Communication between clients and backends should be bi-directional
Make SPDY the default, embrace dynamic topologies
The first step towards these goals is to recognize that translating SPDY to HTTP is a convenient path in the short term, but exactly the wrong path in the long term. SPDY offers multiplexing, …
