List of URL patterns. Network requests initiated from websites served by matching origins to the local device are blocked from issuing Local Network Access requests. For origins not covered by the patterns specified here, the user's personal configuration will apply. For detailed information on valid URL patterns, please see https://chromeenterprise.google/policies/url-patterns/. See https://wicg.github.io/local-network-access/ for <ph name="LOCAL_NETWORK_ACCESS">Local Network Access</ph> restrictions. There are multiple policies listing origins that impact requests to the local device.
