The problem

Every time you edit a WordPress post, your cache is cleared in many places. The post page is cleared,
the homepage is cleared, the category, feeds, etc., etc. You edited just a single post or page but your cache
is cleared in many places!

This is cool because you don’t want stale content on your website.
But it’s not cool to make your next visitors facing slow pages!

The solution

Proxy Cache Warmer automatically warms up the pages which were purged from cache:

• It warms up purged caches as soon as you edit your content, via cron
• It warms up both Gzip and Brotli versions of cleared pages

All this allows for more happy visitors that hit your cache, and not slow backend!.

Installation

• Proxy Cache Warmer may act as supplementary plugin for Proxy Cache Purge plugin.
  So you may want to install the Proxy Cache Purge plugin.
• Next, install this plugin by downloading the zip file and extracting it to wp-content/plugins/proxy-cache-warmer directory.
• Activate both plugins.
• Ensure WordPress cron is configured correctly.

That’s it. After you edit a post, for example, it is cleared from cache alongisde all related pages like categories.
Upon next cron run, all those related URLs will be automatically warmed up.
