Assuiming you do transparent interception like everyone else then for
most setups, large as small, it's quite sufficient to balance based on
destination IP. But it's good if the load balancer has built-in HTTP
checks, proper monitoring each server for availability.

On the other hand, if your network (router/switch) supports WCCP then no
additional load balancer is needed as the load balancing you need is
already in the network equipment and almost auto-configured..

If you are doing explicit configuratoin (manaul or auto discovered) then
L7 is needed for load balancing if you want decent hit ratio, at least
until intra-array CARP routing gets implemented...
