Имеется конструкция для кеширования всего сайта:
proxy_cache_path /var/cache/nginx/cache levels=2:2
keys_zone=memproxy:10m max_size=3072m inactive=3h;
proxy_temp_path /var/cache/nginx/proxy;
proxy_cache_key "$scheme://$host$request_uri";
proxy_redirect off;
proxy_set_heade
Имеется аналогичная проблема:
