Description
Controls whether SpeculationRules prefetch requests are allowed for
ServiceWorker-controlled URLs.
With Microsoft Edge version 138,
prefetch requests to ServiceWorker-controlled URLs are allowed by default when
the PrefetchServiceWorker feature is enabled.
If this policy is enabled or not configured, that default behavior is used.
To restore the legacy behavior from versions before 138, where prefetch requests
to ServiceWorker-controlled URLs were blocked, set this policy to disabled.
This policy is intended to be temporary and will be removed in the future.
