Prefetch Test Page

Response Header Being Sent

Link: <https://static.seanwashere.online/manifest.txt>; rel="prefetch"

⚠️ This header must be added server-side (Nginx, Apache, Cloudflare Transform Rule, or Workers). HTML meta tags do not trigger CF Prefetch URLs.

1
Purge https://static.seanwashere.online/mykauzk0mvhc1.png from Cloudflare cache on Zone B dashboard.
2
Confirm it's a MISS by opening Zone B test page or running:
curl -I https://static.seanwashere.online/mykauzk0mvhc1.png
3
Load this page (Zone A homepage) in an incognito tab — this triggers the Link prefetch header to Cloudflare.
4
Wait 5–10 seconds for Cloudflare to fetch the manifest and prefetch the resource.
5
Visit Zone B test page and check CF-Cache-Status on the image.
HIT = cross-zone prefetch works ✅
MISS = cross-zone prefetch does not work ❌

Note: Both shawncm.online and seanwashere.online must be proxied through Cloudflare (orange cloud). The Prefetch URLs feature must be enabled on Zone A (shawncm.online) under Speed → Settings → Content Optimization.
