Keyword Blocking URL Checking
The NBG4604 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 NBG4604 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 NBG4604 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”.
