Categorize each page regardless of HTTP rules
If this option is enabled, Kerio Web Filter categorization will be applied to any web pages
(i.e. to all HTTP requests processed by the HTTP protocol inspector).
Categorization of all pages is necessary for statistics of the categories of visited web
pages (see chapter 21 ). If you do not intend to keep these statistics, it is recommended
disable this option (categorization of all web pages might be demanding and it might
decrease WinRoute performance).
Servers (Web sites) not to be rated by the module can be specified in Kerio Web Filter white list .
Use the Add button to open a dialog where a new item (server or a Web page) can be added.
Server
Use the Server item to specify web sites not to be classified by the Kerio Web Filter . The
following items can be specified:
• server name (e.g. www.kerio.com ). Server name represents any URL at a corre-
sponding server,
• address of a particular webpage without protocol specification ( http:// ) — e.g.
www.kerio.com/index.html ,
• URL using wildcard matching (e.g.
*.ker?o.*
). An asterisk stands for any num-
ber of characters (even zero), a
*.ker?o.*
question-mark represents just one
symbol.

Kerio Web Filter use
To enable classification of Websites by the Kerio Web Filter module, this module must be
running and all corresponding parameters must be set.
Whenever WinRoute processes a URL rule that requires classification of pages, the Kerio Web
Filter module is activated. The usage will be better understood through the following example
that describes a rule denying all users to access pages containing job offers.
On the URL Rules tab in Configuration
→
Content Filtering
→
HTTP Rules , define a rule by using
image 12.7 as guidance:
The is rated by Kerio Web Filter rating system is considered the key parameter. The URL of each
opened page will be rated by the ISS OrangeWeb Filter module. Access to each page matching
with a rating category included in the database will be denied.
Use the Select Rating button to open a dialog where Kerio Web Filter rating categories can be
chosen. Select the Job Search / Job offers rating category (pages including job offers).
