Setting the policy provides access to the listed URLs, as exceptions to 'URLBlocklist' (Block access to a list of URLs).
Format the URL pattern according to https://go.microsoft.com/fwlink/?linkid=2095322.
You can use this policy to open exceptions to restrictive block lists. For example, you can include '*' in the block list to block all requests, and then use this policy to allow access to a limited list of URLs. You can use this policy to open exceptions to certain schemes, subdomains of other domains, ports, or specific paths.
The most specific filter determines if a URL is blocked or allowed. The allowed list takes precedence over the block list.
This policy is limited to 1000 entries; subsequent entries are ignored.
This policy also allows the browser to automatically invoke external applications registered as protocol handlers for protocols like "tel:" or "ssh:".
If you don't configure this policy, there are no exceptions to the block list in the 'URLBlocklist' policy.
