Re: proxy_ignore_headers doesn't seem to work

Maxim,

Sorry for the late response.

I'm trying to hide those headers, you can see it in config posted before:

proxy_ignore_headers X-Accel-Expires Expires Cache-Control Set-Cookie;
proxy_cache_valid 200 302 600h;
proxy_cache_valid any 90m;

But as you can see, you can find expire, cache-control headers in proxy repsonse, and also in headers of stored cache files on disk. With values from upstream server, not those set in config.


I'm not sure now those times from my previous response, but whatever i do (delete cached files from disk, restart nginx, wait 10 minutes to expire files cached on disk), nginx is always returning in response cache-control and expire in 600 sec - taking this value from upstream server, not from the config file. Also, file is stored on disk for 600s, after this time i can see in logs that nginx is downloading again file from upstream server. Nginx should cache files for 600h in current config, but i've also tried before other values, like 6h or 6d etc.
