Policy overview

Key metadata and intent for this policy.

Category
Microsoft Edge
Supported on
Microsoft Edge version 140, Windows 7 or later

Supported OS tags: Windows7

This policy controls whether Microsoft Edge enables the ServiceWorkerAutoPreload feature. If you enable or don't configure this policy, Microsoft Edge can initiate the main resource network request concurrently with the Service Worker bootstrap process. This can improve performance in scenarios where the Service Worker isn't already running. If you disable this policy, Microsoft Edge will wait to dispatch the navigation request until after the Service Worker starts. This is a temporary policy and is removed in version 154 of Microsoft Edge. For more information on the feature, see https://github.com/WICG/service-worker-auto-preload.
