About this plugin

- Fast page serving via WordPress advanced-cache.php (only if no other cache plugin already provides it)
- Optional button to add define( 'WP_CACHE', true ); to wp-config.php (backup is created first)
- Purge all / purge URL from the admin bar
- Auto-purge on content updates
- Bypasses logged-in users, carts, POST, previews, feeds, search, and sitemaps
- Optional conservative HTML minify

Privacy
Flex Cache stores cached HTML for anonymous pages as files under wp-content/cache/flex-cache/. It does not log visitors, IP addresses, or user agents.
If you turn Redis on, the same HTML is also stored in Redis on a host you configure. Your Redis password (if you set one) is stored only in the WordPress options table via the Settings API. json in the cache folder (enabled, TTL, host, port — no password).
php yourself. Flex Cache does not send data to FLEX or any third-party service.
Redis is software you or your host run. io.
Limitations
- Logged-in visits are never cached, including the WordPress admin.
- Only one plugin can provide fast page serving. Flex Cache will not overwrite another plugin’s advanced-cache.php.
- Enabling WordPress cache mode writes one line to wp-config.php only when you click the button (or you can add the line yourself).
