Keyword Blocking URL Checking

The NBG-417N checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking.

The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/ pressroom.php, the domain name is www.zyxel.com.tw.

The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.

Since the NBG-417N checks the URL’s domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the NBG-417N would find “tw” in the domain name (www.zyxel.com.tw). It would also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.
