I know you guys have already thought about/discussed this, but can't you reduce the size of the page map by storing deltas? I thought I saw a thread about it in the dev list archives... What I'm getting at is that if you could significantly reduce the size of the page map, there might not be a compelling reason to store it outside of the session.
deltas/changes, whatever you call them, often have references to the page through anonymous classes, etc. so it ends up being the same
I beg to differ here. If you don't have to rely on sticky sessions then you get rock-solid failover and can therefore add and remove nodes at will (you're basically failing over constantly under normal operating conditions). The other big advantage is improved resource utilization across the farm. Your load balancers distribute on a request-by-request basis, and that can make a significant difference in overall throughput when compared to distributing on a session-by- session basis.
the con is that you lose data-locality in your caches. if you are using something like hibernate or doing caching on your own sticky sessions dramatically improve hit/miss ratio -igor
