How to load html cache from external nginx server?

Question

Nginx

Friends, for some time now I have been trying to find a solution for loading the cache through the domain. I use the Super Cache plugin in WordPress.
Now the files are loaded by the line from the main domain example.tdl :

# Если кеша нет, тогда отправляемся к WordPress, чтобы он его нам создал
  location / {
        index index.php index.html;
        try_files /wp-content/cache/supercache/${http_host}${cache_uri}index.html /wp-content/cache/supercache/${http_host}${cache_uri}index-https.html $uri $uri/ /index.php?$args ;
  }

But here's the moment. I need it to load from the cdn.example.tdl domain and use the domain at the beginning of the "/wp-content/cache/supercache/" line. Is it possible to do this somehow. Perhaps this should not be done with the location function. I'm in nginx full 0.

Answer 1

server {
   server_name cdn.example.tdl;
   # тут проверяешь наличие кэша, если файла нет, то сработает @redirect
   location / {
        try_files /wp-content/cache/supercache/${http_host}${request_uri}index.html @redirect;
   }
   
    # перенаправление на основной домен
    location @redirect {
        return 301 http://example.tdl$request_uri;
    }
}
