Configure Digital Asset Management with a CDN

If you are using a content delivery network (CDN) such as Akamai, using Vary: Origin may prevent you from caching content. To bypass this limitation, your CDN configuration must strip the Vary header on the way in, to reinstate your ability to cache content. On the way out, you can append the Origin parameter to the Vary header when serving a response using 'Modify Outgoing Response Header'.
