Allow ServiceWorker to dispatch navigation requests without waiting for its startup
Supported versions
- On Windows and macOS since 140 or later
Description
This policy controls whether Microsoft Edge enables the ServiceWorkerAutoPreload feature.
When enabled or not configured, Microsoft Edge may 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 has started.
This is a temporary policy and will be removed in version 144 of Microsoft Edge.
For more information on the feature, see https://github.com/WICG/service-worker-auto-preload.
