Check If Cache Is Working

Verify that your site is being served from the Fast edge network.

Check Response Headers

The easiest way to verify caching is working is to check the response headers. Open your browser's developer tools (F12), go to the Network tab, and look for these headers:

Fr-Cache: HIT
Fr-Cache-Hits: 1
Fr-Cache-Age: 120

What the headers mean

  • HITContent was served from the edge cache (fast!)
  • MISSContent was fetched from your origin server and is now cached
  • AgeNumber of seconds the content has been cached

First Request is Always a MISS

The first time any URL is requested after a cache purge or when the cache expires, you'll see a MISS. This is normal. Refresh the page and you should see a HIT.

Quick test: Visit your site, note the response time, then refresh. The second load should be significantly faster.
