Configuring Reverse Proxy Servers
Networking 4-7
To configure the server so that the PPE loops back to the LBR for the loopback
connections, you must perform the following steps:
Install a Single Portal and Wireless Middle-Tier
■ Step 1: Install a Single Portal and Wireless Middle-Tier (M1)
■ Step 2: Configure OracleAS Portal on M1 to Be Accessed Through the LBR
■ Step 3: Confirm That OracleAS Portal is Up and Running
■ Step 5: Configure the New Middle-Tier (M2) to Run Your Existing Portal
For complete information about these steps, see Chapter 5 of the Oracle Application
Server Portal Configuration Guide.
4.5 Configuring Reverse Proxy Servers
A reverse proxy server is a host process that is used as part of a firewall architecture to
isolate the internal hosts from the externally accessible host(s). It does this by
providing a proxy through which external requests must pass to access internal
services. Typically, a proxy server takes the form of a dual-homed host. This means
that it is a host with two network interface cards. One interface connects to the external
network, and the other interface connects to the internal network, or demilitarized
zone (DMZ) of the firewall.
Figure 4–2 shows an architecture in which the browser accesses the server through the
hostname that is published by the proxy server. The proxy server then forwards the
request to the actual host within the firewall.
For this example, we will assume that you have properly configured the OracleAS
Single Sign-On server to work with the reverse proxy server.
Note: You will notice that the infrastructure is behind the LBR.
The infrastructure can be one host, or distributed over multiple
hosts. In order to configure the infrastructure properly, refer to the
Chapter titled "Advanced Configurations" in the Oracle Application
Server Single Sign-On Administrator’s Guide

Application Server 10g Installation Guide.
