Hello,
I'm trying to configure nginx to use proxy_cache_background_update but it
seems like after expiry it still waits for the full roundtrip to the
backend, returning a MISS in X-Cache-Status. What am I MISSing?
I'm using nginx 1.11.12 under ubuntu 14.04 running inside docker, but
hopefully this is too much detail.
location ~ ^/?(\d+/[^/]+)?/?$
{
expires 20s;
proxy_cache app_cache;
proxy_cache_lock on;
proxy_cache_bypass $http_upgrade;
proxy_pass http://172.17.0.2:5000;
proxy_http_version 1.1;
error_log /nginxerror.log debug;
add_header X-Cache-Status $upstream_cache_status;
proxy_cache_use_stale error timeout updating http_500 http_502 http_503
http_504;
proxy_cache_background_update on;
break;
}
NB: This is a duplicate of my so question, I was kindly advised on the nginx
IRC to repost here for better chances, the original question is here:
