 * I am using Litespeed and I get the following error even though mobile cache is
   turned on.
 * “The AMP plugin performs at its best when page caching is enabled. This is because
   the additional optimizations performed require additional server processing time,
   and page caching ensures that responses are served quickly.
 * Page caching is detected by looking for an active page caching 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, x-proxy-cache, cf-cache-status, x-kinsta-cache, x-cache-enabled,
   x-cache-disabled, cf-apo-via, x-srcache-store-status, x-srcache-fetch-status,
   cf-edge-cache.
 * Median server response time was 86 milliseconds. This is less than the 600 millisecond
   threshold.
   No client caching response headers were detected.A page caching plugin
   was not detected.”
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Famp-cache-error%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi,
 * I am support staff of LiteSpeed Cache plugin , the issue here seems that AMP 
   doesn’t detect our cache header `x-litespeed-cache`
 * is there any filter we can use ? like `site_status_page_cache_supported_cache_headers`
   filter on wordpress ?
 * Best regards,

 * Hello [@onurkk](https://wordpress.org/support/users/onurkk/)
 * Thank you for contacting us, it is a warning and not error.
 * If you are using the Cache plugin then you can ignore the warning, as mentioned
   in the notice it only checks those headers and serves the purpose of informing
   users that they need to use the cache plugin for better AMP performance.
 * Hello [@qtwrk](https://wordpress.org/support/users/qtwrk/)
 * This is a nice suggestion! I have created [github issues](https://github.com/ampproject/amp-wp/issues/7643)
   for same
 * We hope this helps!

 * I think we can just remove the Site Health test for page caching from the AMP
   plugin. It actually served as [the basis](https://github.com/WordPress/performance/issues/220)
   for what was [merged](https://core.trac.wordpress.org/ticket/56041) into WordPress
   core. So now it is redundant.
