Netlet and Rewriter Proxies on Separate Nodes

To reduce the load on the Portal Server node and still provide the same level of
security at increased performance, you can install Netlet and Rewriter Proxies on
separate nodes. This deployment has an added advantage in that you can use a
proxy and shield the Portal Server from the DMZ. The node that runs these proxies
needs to be directly accessible from the DMZ.
Figure 5-15
from the Gateway is directed to the separate node, which in turn directs the traffic
through the proxies and to the required intranet hosts.
You can have multiple instances or installations of Netlet and Rewriter Proxies.
You can configure each Gateway to try to contact various instances of the proxies
in a round robin manner depending on availability.
