Abstract
A policy distribution server provides, on a subscription basis, policy updates to effect desired behaviors of network intermediary devices. The policy updates may specify caching policies, and may in some instances, include instructions for data collection by the network intermediary devices. Data collected in accordance with such instructions may be used to inform future policy updates distributed to the network intermediary devices.
