Cache External Scripts vs The Cache Purger

Often when trying to optimize the Google Pagespeed score, there is one script which still causing the ‘Leverage browser caching’ rule popping up: Google’s own gtag.js and/or analytics.js file… With this plugin you will be able to cache this file on your local server and enable browser caching for longer than 2 hours. The plugin will check every day if there is a newer version of the file to keep the cache up to date.

The Cache Purger takes the headache out of cache management. Instead of juggling a dozen different cache-clearing buttons across your stack, this plugin hooks into WordPress actions and fires them all at once — automatically, on a schedule, or with a single click from the admin bar. It covers the full spectrum: popular caching plugins, managed hosting environments, PHP-level caches (OPcache, APC, WinCache), server-level caches (Nginx, Varnish, PageSpeed), in-memory stores (Redis, Memcache, Memcached), and external CDN/WAF APIs (Cloudflare, Sucuri, Fastly). Every purge is configurable. Choose which cache types to include, which WordPress events should trigger a purge, and which specific posts, pages, CPTs, or field groups to exclude. You can also run purges on a WP Cron schedule, or kick one off manually via WP-CLI.
