Tá sraitheanna taisce iolracha ag an App Router a oibríonn le chéile. Soiléiríonn a thuiscint cén fáth go bhíonn dáta sean-aimseartha uaireanta agus conas smacht a bheith agat ar fhreshness.
Na ceithre thaisce
1. Request Memoization — dedupes identical fetch() calls within ONE render pass
2. Data Cache — persists fetch() results across requests & deploys (server)
3. Full Route Cache — caches the rendered HTML/RSC of static routes (build time)
4. Router Cache — client-side cache of visited routes (in the browser, per session)
