Hi I'm trying to override my default cache-control in my /admin/ folder

location /admin/ {
add_header “Cache-Control: no-cache”;
try_files $uri =404;
access_log off;
}

but everything have a wrong cache-age by running curl -I

curl -I https://domain/admin/index.php

I've tried all the directives from http://nginx.org/en/docs/http/ngx_http_headers_module.html#expires to try overriding this

My goal is to have no-cache on all php files in this subfolder. Any one who could help me?
