Advanced Server-Side Caching Patterns in Next.js

Short summary

A deep dive into server-side caching patterns in Next.js App Router, covering RSC payload caching, extended fetch API caching with revalidation options, and per-request memoization. Explains how Next.js deduplicates identical fetch calls within a render cycle and how content-driven revalidation via revalidatePath and revalidateTag offers better freshness than time-based approaches. Includes code examples for each pattern.
