Chapter 3: Condition Reference
59
category=
Tests the content categories of the requested URL as assigned by policy definitions or an installed
content filter database.
A URL that is not categorized is assigned the category none.
If a content filter provider is selected in configuration, but an error occurs in determining the category,
the URL is assigned the category
unavailable (in addition to any categories assigned directly by
policy). This can be the result of either a missing database or license expiry. An additional category of
unlicensed is assigned in the latter case.
A URL may have been assigned a list of categories. The
category= trigger is true if it matches any of
the categories assigned to the URL.
You cannot use
category= to test the category assigned by off-box content filtering services. These
services have their own policy that must be managed separately.
Notes:
•If
category=unlicensed is true, category=unavailable is true.
•
category=unavailable replaces the deprecated category.unavailable=yes syntax.
•
category=(category_list) exception(content_filter_denied) replaces the deprecated
block_category(category_list)
syntax.
Syntax
category={ none|unlicensed|unavailable|category_name1, category_name2, ...}
where category_name1, category_name2, ... represent category names defined by policy or the
selected content filter provider. The list of currently valid category names is available both through the
Management Console and CLI.
