Easily deny access to multiple folders on nginx?

Hi,

I installed a script yesterday for which I need to disallow web access to some directories.
In Apache, you could do this with an .htaccess file.
Nginx doesn't support .htaccess files. However, I do see this in the nginx conf file:

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}

I though uncommenting these lines would make nginx block all webaccess to folders containing .ht files, but it doesn't.

How do you guys block web access to multiple folders easily?

Thanks
