What the lidc cookie does

lidc is used to facilitate data center selection. It records which LinkedIn data center should handle the browser's requests, so routing stays consistent while it lasts.

LinkedIn lists it under preferences, features and services, with a 24 hour lifetime. On other sites it appears as a third-party cookie on .linkedin.com whenever LinkedIn content or the Insight Tag loads.
