Description
Codelab42 Cache Warming Connect connects your WordPress site to the cache-warmer.com service. When your page cache is cleared, or when you publish, update or unpublish content, the plugin tells cache-warmer.com to warm your site’s cache right away, so visitors never hit a cold cache.
Triggers
- A full purge in WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed Cache, WP Fastest Cache, Cache Enabler or Autoptimize.
- Publishing, updating, unpublishing or trashing any public post type.
- Switching themes, saving the Customizer, editing menus and installing plugin or theme updates.
- Manually: the «Warm cache now» button, the «Warm cache» admin bar link, or
wp cachewarmer warm.
Multiple triggers in one request are combined into a single run. After a run, further automatic triggers wait for the cooldown (5 minutes by default) and are then combined into one follow-up run, so bulk edits don’t trigger dozens of runs.
