In a web server cluster, how do you do guys keep the php sessions? I

with apache backend webservers but If a user is logged into an php
app then this user goes always to the same backend server and if that
server goes down then the session is invalid.
How to deal with sessions?
Several options exist, but the most common is to store session data in
a database that can be accessed by all of the web servers.
Alternatives include using memcached but recently I read something
that suggested that can be problematic.
I believe the cluster support in Zend Platform includes this
functionality, so depending on your budget that may also be an option.
Just a note: you could have either one of the web servers acting as the
"session" server which the other web servers use or, if need be, a
dedicated "session" server. I wouldn't imagine you'd need that though
unless your site's really busy.
What do you mean by "session server"? How are you accessing the session
data on another server?
