What the UID cookie does

Collects information of the user and his/her movement, such as timestamp for visits, most recently loaded pages and IP address. The data is used by the marketing research network, Scorecard Research, to analyse traffic patterns and carry out surveys to help their clients better understand the customer's preferences.

Who sets it
