Define a list of allowed URLs

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 blocklists. For example, you can include '*' in the blocklist 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 blocked 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 blocklist in the 'URLBlocklist' policy.

This policy doesn't work as expected with file://* wildcards.

Example value:

contoso.com
https://ssl.server.com
hosting.com/good_path
https://server:8080/path
.exact.hostname.com
