Keyword Blocking URL Checking

The NBG-419N 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-419N 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-419N 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”.
