Restrict Background Fetch API when called from a Service Worker
Supported on: Microsoft Edge version 149, Windows 7 or later
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: RestrictBackgroundFetchFromServiceWorkerEnabled
Enabled: RestrictBackgroundFetchFromServiceWorkerEnabled = 1
Disabled: RestrictBackgroundFetchFromServiceWorkerEnabled = 0
Description
This policy controls whether background fetch requests from Service Workers are restricted. If a feature that downloads files in the background is affected, this policy may be relevant. If you enable this policy or don't configure it, the restriction is active, and background fetch requests from Service Worker contexts may be blocked. If you disable this policy, the restriction is bypassed, allowing Service Workers to make background fetch requests. This policy is temporary and will be removed after Microsoft Edge version 152.
