CDN test — app.tfl.fund

Served by origin cd59eaea1280 at . This page lets you inspect what the CDN forwards to origin, and whether static assets are being cached at the edge.

1. Response headers seen by the browser

Headers on the request that fetched /headers.json?nocache. Look for CDN-set fields like x-cache, ar-*, cf-*, via, age, server.

2. Headers the origin received

What the CDN forwarded to the origin. Compare host, x-forwarded-for, x-real-ip, etc.

3. Edge cache test

Fetches /cached.txt (Cache-Control: public, max-age=3600) twice in a row. If the CDN is caching, the second response should be a HIT.
