Nginx Directory Listing - Restrict by IP Address

[Sathish Kumar]

Hi,

I am doing for location /, in that case how will have to change the below
portion.

location /downloads {
    alias /downloads/;
    autoindex on;
    if ($forbidlisting) {
        rewrite /downloads(.*) /noindex_downloads/$1 last;
    }
}
location /noindex_downloads/ {
    internal;
    alias /downloads/;
}
