RewriteRule in Apache .htaccess is a convenient way to block directory access to a directory in your Apache document root. This can be useful to avoid accidental access to some content in these directories. Here is the config you can use in .htaccess in the desired directory.
<IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^.* - [R=404,L] </IfModule>
Note that you don’t need to restart apache after .htaccess changes. R=404 will set the HTTP status code to 404. L is used to stop processing more mod_rewrite rules.
