Google searches brought me here, so I decided that today I would publish what I found in apache docs . I'm not sure which apache versions are available, but search your version to check.
Now you can just use Require local . I would recommend placing .htaccess in the folder from which you want to restrict access, only with this line. However, if you must do this in the root directory, then this is what it will be:
<Directory "www/html/INC"> Require local </Directory>
