Put expiration on memcached backend using xenforo

Hi,

---

I am wondering if its possible to put an expiration date on the files that gets cached through xenforo in Libmemcached.

This what I currently have in my config

Code:

$config['cache']['backend'] = 'Libmemcached';

$config['cache']['backendOptions'] = array(
'servers' => array(
array(
'host' => '127.0.0.1',
'port' => 11211,
'weight' => 1
)
)
);

Since I cache a lot of images and want them to be removed after 1 day, I have to flush the server every 24 hours, so I was wondering if there's a way to make them expire.
