I'm reviewing the cookies served up from my website and one of them is a first-party cookie __qca which seems to be set by Quantcast.I'm sure this is just used for tracking, but I can't find this cookie discussed anywhere on Quantcast's website or generally on the web at all?Can anyone provide a reference or further information on what this cookie actually does?Thanks.
What does the Quantcast __qca cookie do?
