Policy
Define a list of protocols that can not be silently blocked by anti-flood protection
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
Allows you to create a list of protocols and an associated list of allowed origin patterns, for each protocol. These origins aren't silently blocked from launching an external application by anti-flood protection. The trailing separator shouldn't be included when listing the protocol. For example, list "skype" instead of "skype:" or "skype://". If you configure this policy, a protocol is only permitted to bypass being silently blocked by anti-flood protection if: - the protocol is listed - the origin of the site trying to launch the protocol matches one of the origin patterns in that protocol's allowed_origins list. If either condition is false, anti-flood protection protection blocks the external protocol launch. If you don't configure this policy, no protocols can bypass being silently blocked. The origin-matching patterns use a similar format to those patterns for the 'URLBlocklist' (Block access to a list of URLs) policy, which are documented at https://go.microsoft.com/fwlink/?linkid=2095322. However, origin-matching patterns for this policy can't contain "/path" or "@query" elements. Any pattern that contains a "/path" or "@query" element is ignored. This policy doesn't work as expected with file://* wildcards. Example value: [ { "allowed_origins": [ "example.com", "http://www.example.com:8080" ], "protocol": "spotify" }, { "allowed_origins": [ "https://example.com", "https://.mail.example.com" ], "protocol": "msteams" }, { "allowed_origins": [ "*" ], "protocol": "msoutlook" } ]
