Amazon Load Balancers are among those that do. Even if you use 
stickiness, you might want to consider using a memcached pool for your 
sessions.  I've had it work well in production environments.  Google 
will show you it's just an edit or two and a restart to implement it at 
least on Apache.. IIS? well..
