Full-Page Edge Caching for Laravel with Cloudflare
A technical guide describing how Web Pioneer implemented full-page HTML edge caching for Laravel applications using a small origin-side middleware (EdgeCache) plus a Cloudflare cache rule set to respect origin headers. The middleware makes cacheability decisions in the Laravel app, removes Set-Cookie for safe anonymous 200 HTML GET responses, and emits Cache-Control: public, s-maxage=600. The article documents operational lessons (misleading HEAD checks, purge-on-deploy, stray Set-Cookie regressions, and the need to version assets), explains why Cloudflare must respect origin headers (to avoid caching 404s or pinned stale HTML), and reports reduced TTFB and origin load for anonymous content while warning against caching per-user pages like carts and dashboards.
Practical guide for implementing origin-controlled full-page CDN caching reduces latency and origin load for anonymous content — useful for publishers and high-traffic sites but not industry-shifting.

Key Takeaways & Evidence Grounding
- Web Pioneer implemented full-page HTML edge caching for Laravel using an origin-side middleware called EdgeCache on web-pioneer.com.
- The EdgeCache middleware removes Set-Cookie and sets Cache-Control: public, max-age=0, s-maxage=600 for anonymous GET 200 HTML responses.
- Cloudflare must be configured to 'respect existing headers' (Edge TTL = respect existing headers) to avoid caching error pages and stale HTML; override mode previously caused cached 404s and stale content incidents.
- Four operational gotchas were highlighted: HEAD requests can misreport cache status, purge on every HTML deploy is required, any stray Set-Cookie silently prevents caching, and static assets must be version-stamped to avoid browser-side staleness.

Cloudflare HTML Cache at 1.1% Fixed with Nginx Map
A developer observed Cloudflare’s Percent Cached for mustafaerbay.com.tr stuck at 1.11% because the origin returned HTML with Cache-Control: public, max-age=0 (cf-cache-status: DYNAMIC). The Astro Node adapter set max-age=0 for SSR/html responses, preventing Cloudflare from caching pages. The author implemented an nginx map that overrides Cache-Control based on Content-Type: for text/html it sets "public, max-age=300, s-maxage=3600, stale-while-revalidate=86400", while passing through upstream headers for assets and /api/*. Using proxy_hide_header and add_header ... always ensured the header is present for all status codes. Verification showed cf-cache-status: HIT and the dashboard Percent Cached rose from 1.1% to 47.3%, reducing origin requests and improving page load times.
Advanced Server-Side Caching in Next.js
This technical guide details advanced server-side caching strategies for Next.js applications, covering the Pages and App routers, React Server Components, and Next.js's built-in data cache. It explains how the extended fetch API supports cache modes (force-cache, no-store) and revalidation options (next.revalidate, tags), and shows how to programmatically revalidate cached data with revalidateTag. The article describes HTTP caching headers (Cache-Control, ETag, Last-Modified) for influencing CDNs and clients, compares in-memory caching (node-cache) with external caches (Redis) for scalability, and discusses edge caching via CDNs and edge functions. Strategic considerations—granularity, freshness vs. performance, personalization, invalidation, and monitoring—are summarized to help developers design resilient, high-performance caching architectures.
Service Workers Boost PWA Caching and Performance
This technical guide explains how service workers improve Progressive Web App (PWA) speed, reliability, and offline capability by intercepting network requests and applying caching strategies. It defines service workers as background JavaScript that sits between the app and the network, outlines what to cache (an app shell: HTML, CSS, JS, fonts, logos, essential images), and describes four main caching strategies: Cache First, Network First, Stale-While-Revalidate, and Cache Only. The article emphasizes best practices including versioned cache names, deleting old caches on activation, providing a custom offline fallback page, limiting large files, testing with browser DevTools (simulate offline, throttle network), and requiring HTTPS in production. Practical use cases (e-commerce, news, productivity, education, travel) are listed to show retention and UX benefits.
