Hello,
How does piwik server knows about an existing visitor from his first party cookie sent in the _id parameter.?
what we see is that mysite.com sent action under _id=xxx and in the database the action is inserted under the third party cookie visitorId = yyy.
How does such mapping is done.
Regards,
