Combining Two Cache Applications on the Same Real Caches

Building on the fact that the P333R-LB allows for the same Real Servers to belong to
different Load Balancing applications (i.e. Application Redirection and Server Load
Balancing), it is possible to build a configuration that will implement transparent
caching and non-transparent proxy caching on the same physical machines (Figure
9.2).
In this case it is required that the caches working as non-transparent proxy caches
be configured as non-spoofing, i.e. caches that use their IP address as the source
address. This is as opposed to "Spoofing" caches which are capable of retaining the
characteristics of the incoming packet even when they forward the packet further
and keep the original Client IP address as the source address.
