Assertivlogix Simple Cache

Assertivlogix Simple Cache is a lightweight WordPress plugin that improves front-end performance by caching rendered pages and minified CSS/JS assets to reduce server load and page load times.

• New: Optional lazy loading for <img> tags. Enable the checkbox in the plugin settings to automatically append loading="lazy" to cached HTML when your theme or host does not already handle it.
• Advanced CSS controls: remove unused selectors and duplicates, combine local stylesheets into an async-delivered bundle, and inline auto-generated or manual critical CSS for faster first paint.

Compatibility

This plugin relies on ob_start() buffering and is not supported on servers that already provide full-page caching at the base/server level (e.g., managed hosts with Varnish, LiteSpeed cache services, or proprietary edge caches). Combining two page caches can cause double-caching, stale pages, or broken purge flows, so we cannot offer support for those environments.
