How cached pages are delivered

Super Page Cache PRO is the paid edition of Super Page Cache, a WordPress extension that caches HTML pages and static files. Disk caching stores them on the server and works without a CDN. You can connect Cloudflare with an API key or token to deliver cached content through its edge network using Cache Rules. Cloudflare Free, Pro and Enterprise plans are supported, along with automatic purging, cron jobs and integrated metrics.

PRO includes performance controls to the plugin’s full-page, disk, browser and CDN caching features.

Cache behavior and lifecycle

Set custom cache expiration periods or choose never to expire. Exclusions cover cookies, query parameters, URIs, AMP, feeds and the REST API. Response-header management and a cache buster let logged-in visitors bypass cached pages. The plugin can purge the cache when content changes, include related pages in a purge, clear HTML only or clear the full cache. Queue-based background processing helps prevent server overload.

PRO controls

• Marketing parameters: Handle UTM, affiliate and tracking codes to improve cache hit rates.
• JavaScript deferral: Defer scripts to help eliminate render-blocking JavaScript.
• JavaScript delay: Load scripts when visitors interact with the page.
• Advanced lazy loading: Use viewport detection and above-the-fold optimization for supported content.
• Advanced exclusions: Exclude specific JavaScript files or pages from caching when they need various treatment.
• Priority support: Get faster email response times.

Other performance tools and compatibility

The plugin also includes browser caching; lazy loading for images, videos, iframes and background images; local Google Fonts; unused CSS and JavaScript removal; and an assets manager for enabling or disabling CSS and JavaScript on individual pages. A preloader can use sitemaps, menus or recent posts, and run manually or by cron.

Compatibility includes WooCommerce, Easy Digital Downloads, Varnish, OPcache, Kinsta, WP Engine and SpinupWP. The plugin also supports internal-link prefetching with Instant.page. Disable page caching in other caching extensions such as WP Rocket, LiteSpeed Cache or W3 Total Cache. It can be used alongside Optimole, Autoptimize, Perfmatters and ShortPixel for asset optimization.

Setup

Install and activate Super Page Cache PRO on your WordPress website, then open its dashboard for settings and built-in documentation. Most users can begin with the defaults. To use Cloudflare, connect an account with an API key or token. Review exclusions and JavaScript controls before enabling advanced behavior on a production site.
