What the _pk_ses cookie does
Short lived cookies used to temporarily store data for the visit
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 _pk_ses.
Who sets it
Consent category: analytics
Analytics cookies measure how a site is used, in aggregate: pages seen, sessions, where visitors came from. Under the GDPR they need consent before they are set, and Google Consent Mode can model what is lost when visitors decline.
