Step 7
To define policy group membership by any of the advanced options, click the link for the advanced 
option and configure the option on the page that appears.
Advanced Option
Description
Protocols
Choose whether or not to define policy group membership by the protocol used 
in the client request. Select the protocols to include.
“All others” means any protocol not listed above this option.
Note
When the HTTPS Proxy is enabled, only Decryption Policies apply to 
HTTPS transactions. You cannot define policy membership by the 
HTTPS protocol for Access, Routing, Outbound Malware Scanning, Data 
Security, or External DLP Policies. 
Proxy Ports
Choose whether or not to define policy group membership by the proxy port used 
to access the Web Proxy. Enter one or more port numbers in the Proxy Ports field. 
Separate multiple ports with commas.
For explicit forward connections, this is the port configured in the browser. For 
transparent connections, this is the same as the destination port. You might want 
to define policy group membership on the proxy port if you have one set of clients 
configured to explicitly forward requests on one port, and another set of clients 
configured to explicitly forward requests on a different port.
Cisco recommends only defining policy group membership by the proxy port 
when the appliance is deployed in explicit forward mode, or when clients 
explicitly forward requests to the appliance. If you define policy group 
membership by the proxy port when client requests are transparently redirected 
to the appliance, some requests might be denied.
Note
If the Identity associated with this policy group defines Identity 
membership by this advanced setting, the setting is not configurable at the 
non-Identity policy group level.
Subnets
Choose whether or not to define policy group membership by subnet or other 
addresses.
You can choose to use the addresses that may be defined with the associated 
Identity, or you can enter specific addresses here. 
Note
If the Identity associated with this policy group defines its membership 
by addresses, then in this policy group you must enter addresses that are 
a subset of the addresses defined in the Identity. Adding addresses in the 
policy group further narrows down the list of transactions that match this 
policy group.
URL Categories
Choose whether or not to define policy group membership by URL categories. 
Select the user defined or predefined URL categories.
Note
If the Identity associated with this policy group defines Identity 
membership by this advanced setting, the setting is not configurable at the 
non-Identity policy group level.
