This is legacy kernel JS ( /etc/cloudsettings.kernel.js/libs/settings/cloudsettings/legacy/contexthub) which is pointing to /apps/settings/cloudsettings/legacy/contexthub.kernel.js.
So better you can add rewrite rule in Dispatcher vhosts.d for above one along with whitelisting allow for /apps folder in dispatcher.d file to cache this file on Dispatcher side.
