Classify URLs for Policy Application
Overview of Categorizing URL Transactions
Using policy groups, you can create secure policies that control access to web sites containing 
questionable content. The sites that are blocked, allowed, or decrypted depend on the categories you 
select when setting up category blocking for each policy group. To control user access based on a URL 
category, you must enable Cisco Web Usage Controls. This is a multi-layered URL filtering engine that 
uses domain prefixes and keyword analysis to categorize URLs. 
You can use URL categories when performing the following tasks:
Option
Method
Define policy group membership
Control access to HTTP, HTTPS, and FTP 
requests
Create user defined custom URL categories that 
specify specific hostnames and IP addresses
