CacheBoost Warmer closes that gap. Whenever a purge or invalidation occurs in WordPress, it tells the CacheBoost API to re-warm the affected pages, so your cache stays hot and every visitor hits a fast, cached response. **Features:** * **Smart warming** — resolves purged post/term URLs and triggers a targeted warm( only the affected pages). * **Full warming** — triggers a full site warming on global events (theme switch, plugin upgrade, full cache purge). * **Deduplication** — multiple purge events within the same HTTP request produce a single API call. * **Non-blocking** — uses `wp_remote_post()` with `blocking => false`; never delays a WordPress request. * **WooCommerce** — warms product and category pages on save; optional stock-change warming. * **Cache plugin integrations** — WP Rocket, W3 Total Cache, LiteSpeed Cache, WP Super Cache. * **Multisite** — each sub-site has its own settings and API key. ### Configuration #### Step 1 — Get your API key 1. Log in to [app.cache-boost.com](https://app.cache-boost.com). 2. Go to your [profile](https://app.cache-boost.com/profile) and click **New API key**. 3. Select the scopes: `sites:read`, `boosts:read`, `boosts:write`, `runs:read`. 4. Copy the generated key (format `cb_live_…`). #### Step 2 — Configure the plugin Go to the **CacheBoost** menu: * **Enable** — master on/off switch. * **API Key** — paste your `cb_live_...` key. * **Warming triggers** — Smart (targeted URLs) and/or Full (entire site), each can be toggled independently. * **Stock Warming** — (WooCommerce only) warm product pages after stock changes. * **Test Connection** — validate your API key without leaving the admin. ### Cache plugin support WP Rocket, W3 Total Cache, LiteSpeed Cache, WP Super Cache ### External Services This plugin sends data to the CacheBoost API (https://api.cache-boost.com) to trigger cache warming jobs after a purge event. Data transmitted includes the site URL, the list of page URLs to warm and a timestamp. No personal user data is sent. Requests are only made when: – The plugin is enabled in the CacheBoost settings– A valid API key (format: cb_live_…) has been configured CacheBoost Terms of Service: https://www.cache-boost.com/terms ## Screenshots [[ [[ ## Installation 1. Upload the `cacheboost-warmer` folder to `wp-content/plugins/`. 2. Activate the plugin via **Plugins Installed Plugins**. 3. Go to the **CacheBoost** menu in the admin sidebar and enter your API key. ## FAQ ### Does this plugin slow down my WordPress site? No. Warming notifications are fire-and-forget (`blocking => false`) and never delay a request. The dashboard widget and history page fetch stats from the API; widget results are cached for a couple of minutes. ### Does it work on multisite? Yes, but do not network-activate. Each sub-site should have its own settings and API key. ### What is sent to the CacheBoost API? Only the site URL, the list of page URLs to warm (Smart mode), and a timestamp. No credentials and no personal data are ever transmitted. ### What happens if my API key is invalid or the API is unreachable? Nothing breaks on the front end. Because notifications are non-blocking, a failed or rejected request is logged silently and your WordPress pages keep serving as usual. Use **Test Connection** in the admin to validate the key. ### Does CacheBoost work with my CDN? CacheBoost works with any CDN that serves content via HTTP — Cloudflare, Fastly, BunnyCDN, KeyCDN, and more. If your CDN caches HTTP responses, CacheBoost can warm it. ### Does CacheBoost work without a CDN? Absolutely. CacheBoost works with any caching layer — not just CDNs. If your site uses Varnish, Redis, a file cache, a database cache, or any HTTP-based caching system, CacheBoost can warm it. As long as your pages are served faster on the second request, CacheBoost is useful. ### Will the warming requests affect my server load? Warming requests are sent at a controlled rate to avoid overloading your origin server. You can configure the concurrency and request rate per boost from your CacheBoost dashboard. ### What if my site has thousands of URLs? No problem. On a full warm, CacheBoost reads your sitemap (including multi-level and sitemap index files) with no limit on the number of URLs. Every page gets warmed, regardless of the size of your site. ### Is my data safe? CacheBoost only sends HTTP requests to your public URLs — the same requests any visitor would make. No credentials and no private data are ever accessed. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “CacheBoost Warmer” is open source software.
