5.3 Third-Party Listener Support

Oracle Application Server can also use two other web servers (listeners) besides Apache:

• Java System Web Server (formerly Sun ONE Web Server)

• Microsoft Internet Information Server (IIS)

Oracle Application Server provides a proxy plug-in that allows you to transparently forward requests from these two servers to the Oracle HTTP Server. In this setup, the Oracle HTTP Server acts as a reverse HTTP proxy server; it receives and forwards a request to the appropriate content engine, but then points a redirect to the third-party listener. The Oracle HTTP Server as a proxy server mimics the host address and port of these listeners so that the proxy is completely transparent to any applications using the third-party listener.

Oracle Application Server also provides a lightweight single sign-on plug-in for these two servers. The plug-in is a partial implementation of the OracleAS Single Sign-On module. It allows these servers to seamlessly integrate with OracleAS Single Sign-On on the application server.
