WP_CACHE constant

Thanks for the question.

The WP_CACHE constant, which you might choose to declare in your wp-config.php file, relates to page caching, not object caching. Therefore this object caching plugin does nothing with it.

Thanks. I could not find any docs about WP_CACHE, I only found similar misleading method names referring to object caching.

This is what WP docs say:

“Prior to WordPress 2.5, data stored using the wp_cache functions was stored persistently if you added define(‘WP_CACHE’, true) to your wp-config.php file.

This is no longer the case, and adding the define will have no effect unless you install a persistent cache plugin (see examples below).”

And, in the “examples below” there’s your plugin too.
