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_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cache_valid 200 301 302 304 1m;
proxy_cache_valid 404 502 503 1m;
proxy_cache_methods GET HEAD POST;
client_max_body_size 255M;
location / {
limit_conn perip 80;
limit_req zone=hostreqlimit burst=1100 nodelay;
default_type text/html;
proxy_pass http://127.0.0.1:81;
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_buffers 256 4k;
proxy_max_temp_file_size 0k;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header realip $remote_addr;
proxy_ignore_headers "Cache-Control" "Expires";
proxy_cache memproxy;
add_header X-Cache-Status $upstream_cache_status;
}
Однако каждую минуту на бэкенд (который proxy_pass http://127.0.0.1:81;)
поступает вместо одного запроса для главной страницы, штук 50-300. В чем
может быть проблема?
