Whether the df_cache_save() will cache forever without the $lifeTime argument?

Hi
If do not specify $lifeTime will my object stay in cache forever?

Yes, because the $lifeTime argument is defaulted to null, and null means «cache forever» in the used Zend Framework implementation:

zendframework/zf1/blob/release-1.12.16/library/Zend/Cache/Core.php#L337-L348


/**
 * Save some data in a cache
 *
 * @param  mixed $data           Data to put in cache (can be another type than string if automatic_serialization is on)
 * @param  string $id             Cache id (if not set, the last cache id will be used)
 * @param  array $tags           Cache tags
 * @param  int $specificLifetime If != false, set a specific lifetime for this cache record (null => infinite lifetime)
 * @param  int   $priority         integer between 0 (very low priority) and 10 (maximum priority) used by some particular backends
 * @throws Zend_Cache_Exception
 * @return boolean True if no problem
 */
public function save($data, $id = null, $tags = array(), $specificLifetime = false, $priority = 8)
