Incremental Static Regeneration

This page is statically generated with ISR. It revalidates every hour. Check the X-Cache header in DevTools to see cache status (HIT/STALE/MISS). Check server logs to verify static serving vs rendering.

How ISR Works
  1. First request: Page is rendered and cached (served with X-Cache: MISS)
  2. Subsequent requests: If cache is fresh (< 1h old), served from cache (X-Cache: HIT) - no server rendering, pure static serving
  3. Stale cache: If cache is stale, served stale content (X-Cache: STALE) while regenerating in background
  4. Background revalidation: Stale pages are regenerated automatically
