What the _gac_ cookie does
Contains information related to marketing campaigns of the user. These are shared with Google AdWords / Google Ads when the Google Ads and Google Analytics accounts are linked together.
The name ends in a part that changes from visitor to visitor or site to site, so this entry covers every cookie whose name starts with _gac_.
Who sets it
