Zinn® Cache: Set how long pages stay cached

Set how long pages stay cached

Choose a page cache lifetime, set a different one for products or posts, and control how long browsers keep images, CSS and JavaScript.

1. Start from the default — Zinn® Cache keeps a page for a week, 604800 seconds. Automatic purging clears a page when its content changes, so a long lifetime does not mean stale content.
2. Shorten it for fast-moving sites — If pages show information that changes without an edit — prices from a feed, event times — lower How long a page stays cached on the Page cache tab.
3. Add a rule per content type — Under Different lifetimes for different content, press Add a rule, choose a content type such as products, and enter seconds.
4. Set the browser lifetime — How long a visitor's browser keeps images and scripts applies to images, CSS and JavaScript only, never to pages. Leave it at 0 to let your host decide.
