We’ve configured Piwik with QueuedTracking plugin and use_third_party_id_cookie=1.

The part of the code that sets the cookie is in Tracker/Visit.php:

But that does not make sense, as there is no client to set the cookie to!
I’m new to Piwik and I may be missing something, but is it possible to use use_third_party_id_cookie together with QueuedTracking?
