Buffering helps to optimize performance with slow clients, which can waste proxied server time if the response is passed from NGINX to the client synchronously. A response is stored in the internal buffers and is not sent to the client until the whole response is received. Before using NGINX as a reverse proxy users would need to enter the IP address of my test Kibana server and enter port number (5601) at the end of the address.
