persistant data

[Evert|Rooftop]

Hi,

I would really like to use memcached to store the users session data.. 
Im using the database for that now, because I need to retain the session 
accross multiple servers.

however, as the cache fills up it might delete 'older' data, so are 
there plans to implement some sort of 'force persistant' flag that will 
always retain the data, as long as the ttl is not expired?

I'm using the PHP PECL api.
