Does Adobe Scene7 offer CDN Pre-fetch?
Adobe evaluated prefetch with its CDN provider and jointly agreed it didn't make sense to add it to the offering. It provided little or no return in our use case (and would be an added cost to our customers). Since we cache 90%+ of your images already, there is really nothing to prefetch. In our own daily performance analysis from 27 cities worldwide through 10 ISPs, there is no significant difference in performance for an image pulled from cache or from our origin.
