Add the following directives to  ssl.conf or default.conf

By using “nginx_cookie_flag_module” Module

A Nginx module called nginx_cookie_flag by Anton Saraykin let you quickly set cookie flag as HTTPOnly and Secure in Set-Cookie HTTP response header.

Add this flag to your configure directives:

Once Nginx is built with the above module, you can add the following line either in location or server directive in respective configuration file

Restart Nginx to verify the results.
