Our WordPress platform is optimised with the Stack Cache plugin.
The CDN and StackCache can complement each other. The CDN will handle static cache of static file types, whilst StackCache handles dynamic caching.
For websites on the WordPress Platform (i.e. with StackCache), dynamic content is cached with the default expiry times set.
You can edit these values from the Edge Caching section of the hosting control panel, or directly from within StackCache in the WordPress admin area. In addition, you can cache any other dynamic content using public Cache-Control and Expires headers via a .htaccess file - however, this is recommended only for advanced users only.
