CacheBoost Warmer

Every cache purge leaves your pages «cold»: the first visitor after a purge pays the full origin render time. 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.
2. Go to your 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.
