We’ll dig deeper into the ones numbers beneath.
Let’s check out how your WordPress web page’s efficiency can beef up when extra of its content material is “at the edge.”
What Is Edge Caching?
Lots of our WordPress web hosting shoppers are already benefiting from our integration with Cloudflare and its edge servers throughout the Kinsta CDN.

Edge Caching the HTML of WordPress pages is so much like managing the belongings within the CDN. A distinction is that managing a cache of recordsdata like pictures — which hardly ever exchange — is rather easy. It’s harder to regulate content material this is to begin with generated dynamically through WordPress, cached as static content material, after which regenerated anytime content material is edited.
How Does Content material Get Cached at the Edge?
Edge caches are populated through requests on your web page’s pages through browsers. If a web page isn’t already cached, the request is handed for your foundation WordPress web page, the place the web page may well be within the native cache or may well be generated once more through WordPress.

(The cellular cache does no longer distinguish between, say, iOS and Android units. Requests from capsules are grouped with desktop content material.)
