Combining Two Cache Applications on the Same Real Caches
Based on the fact that 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 implements transparent
caching and non-transparent proxy caching on the same physical machines, as
shown in Figure 14.15.
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.

The following configuration file is a result of the above configuration:
