This policy setting determines whether Internet Explorer uses the SPDY/3 network protocol. SPDY/3 works with HTTP requests to optimize the latency of network requests through compression, multiplexing and prioritization. If you enable this policy setting, Internet Explorer uses the SPDY/3 network protocol. If you disable this policy setting, Internet Explorer won't use the SPDY/3 network protocol. If you don't configure this policy setting, users can turn this behavior on or off, using Internet Explorer Advanced Internet Options settings. The default is on.
