It occurs to me that I don't believe I've seen any discussion of the Unexpected Consequence of pervasive HTTPS replacing HTTP for unauthenticated sessions, like non-logged-in users browsing sites like Wikipedia. That traffic's not cacheable, is it? Proxy caches on services like mobile 3/4G, or smaller ISPs, or larger corporations can't cache it, I wouldn't think, which means both that they will see traffic increases, and that the end sites will as well. Has this been discussed and I missed it? Do I improperly understand transparent caching? Or is this just a bomb waiting to go off? I assume that Wikipedia themselves are on top of the idea that their in-house reverse-proxies won't be carrying that traffic (though I don't actually know what their architecture looks like anymore), but..
