## The brief

Vercel’s CDN now declines to cache origin responses whose Vary header includes Cookie, while continuing to serve those responses normally. The company says cookie-dependent variations often produce cache entries with little reuse. Its guidance distinguishes content that is identical across visitors from personalized responses, recommending private cache controls for the latter. Other supported Vary headers retain their existing caching behavior.
