This feature enables the use of dictionary-specific content encodings in the Accept-Encoding request header ("sbr" and "zst-d") when dictionaries are available for use. Setting the policy to Enabled or leaving it unset means Google Chrome will accept web contents using the compression dictionary transport feature. Setting the policy to Disabled turns off the compression dictionary transport feature.

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.
