I configured nginx as reverse proxy to an application server java disabling the proxy buffering: proxy_buffering off; proxy_request_buffering off; I noticed that when a client makes a request to the java server (e.g. download a file), nginx buffered the response in memory (around 3Mb). I would like to configure nginx so as not buffered the response (or at least minimize this buffer) itby webdel - Nginx Mailing List - English
