The big thing to remember in clustering is that temporary data needs  
to be stored in a backend that is available to all of the backends  
running PHP since (without any fancy sort of front end proxying) there  
is no guarantee all connections from a single user will go to the same  
machine.

So session storage, SQL, NoSQL, VFS, HashTable, etc. needs to be  
configured to be reachable globally within the cluster.
