in advance,
d.
