не работает proxy_cache

[Евгений Торопов <jt@xxxxxxxxx>]

Добрый день,

Не могу понять, что мешает кэшированию.

Кэш-конфиг:

proxy_cache_path /opt/local/nginx/cache levels=1:2 keys_zone=sup:32m 
max_size=1024m inactive=1h;

proxy_cache                 sup;
proxy_cache_valid           1h;

proxy_cache_key            "$host$request_uri";
proxy_cache_methods         POST;



Отрывок дебаг лога:
