Cisco Cisco Web Security Appliance S170 사용자 가이드

An uncategorized URL is a URL that does not match any pre-defined URL 
category or included custom URL category. 

When determining policy group membership, a custom URL category is 
considered included only when it is selected for policy group membership.

All transactions resulting in unmatched categories are reported on the Monitor > 
URL Categories page as “Uncategorized URLs.” A large number of uncategorized 
URLs are generated from requests to web sites within the internal network. 
Because this type of internal transaction can falsely inflate reporting data and 
misrepresent the efficacy of the URL filtering engine, Cisco recommends using 
custom URL categories to group internal URLs and allow all requests to internal 
web sites. This decreases the number of web transactions reported as 
“Uncategorized URLs” and instead reports internal transactions as part of “URL 
Filtering Bypassed” statistics.

When the URL filtering engine matches a URL category to the URL in a client 
request, it first evaluates the URL against the custom URL categories included in 
the policy group. If the URL in the request does not match an included custom 
category, the URL filtering engine compares it to the predefined URL categories. 
If the URL does not match any included custom or predefined URL categories, 
the request is uncategorized. 

When determining policy group membership, a custom URL category is 
considered included only when it is selected for policy group membership.
