Configuring URL filtering
This section describes how to use, configure and monitor URL filtering. For more information about
the URL Filtering feature, see "URL filtering" on page 20.
How to Use URL Filtering
To use URL filtering, you can either use:
 a blacklist provided by Kaspersky
 custom lists (black/white)
 a combination of custom and Kaspersky lists.
Creating custom lists
A custom list is an ASCII formatted text file containing zero or more single-line pattern matches.
For example, the content of a text file named blacklist-example.txt, consisting of three patterns to
match, (listed line-by-line) could look like this:
URL pattern matches listed within the text file may take two forms:
 either a base domain, which will match all content of that domain, and all content of sub-domains:
 or a wild-card match, where an asterisk will match zero or more characters in a URL:
Once this list is available to the system (stored in Flash, USB, or on an SD card), the configuration to
enable URL filtering is straight forward, as described below in the section "Configuring URL
filtering" on page 45.
