ProxySG Content Policy Language Guide
250
define category Category definitions are used to extend vendor content categories or to create your own. The
category_name definition can be used anywhere a content filter category name would normally be
used, including in category= tests.
Definitions can include other definitions to create a hierarchy. For example, sports could include
football by including category=football in the definition for sports. A defined category can have at
most one parent category (multiple inheritance is not allowed).
Multiple definitions using the same category_name are coalesced together.
When policy tests a request URL to determine if it is in one of the categories specified by a trigger, all
sub-categories are also checked (see Examples).
Syntax
define category category_name
urlpaths
end [category_name]
where:
•category_name—If category_name matches the name of an existing category from the
configured content filtering service, this is used to extend the coverage of that category; otherwise
it defines a new user defined category. category_name can be used anywhere a content filter
category name would normally be used, including in category= tests.
•urlpaths—A list of domain suffix or path prefix expressions, as used in the url.domain=
condition.You only need to specify a partial URL:
❐Hosts and subdomains within the domain you specify are automatically included.
❐If you specify a path, all paths with that prefix will be included (if you specify no path, the
entire site is included).
Layer and Transaction Notes

Examples
The following example illustrates some of the variations allowed in a category definition:
define category Grand_Canyon
kaibab.org
www2.nature.nps.gov/ard/parks/grca/
nps.gov/grca/
grandcanyon.org
end
The following definitions define the categories sports and football, and make football a sub-category
of sports:
define category sports
sports.com
