Hi.

Frontend log:
* * [09/Feb/2016:12:58:14 +0000] "GET /hls.ts HTTP/1.1" 200 MISS "123.123.123.123" 1651956 "-" "HLS Client" "15.711" "-" "-/-" "1/196861693" "0.021" "13.275" "200" RU

Backend log:
* * [09/Feb/2016:12:57:59 +0000] "GET /hls.ts HTTP/1.1" 200 HIT "-" 1651956 "-" "HLS Client" "0.388" "-" "-/-" "84/238345969" "-" "-" "-" RU

So there is the question: why it's different times in frontend and backend logs? I mean (13.275) upstream_response_time from frontend and (0.388) request_time from the backend? It's must be the same.
