ln old versions of CF and FR, an exact match restriction of "/connector" (no quotes) worked to filter out FR's heartbeat requests. With CF 2021 and FR 8.8.0, that no longer works, I see tons of these:

<http://localhost/__cf_connector_heartbeat__>

I tried adding an exact match restriction like this:

__cf_connector_heartbeat__

, but it gets rejected, "The path you have entered is invalid, this will prevent restrictions from occurring. Press ok to continue or cancel to modify your request URL." Same happens without the leading and trailing underscores. EDIT: Using a regex of

cf_connector_heartbeat

also doesn't work, the heartbeat requests are still recorded. Same with

*cf_connector_heartbeat*

. What's the recommended approach?
