This scenario begins with an employee connecting to the appliance from a public kiosk:
From 12.4.2 onwards, Cache Cleaner functionality is no longer supported in mac or windows platforms.
In this scenario, the appliance finds that the client doesn’t match any of the configured device profiles. There are a couple of ways to handle this sort situation: classify the client into a Quarantine zone, or into the Default zone. In this example, the Quarantine zone Untrusted is used. The only resources a user has access to are those that you have set up: you might, for example, display a customized page with links to Web resources for bringing a system into compliance with your security policies.
If the device’s operating system and browser are not compatible with Cache Cleaner, a message is displayed.
If Cache Cleaner cannot be deployed on the client, the user’s connection request is denied.
See Configuring the Default Zone for information on the setup options for this zone.
