Page cache enhances the speed and performance of your site by saving and serving static pages instead of calling for a page every time a user visits.
Page cache is detected by looking for an active page cache plugin as well as making three requests to the homepage and looking for one or more of the following HTTP client caching response headers:
cache-control, expires, age, last-modified, etag, x-cache-enabled, x-cache-disabled, x-srcache-store-status, x-srcache-fetch-status.
Median server response time was 81 milliseconds. This is less than the recommended 600 milliseconds threshold.
No client caching response headers were detected.
A page cache plugin was not detected.
