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.
Practical, reproducible CDN/caching configuration that meaningfully increases edge cache hit rates and reduces origin load — useful for publishers and web platforms but not industry‑shifting.

Key Takeaways & Evidence Grounding
- Cloudflare Percent Cached for mustafaerbay.com.tr was 1.11% before the fix.
- Origin responses included "cache-control: public, max-age=0" and cf-cache-status: DYNAMIC, preventing CDN caching.
- The Astro Node adapter set max-age=0 for SSR/html responses, causing unnecessary origin traffic despite most pages being prerendered.
- The author used an nginx map to override Cache-Control for text/html to "public, max-age=300, s-maxage=3600, stale-while-revalidate=86400" and applied proxy_hide_header + add_header always.
- After deploying the nginx override, Cloudflare Percent Cached increased to 47.3% and cf-cache-status for HTML pages showed HIT.

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.
Serve WP Rocket Cache Directly with Apache/Nginx
The article explains how to reduce WordPress Server Response Time (TTFB) by configuring Apache (.htaccess) and Nginx to serve WP Rocket’s static HTML cache directly, bypassing PHP and WordPress when a cached file exists. It provides an Apache rewrite block to check for GET requests, absence of query strings, non-logged-in users, and the presence of wp-rocket cache files, and an Nginx location block using try_files to prefer WP Rocket cache files before falling back to WordPress. Benefits include lower TTFB, reduced CPU and PHP‑FPM load, better handling of traffic spikes, and improved PageSpeed/GTM metrics. Preconditions listed include having WP Rocket installed with generated cache files and backing up server configuration before changes. Published 2026-07-10.
Real Speedtest in Vanilla JS with Cloudflare API
A developer built a fully client-side speedtest in a single HTML file (~50 KB) using the public Cloudflare Speedtest API (speed.cloudflare.com). The tool measures HTTP-based ping (via small fetches and performance.now()), download speed (using the Streams API and response.body.getReader() to count chunks in real time), and upload speed (using XMLHttpRequest upload.onprogress with a fetch fallback). The UI is an SVG gauge animated with requestAnimationFrame. Users can enter their contracted tariff and the tool compares measured throughput to that tariff. The author highlights practicality (no frameworks or npm), anti-compression payloads for uploads, and Cloudflare’s permissive CORS and unauthenticated endpoints.
