[fw-general] Zend_Cache lifetime question

[holografix .]

Hi

Here's some code:

// Setup cache object
$frontendOptions = array(
    'lifetime' => 1800,
    'automatic_serialization' => true
);

$backendOptions = array(
    'cache_dir' => '../data/cache/'
);


$cache = Zend_Cache::factory(
    'Core',
    'File',
    $frontendOptions,
    $backendOptions
);

Later when getting data from cache

if (!$data = $cache->load('datafromdb')) {
     // Read data from db
     ...

     $cache->save($data, 'datafromdb');
}

The save() method accepts 5 params: data, id, tags, specificLifetime,
priority.

What happens if I tell cache to save this record with a specific lifetime of
3600 seconds?
Will it keep the new lifetime or the 1800 seconds defined in the frontend
options array ?

Thanks in advance.
