Advanced Usage

Process-specific Cache Management

For managing the cache within a single PHP process (without affecting the drop-in file):

global $wp_object_cache;

// Enable cache for current process
$wp_object_cache->resurrect();

// Disable cache for current process
$wp_object_cache->die();

// Flush cache for current process
$wp_object_cache->flush();

This approach is useful when you need to temporarily enable/disable the cache for specific operations without affecting the global cache state.
