Policy
Disable third-party storage partitioning for specific top-level origins (obsolete)
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 145. This policy lets you set a list of URL patterns that specify top-level origins for which third-party storage partitioning (partitioning of cross-origin iframe storage) should be disabled. If this policy isn't set or a top-level origin doesn't match one of the URL patterns, then the value from 'DefaultThirdPartyStoragePartitioningSetting' (Default setting for third-party storage partitioning) will be used. Note that the patterns you list are treated as origins, not URLs, so you shouldn't specify a path. For detailed information about valid origin patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. This feature has been removed starting in Microsoft Edge version 146. To ensure compatibility, use the requestStorageAccess method instead. For more information, see https://developer.mozilla.org/en-US/docs/Web/API/Document/requestStorageAccess. Example value: www.example.com [*.]example.edu
