The purpose of this article is to provide steps for configuring Oracle9i Application
Server (9iAS) Release 2 (9.0.2) SSO (Single Sign-On) Server when a software or
hardware device such as a reverse proxy is deployed in front of the SSO (Single
Sign-On) Server.

For OracleAS 10g version 9.0.4 see Oracle Application Server Single Sign-On
Administrator's Guide 10g (9.0.4) Chapter 9 Advanced Configurations - Deploying
OracleAS Single Sign-On with a Proxy Server

When any software or hardware devices such as a reverse proxy, load balancer,
or Web Server is inserted between the end-user browsers and the SSO (Single Sign-On)
Server, this will result in changing the effective URL of the SSO (Single Sign-On)
server from the browser's perspective. Such devices can either be NON-SSL or

Deploying a reverse proxy type of device in front of SSO (Single Sign-On) Server
may be done for a variety of reasons including:

o Hiding the hostname of the SSO (Single Sign-On) Server
o Terminating SSL connections to another server instead of SSO (Single Sign-On)
o Limiting the number of ports that need to be opened on a firewall

The SSO (Single Sign-On) Server must be re-configured to handle the above changes.
Please note, the SSO (Single Sign-On) can only bind to one protocol, hostname and port.
For example, if you configured a SSL-Enable reverse proxy in front of SSO Server.
Then all subsequent SSO requests must be done via that SSL-Enabled reverse proxy.
