For example, if the path to be protected is /admin/test.php or /adminabc, set Path to /admin*. Exact match: The path to be entered must match the path to be protected. If the path to be protected is /admin, set Path to /admin. NOTE: The path supports prefix and exact matches only and does not support regular expressions. The path cannot contain two or more consecutive slashes. For example, ///admin. If you enter ///admin, the WAF engine converts /// to /.	/admin/login.php For example, if the URL to be protected is http://www.example.com/admin/login.php, set Path to /admin/login.php.
