The caching plugin, if any, must distinguish between mobile and desktop

If you have a plugin for a full page cache, be sure that it distinguishes between mobile and desktop,

Imagine this scenario:
– The cache is cleared or still not generated
– A user visits the page with a mobile device
– The cache is created according to the content served to mobile devices
– All other users will see the mobile content until the cache is expired or deleted, no matter if they have a desktop or a mobile device

If your caching plugin distinguishes between desktop and mobile it creates separate cache versions for mobile and you don’t have this kind of issue.

If your caching system doesn’t distinguish between mobile and desktop, you can’t use this plugin without having issues.

E.g. W3 Total Cache and WP Fastest Cache are server cache plugins that can handle the mobile cache.
