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.

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
