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.
