The best way would be to create a location for this particular page:

  location /industry/category/cars {
      ...
  }

http://nginx.org/en/docs/http/ngx_http_core_module.html#location


also, you can utilize the map directive functionality, e.g:

  map $uri $is_cached_uri {
      default                  1;
      /industry/category/cars  0;
  }

  proxy_cache_bypass $is_cached_uri;
