Selection of Kerio Web Filter categories
Note:
1.
You can define multiple URL rules that will use the
Kerio Web Filter
rating technology.
Multiple categories may be used for each rule.
2.
We recommend you to unlock rules that use the
Kerio Web Filter
rating system (the
Users
can Unlock this rule
option in the
Advanced
tab). This option will allow users to unlock
pages blocked for incorrect classification. All unlock queries are logged into the
Filter
log
— here you can monitor whether unlock queries were appropriate or not.
12.4 Web content filtering by word occurrence
WinRoute
can also filter Web pages that include undesirable words.
This is the filtering principle: Denied words are matched with values, called weight (repre-
sented by a whole positive integer). Weights of these words contained in a required page are
summed (weight of each word is counted only once regardless of how many times the word is
included in the page). If the total weight exceeds the defined limit (so called threshold value),
the page is blocked.
