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;
