Re: Where to specify gzip and buffer parameters on nginx proxy and nginx web server?

Within location you forgot something like this:

fastcgi_cache_key $scheme$host$request_method$request_uri;
fastcgi_cache_valid 200 302 304 30m;
fastcgi_cache_valid 301 1h;
fastcgi_cache_valid any 5m;
fastcgi_cache_use_stale error timeout invalid_header updating http_500;
