Normal nginx approach is to configure distinct server{} and location{} blocks for different content, with appropriate cache validity times. For example: server { listen 80; server_name foo.example.com; location / { proxy_pass http://backend; proxy_cache one; proxy_cache_valid 200 5m; } location /static/ { proxy_pass http://backend; proxy_cache one; proxy_cache_valid 200 24h; } } Note well that by default nginx respects what is returned by the backend in various response headers, and proxy_cache_valid time only applies if there are no explicit cache validity time set, see http://nginx.org/r/proxy_ignore_headers. -- Maxim Dounin http://mdounin.ru/ _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
