Checkout acceleration

Speed up non-sensitive lookups without caching secrets or payment state.

Safe to accelerate

  • Shipping rate tables (short TTL)
  • Public inventory counts with SWR
  • CMS fragments for checkout chrome
  • Payment method list (not tokens)

Never cache

  • /cart, session cart APIs with Set-Cookie
  • Payment intents, client secrets, 3DS endpoints
  • Authenticated account JSON
PCI note. DT8 does not store cardholder data. Ensure origin responses for payment routes send Cache-Control: private, no-store.
