Is memcached a good way to store session share ammong web servers?

[Serhat Sakarya]

We're using clustered sessions too. However, we decided to kick out PHP's
session handler altogether and just use our own Session object. It's really
not that much more complicated. The session cookie handling is quite
straightforward.

I completely agree with your point regarding the load balancer. It's nice to
be able to connect to any node and still be logged in with the same session.
This moves the complexity away from possibly expensive load balancers.
