> Why is this resource asymmetry unavoidable? It seems reasonable that a new protocol could solve it. There's some sense in which a little asymmetry is unavoidable -- a malicious attacker can always just send whatever bytes they want over the wire, and a server on the other end with any practical purpose must at a minimum receive each of those bytes AND perform some operation equivalent to determining if any more work needs to be done. To the extent that any real work or state management needs to be done by the server, the only way to avoid much asymmetry is to use a protocol forcing the client calls to be artificially more expensive before the server will agree to respond.
