First of all, there is absolutely no change in the functionality of Cache Cleaner (CC).  All that has really changed here is that Cache Cleaner has been integrated directly into Host Checker (HC).  Now whenever you create any HC policy, you will simply see that  CC options are available under that settings.  This makes things easier to administer, reduces the number of executables that are pushed to the client machine, provides better support for NC and WSAM launchers, and offers integrated logging through NC.
