Verify APO works

Last updated Sep 16, 2026 You can check whether or not APO is working by verifying APO headers are present. When APO is working, three headers are present: CF-Cache-Status, cf-apo-via, cf-edge-cache.

  1. Visit Uptrends.com ↗︎.
  2. In the text field, enter the URL for your WordPress homepage including the https://www..
  3. Select Start test. The Response Headers table displays.

  4. Locate the three header responses and their description. APO is working correctly when the headers exactly match the headers below.

  5. CF-Cache-Status | HIT

  6. The cf-cache-status header displays if the asset is served from the cache or was considered dynamic and served from the origin.
  7. cf-apo-via | tcache
  8. The cf-apo-via header returns the APO status for the given request.
  9. cf-edge-cache | cache, platform=wordpress
  10. The cf-edge-cache headers confirms the WordPress plugin is installed and enabled.

In a terminal, use the following cURL. Include the 'accept: text/html' header so the request is treated as a browser-like HTML request. This makes the test result deterministic. APO can also cache requests that omit the header, depending on the URL path. For more information, refer to FAQ on cf-cache-status results.

curl -svo /dev/null -A "CF" 'https://example.com/' -H 'accept: text/html' 2>&1 | grep 'cf-cache-status\|cf-edge\|cf-apo-via'

< cf-cache-status: HIT
< cf-apo-via: cache
< cf-edge-cache: cache,platform=wordpress

As always, cf-cache-status displays if the asset hit the cache or was considered dynamic and served from the origin.

  • cf-apo-via | tcache
  • The cf-apo-via header returns the APO status for the given request.
  • cf-edge-cache | cache, platform=wordpress
  • The cf-edge-cache headers confirms the WordPress plugin is installed and enabled.

Verify the APO integration and WordPress integration work

Open your WordPress site and publish a change. When the integration is working, the page is cached with cf-cache-status: HIT and cf-apo-via: tcache.
