URL Filter
URL (Uniform Resource Locator
– e.g. an address in the form of
http://www.example.com ) filter rules allow you to prevent users on your network from
accessing particular websites from their URL. There are no pre-defined URL filter rules;
you can add filter rules to meet your requirements.
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather
than having to specify a complete URL (e.g. to block any image called
“advertisement.gif”). When enabled, your specified keywords list is checked to see if any
keywords are present in URLs accessed to determine if the connection attempt should
be blocked. Note that the URL filter blocks web browser (HTTP) connection attempts
using port 80 only.
For example, the URL http://www.abc.com/abcde.html would be dropped since the
keyword “abcde” occurs in the URL.
