ATS will only cache full object requests. It never caches range requests. If an object has been cached in whole, then subsequent range requests will be served from that cached object. There is a team somewhere working on caching partial objects but I don't know what they current state is. If a range request is received by ATS and the object is not in the cache the request will simply be forwarded to the origin server and no caching will occur.
