HTTPOnly and Secure Cookie Attribute

Hello,

I wanted to set the httponly and secure cookie attribute. Added

proxy_cookie_path / "/; HTTPOnly; Secure";

to an <name>.conf in /etc/nginx/conf.de/ as this should be included by the ngnix.conf which says:

http { include /etc/nginx/conf.d/*.conf; }

However, as I have a look in the request header with crome developer tools I only read lines from dune but do not finde the two attributes there. What do I do wrong? I am a bit confused from the content of /etc/nginx in openmediavault...
