FeatureESI

Cache the page, not the person.

Edge Side Includes split a page into fragments. The public page is cached once; private blocks such as carts or greetings are filled in per visitor — so even personalised pages come from cache.

How it works

Hole-Punching Explained

  • The page is cached publicly with ESI placeholders
  • Each placeholder is fetched separately — public, private or uncached
  • LiteSpeed assembles the final page in microseconds
page.htmlbash
$ <header>…cached…</header>
$ <esi:include src="/cart-widget" cache-control="private" />
$ <main>…cached…</main>

Where ESI Shines

Mini-carts, wishlists and recently viewed items.
