# Headers not detected

 * I’ve installed redis on the server and activated the Redis Object Cache plugin.
 * The plugin settings indicate everything is setup properly, yet my Site Health
   continues to state times slightly higher than the 600ms recommendation (same 
   as before).
 * Also indicates  **No client caching response headers were detected.**
 * Diagnostics:

 * Thanks. That notice is related to Comet Cache’s page cache.
 * Redis Object Cache does not cache pages, it caches objects such as queries and
   metadata 👍

 * Thanks. So what would you suggest in terms of performance because the Redis plugin
   is not impacting performance at all.

 * Redis Object Cache does not send any headers, the notice might be related to 
   your CDN or hosting provider.

 * No, Redis Object Cache is a pure performance plugin. But if you you benchmark
   the page cache, it will never kick in. Try benchmarking the WordPress admin (
   or checkouts) with and without Redis Object Cache.
