licensing policy, read chapter 44 .
2. The firewall’s traffic rules must not block access to ISS OrangeWeb Filter’s database
servers. If, for any reason, access from the firewall to the Internet is restricted, it is
necessary to allow access to the COFS service (6000/TCP).
3. If the Internet connection is provided by a dial-up, it is not recommended to use ISS
OrangeWeb Filter.
Upon startup of the WinRoute Engine, access to the database server is checked (this
process is called activation). This activation is refreshed regularly.
If the line is hung up while the activation is being started and refreshed, the activation is
not started and the ISS OrangeWeb Filter module will not work. In addition, communica-
tion with the database server significantly increases the response time for connection to
such web pages classification of which is not saved in the local cache.
ISS OrangeWeb Filter configuration
The ISS OrangeWeb Filter module can be set and configured through the ISS OrangeWeb Filter
tab in Configuration → Content Filtering → HTTP Policy.
Enable ISS OrangeWeb Filter
use this option to enable/disable the ISS OrangeWeb Filter module for classification of
websites.
If ISS OrangeWeb Filter is disabled:
• the other options in the ISS OrangeWeb Filter tab are not available,
• all URL rules which use the ISS OrangeWeb Filter classification are disabled (for
details, refer to chapter 12.4 ).
Categorize each page regardless of HTTP rules
If this option is enabled, ISS OrangeWeb 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 eb specified in ISS OrangeWeb Filter
white list. Use the Add button to open a dialog where a new item (server or a Web page) can be
added.
