[ruby-core:67112] [ruby-trunk - Feature #9390] Support for the ALPN TLS extension

Issue #9390 has been updated by Eric Wong.


 Note: ALPN requires OpenSSL 1.0.2, which is only in beta3 as of now
 (2014/12/24).  I suspect few are willing to use a beta version
 of OpenSSL on their servers.  But I look forward to this feature.

ALPN [1] is a successor [2] to NPN, support for which was added in 2.0.0 [3].

HTTP/2 [4] is using ALPN to negotiate protocol support, and the spec is moving fast -- it'd be great to have ALPN support in one of the upcoming Ruby releases. Current status of ALPN support in various TLS libraries and languages: https://github.com/http2/http2-spec/wiki/ALPN-Status. 

As a side note, for anyone interested, I have an implementation of draft-06 http/2 spec: https://github.com/igrigorik/http-2
