What triggers page cache update, and how? (4 posts)

    In a multi-server config we have one Backend with Master MySQL db, and multiple Frontends with MySQL Slaves. New posts are added on the Backend.

    We face the issue of stale page cache on Frontends. My guess is that the Slave db update does not trigger hooks to update file cache on each of the Frontends.

    Also we disabled wp-cron in favor of the real cron job triggering wp-cron.php

    Question 1: what are the ways to trigger W3TC cache refresh on a Frontend via command line or a web request?

    Question 2: how can a cache refresh event on the Backend be populated off to a command line script perhaps?

    You might want to try this... I've had some luck w/it, albeit on very small sites:

    @adamsadowski thank you for the reply,

    Mentioned plugin doesn't work for my case, as the site is huge. There should be a way to control cache reload on remote servers on new post on the backend server - ideally by means of the W3TC plugin.

    Hope the plugin author will notice this thread.
