DEPRECATED: This policy is deprecated. It is currently supported but will become obsolete in a future release.
This policy is deprecated because it's only intended to be a short-term mechanism to give enterprises more time to update their web content if and when it's found to be incompatible with the change to disallow synchronous XHR requests during page dismissal. It won't work in Microsoft Edge version 88.
This policy lets you specify that a page can send synchronous XHR requests during page dismissal.
If you enable this policy, pages can send synchronous XHR requests during page dismissal.
If you disable this policy or don't configure this policy, pages aren't allowed to send synchronous XHR requests during page dismissal.
