Policy for caching YouTube content
The volume of YouTube traffic on your network grows continually and you need the ability to efficiently cache YouTube content on ProxySG appliances. For efficient WAN/Internet bandwidth usage, you require a policy configuration ensuring that after a video is cached on the ProxySG appliance, all subsequent requests for the same video are served from the cache.
Blue Coat has provided a custom policy (attached to this KB article) that allows the appliance to effectively cache YouTube content to optimize bandwidth savings and user experience.
Important: Final policy update for SGOS 5.x and 6.x was released on September 24, 2013; if you run SGOS 5.x or 6.x, you can update to the attached policy. Policy for 4.x was not updated and has been deprecated. Both policies attached to this article are the final versions and will no longer be maintained from this point onward. To continue to stay up-to-date with policy for caching YouTube content, upgrade to SGOS 6.5.2.x or later and subscribe to the CachePulse service. For more information on the CachePulse service, refer to the SGOS 6.5.2.x Administration Guide.
