Verify APO works

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.
  • CF-Cache-Status | HIT
    • The cf-cache-status header displays if the asset is served from 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.

In a terminal, use the following cURL. The header 'accept: text/html' is important

Terminal window
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.

  • The cf-apo-via header returns the APO status for the given request.
  • The cf-edge-cache header means 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
