Hi to all, First of all please accept my apologies if this question answered before. I've searched for a straight answer but I couldn't find one. Maybe I'm not looking in the right place.
So, I've started using the memcached for user sessions and I back it up with a database storage (in case of a miss or a memcached failure or other events). So far so good, I'm happy with the results, it really improves the performance. But, having two or more memcached servers and two or more web servers in a load balance, when a user logs out (basically it issues a delete in the memcached), can memcached client (I'm using the PHP client) or memcached server guarantee that the session (or any key for that matter) will be deleted from all memcached pool? Or I have to do this myself? Thank you, Adrian
