Caching Benefits
- Caching reduces server load, bandwidth use, and crucially, client-side speed.
- Implement caching mechanisms to improve perceived and actual load times.
Cache-Control Directives
- Cache-Control headers use directives to specify caching behavior.
max-age
sets the Time To Live (TTL) in seconds, determining freshness.
Stale-While-Revalidate
- The
stale-while-revalidate
directive serves stale content while fetching updates. - This improves perceived performance by using the browser cache.
