GPEdit: Internet Cache Cleanup?

It's been awhile since I've changed my network's group policy... Though I remember seeing a policy, I'm not sure where it is now. I would like to clear the IE cache upon logout. Any ideas?

*looks around for Inaris*

I've got this:

Clear cache on reboot

I searched thru group policy editor and didnt see that setting, maybe I missed it.

Thanks. The script works, but is there any part of the script that I can delete to remove the "cancel" option?
