Why multi-region matters
- Faster TTFB → better LCP and engagement.
- Reduced origin load; resilience during spikes.
- Better experience for APAC/EMEA users without new infrastructure.
How edge caching works
- Points of presence (POPs) serve cached responses close to users.
- Reverse proxy normalizes headers, compresses payloads, and enforces TLS.
- Cache keys include path, query (when needed), and device hints.
Routing patterns for /blog
- Map
/blog/*to origin host; strip/blogupstream. - Keep admin paths uncached and possibly geofenced.
- Use stale-while-revalidate to refresh in background.
Cache rules for dynamic vs static
- HTML: short TTL for anonymous traffic; bypass on auth cookies.
- Static assets: long TTL with versioned filenames.
- Images: serve WebP/AVIF when supported; provide JPEG fallback.
Measuring and tuning
- Track cache hit ratio, TTFB, and LCP by region (use Chrome UX or RUM).
- Add rules for heavy templates; collapse cache keys to avoid fragmentation.
- Test failover by simulating origin downtime; ensure graceful degradation.
Common pitfalls
- Forgetting to cache-control static assets.
- Over-caching HTML with logged-in cookies.
- Redirect chains from legacy hosts; fix at the edge.
Playbook by site type
- Content-heavy WordPress: cache HTML for anonymous users with short TTL; long TTL for static; bypass on auth cookies. Add image optimization and lazy-load.
- Blogger/Webflow/Ghost: simpler HTML; edge caching is straightforward—just ensure proper cache keys and canonical URLs.
- App+blog combos: keep
/blogon the proxy with caching; leave app routes uncached or lightly cached; separate origins if needed.
Advanced FAQ
How do I pick TTLs?
HTML: 30–300s with stale-while-revalidate; static assets: hours to days with versioning. Adjust per template volatility.
Can I cache personalized content?
Avoid unless you segment by cookie or header. Prefer caching anonymous variants and bypassing when personalized.
How to handle purge?
Purge by URL or by cache tag if supported. Versioned assets avoid broad purges.
How to prove impact?
Compare pre/post TTFB and LCP for three regions. Track cache hit ratio and origin load drop; annotate analytics.
