A couple of relevant links: - Google technical note: https://technotes.googlecode.com/git/nextprotoneg.html - IETF draft: http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-02 NPN allows the client to negotiate the session protocol as part of the TLS handshake (ex, "http 1.1", or "spdy/v{1,2,3}"). To support SPDY we need NPN support within OpenSSL core in Ruby. The API is already implemented in OpenSSL 1.0.1+, so it's a matter of adding support in Ruby core.
