# Why require a cache plugin?

 * An urgent recommendation to install a cache plugin appeared on the plugin page
   in the admin panel. Why do I need to do this when Autoptimize even has a feature
   called “clear cache”?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwhy-require-a-cache-plugin%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * because AO caches optimized CSS/ JS, but does not do page caching and you do 
   want page caching as the helps improve “server response time” tremendously 🙂
 * hope this clarifies,

   It’s strange that before now such a notification did not appear in the plugin.
   So what is the best cache plugin for interacting with Autoptimize?

 * well, the recommendation to use a page caching plugin has featured on the Autoptimize
   main page here on wordpress.org for ages, but the check & notification indeed
   is new 🙂
 * I would recommend KeyCDN Cache Enabler (easy to use, efficient, well written 
   and actively developed) or WP Super Cache (the grand-daddy of page caching, still
   maintained by the original developer who now works for Automattic).

   What should be the optimal settings for KeyCDN Cache Enabler and WP Super Cache
   so that they do not conflict with Autoptimize?

 * no conflicts that I can think of for WPSC, disable HTML opt. for KeyCDN, that
   should be it 🙂

   do you mean that I shouldn’t switch on the option “Minify HTML in cached pages
   excluding inline CSS and JavaScript” in the Cache Enabler by KeyCDN? In general,
   what should be the settings for this plugin to work well with yours? Because 
   I installed it, and there are no ticks everywhere

 * that’s keycdn cache enabler territory, so not my specialty really, but in general
   I would suggest to leave all unset except for “expiry”, and I would set that 
   to 8h. reason; some plugins that work with forms or AJAX request add a hidden“
   nonce” in the HTML and such a nonce expires after x hourse. if a page is cached“
   forever” (i.e. not expiring), the nonce becomes invalid and the form/ AJAX call
   won’t work any more.
 * hope this helps,
    frank
