FAQ

Frequently Asked Questions

No, Cacheability Pro works with any caching layer that respects Cache-Control headers — including NGINX's proxy_cache, Cloudflare, Fastly, KeyCDN, and others. However, the ESI feature specifically requires Varnish or a CDN with ESI support.
Cacheability Pro is designed to complement existing caching plugins, not replace them. It hooks into WP Rocket's purge events to automatically warm purged URLs. The plugins handle different layers — WP Rocket handles page caching, while Cacheability Pro optimizes your reverse proxy/CDN layer.
When a page is purged, Cacheability Pro adds it to a warming queue. A cron job processes this queue in batches, making requests to each URL to populate the cache. URLs are prioritized: homepage first, then categories, then recent posts. You can also manually warm URLs via WP-CLI: wp cacheability warm --sitemap.
By default, posts and pages get a 2-week TTL (s-maxage=1209600). Search results and 404 pages get 1 hour. Feeds get 2 weeks. All values are configurable per content type in Settings → Cacheability Pro.
The core Cacheability plugin (free) provides soft 404 fixes and basic Cache-Control headers. Cacheability Pro adds cache warming, conditional GET (304), ESI support, cache diagnostics, and advanced per-page-type configuration.
