ObjectNest Cache

ObjectNest Cache makes persistent object caching understandable and manageable inside WordPress. It connects WordPress to a Memcached server through the standard wp-content/object-cache.php drop-in and explains whether the PHP extension, server, and drop-in are working.

The plugin stays local-first. It does not create an account, send site data to a remote service, add frontend assets, or track visitors.

Features

• Automatic discovery of common local Memcached endpoints.
• Custom Memcached host and port configuration.
• Connection test with actionable diagnostics.
• Safe connect and disconnect controls.
• Refuses to overwrite a foreign object-cache.php drop-in.
• Live Memcached version, uptime, hit ratio, items, memory, connections, traffic, and evictions.
• Optional disk object-cache fallback when Memcached is unavailable.
• Explicit administrator-only cache flush action protected by a nonce.
• Responsive, keyboard-friendly WordPress admin dashboard.
• A compact WordPress Dashboard widget showing live hit ratio, memory, items, evictions, and uptime.

Requirements

• WordPress 5.8 or newer.
• PHP 7.4 or newer.
• For Memcached: the PECL memcached extension and a reachable Memcached server.
• The legacy PECL memcache extension is not the extension used by the Memcached backend.

Safety

ObjectNest never overwrites an object-cache.php file it does not own. Memcached should listen on a private interface or protected network; do not expose it to the public internet. Cache keys are salted per WordPress installation when the generated drop-in is created.

The Flush action affects the connected cache backend’s pool. Use it only when you understand whether that server is shared with other applications.
