SSL: Next Protocol Negotiation extension support. Not only this is useful for the upcoming SPDY support, but it can also help to improve HTTPS performance by enabling TLS False Start in Chrome/Chromium browsers [1]. So, we always enable NPN for HTTPS if it is supported by OpenSSL. [1] http://www.imperialviolet.org/2012/04/11/falsestart.html
