See also support for the SPDY protocol, precursor of HTTP2.

  1. Partial support in IE11 refers to being limited to Windows 10.

  2. Only supports HTTP2 over TLS (https)

  3. Partial support in Safari refers to being limited to OSX 10.11+

  4. Only supports HTTP2 if servers support protocol negotiation via ALPN
