LiveBall now automatically supports domain-level cookies for as many domains as you want to point at it. For any respondent arriving on a LiveBall path, the system will automatically store their cookie with the second-level domain.
For example:
http://ecompaths.jwatch.org ==> cookie stored for "jwatch.org"
http://ecompaths.nejm.org ==> cookie stored for "nejm.org"
As with this example, both domains can point to the same LiveBall system. This domain-level cookie feature requires no configuration in the console.
