Description
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.

Yaroslav, please take a look. Something like a "Caching and storing responses to disk only only works if buffering is enabled" note should improve things (see proxy_limit_rate and proxy_max_temp_file_size for some related text).
BTW I think it's worth site here comments from stackoverflow:
Made my day. I've spent 3 days! To figure out what the wrong with our config. Big, great thank you @Overbryd , from bottom of my heart. – dr.dimitru Apr 3 '16 at 13:37
@Overbryd gj! was fighting nginx for 2 days, and your answers is freaking awesome! – Bubonic Pestilence Dec 7 '16 at 10:47
wth - this is not mentioned in ANY caching example on the web that I've found after 3 hours of searching! – HDave Dec 29 '16 at 5:05
