Help needed: I am trying to use HAProxy to deny access from internet to a specific URL

Hi all
I am a beginner level HAProxy user and I am trying to use HA proxy to deny access to an inside web page from outside of my firewall.
I am sharing photos with my family using an internal server
The pictures are at
This is natted and exposed to Internet
If the user tries to use http://public_ip:8080/ the request is redirected to http(s)://public_ip:8080/cgi-bin/
This last URL (with cgi-bin) is what I am trying to restrict access to or better make impossible to use.

Here is my config file, please if you could tell me what I am doing wrong, no matter what I do the URL http://public_ip:8080/cgi-bin/ is still available
