test cache control contain s-maxage

Hi,
i want to cache response only if Cache-Control contain "s-maxage" i add this map:

map $upstream_http_cache_control $no_cache {
     default 1;
     "~*s-maxage" 0;

}

Code (ApacheConf):

in the location :

location ~* "\.(html)$" {
               proxy_pass  http://prod;
          proxy_set_header Host $http_host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;

               include /etc/nginx/conf.d/shared/cache_html.conf;
}

Code (ApacheConf):

in the cache conf:

proxy_cache_methods GET ;
proxy_cache_valid any 48h;
proxy_no_cache       $no_cache;

Code (ApacheConf):

but this not work...
