15.4 URL Groups
Note:
1. Generally, protocol inspectors cannot be applied to secured traffic (SSL/TLS). In this case,
Kerio Control “perceives” the traffic as binary data only. This implies that such traffic
cannot be deciphered.
2. Under certain circumstances, appliance of a protocol inspector is not desirable. Therefore,
it is possible to disable a corresponding inspector temporarily. For details, refer to
chapter 7.7.
15.4 URL Groups
URL Groups enable the administrator to define HTTP rules easily (see chapter 13.2). For
example, to disable access to a group of web pages, you can simply define a URL group and
assign permissions to the URL group, rather than defining permissions to each individual URL
rule. A URL group rule is processed significantly faster than a greater number of separate
rules for individual URLs. It is also possible to cascade URL groups.
URL groups can be defined in Configuration → Definitions → URL Groups.

URL Groups
The default Kerio Control installation already includes predefined URL groups:
• Ads/Banners — common URLs of pages that contain advertisements, banners, etc.
• Search engines — top Internet search engines.
• Windows Updates — URL of pages requested for automatic updates of Windows.
