Yes, almost all servers running with views are recursive. They will also 
typically have some auth data, but the biggest part is that the view 
caches need to not pollute each other with data. The general model is 
the the inside view needs to cache the internet data plus the private 
network data for all the inside connections. The outside view needs to 
cache just the outside data for the bastion hosts' external interfaces.
