My PHP API Returned no-store and Cloudflare Passed Everything Through: Overriding Only the Edge TTL
The list API behind my wallpaper apps returned no-store, so putting Cloudflare in front of it changed nothing: every request still reached the origin. This note covers a Cache Rule that overrides only the edge TTL, a small script that proves it works, and a deploy step that pairs upload and purge so stale responses don't linger.
I Swapped an Immutable Asset at the Same URL, and Only the Browser Kept the Old Copy
Overwrite a long-cached JS file at the same URL and neither a CDN purge nor a refresh will make the browser fetch it again. Four delivery styles — same URL, no-cache, query string, content-hash filename — compared in Chromium, plus a complete build-step script that adds the hash.
Purging Cloudflare Didn't Bring Back the New Wallpapers: the Stale JPEGs Were Held by XPageSpeed on the Origin
An operations record from a wallpaper app: images overwritten at the same URL kept arriving stale even after a Cloudflare purge. Covers the three-way local/origin/edge probe that names the guilty layer, when prefix purge beats per-URL purge, and how to switch off Xserver's XPageSpeed in .htaccess without a 500.
