Specifies a list of URL patterns for which requests initiated from matching origins are blocked from issuing Local Network Access requests. Network requests initiated from websites served by matching origins are prevented from accessing local device and local network endpoints. For origins not covered by the patterns specified here, the user's personal configuration applies. There are multiple policies that control origins impacting requests to local device and local network endpoints. If an origin matches more than one of the following policies, the policies take precedence in the following order: - LocalNetworkBlockedForUrls - LocalNetworkAllowedForUrls - LoopbackNetworkBlockedForUrls - LoopbackNetworkAllowedForUrls - LocalNetworkAccessBlockedForUrls - LocalNetworkAccessAllowedForUrls For detailed information about valid URL pattern syntax, see: https://learn.microsoft.com/deployedge/edge-learnmore-ent-policy-url-patterns For more information about Local Network Access, see: https://wicg.github.io/local-network-access/ Note: This policy blocks specified public websites from accessing private IP addresses. It helps reduce exposure of internal network resources unless access is explicitly permitted by policy. Example value: http://www.example.com:8080 [*.]example.edu *
