I want to hide the google spreadsheets target link using proxy_pass, and only allow access to my domain from specific IPs.
I would also like to hide the full link path for example instead of https://mydomain/spreadsheets/d/1Uv4qm0kps******XkXnTJMLNeqJmgM/edit?usp=sharing

https://mydomain/file1/

I’ve tried different options, here’s one of them:

      location /spreadsheets {
        proxy_ssl_server_name on;
        proxy_ssl_name "docs.google.com";
        proxy_set_header Referer "https://docs.google.com/";
        proxy_pass https://docs.google.com;
        proxy_redirect https://docs.google.com https://$host:$server_port;
        proxy_set_header Accept-Encoding "";
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        sub_filter_once off;
        sub_filter 'https://$proxy_host' 'https://$host:$server_port';
}
