Yes, and yes. > I need to offload the compression work from backend to the proxy Why?

The hard part is figuring out when and how to do it; ideally, we should compress a document only if and only if we get a request from a client that supports compression, and when we do, we should cache it with the same ttl as the original object. I imagine that some of the mechanisms that were introduced to support Vary can also be used to support native compression.
