2048	Document that 'proxy_buffering off' disables caching	peter.volkov@…	Yaroslav Zhuravlev	"If we disable proxy_buffering it will disable caching in nginx. Why is that? I've spent an enormous amount of time to debug this problem while there is no mention of that anywhere in the documentation. Only after I've managed to localize this option (by enabling/disabling random options) I've realised what cases this and found that this was documented in 
https://trac.nginx.org/nginx/ticket/849#comment:1
and
https://stackoverflow.com/questions/9230812/nginx-as-cache-proxy-not-caching-anything

Still, I think such information should be mentioned in the documentation.

TIA.
