Forbid web.config page from the browser as in https://mydomain.com/web.config

[Kaushal Shriyan]

Hi,

I am running the Nginx version: nginx/1.16.1 on CentOS Linux release
7.8.2003 (Core). I am trying to forbid/prevent web.config file to
download it from the browser. When I hit
https://mydomain.com/web.config it is allowing me to download instead of
forbidding the page ( 403 Forbidden). I am sharing the below nginx.conf
file for your reference.

Please let me know if I am missing anything in the Nginx config file.
Thanks in advance and I look forward to hearing from you.
