Sun Java System Web Server 7.0 integrates the reverse proxy functionality within the core server.
When web server is configured with reverse proxy functionality, it acts as a proxy for one or more backend servers and serves as a single point of access or gateway in a server farm. In a reverse proxy setup, the web server forwards the HTTP request it received from the browser client to the appropriate backend server. The HTML response from the backend server is sent back to the browser through the web server. Thus, the web server with reverse proxy hides the existence of backend servers to the browser.
Web Server provides GUI and CLI support for configuring the reverse proxy.
For information about configuring reverse proxy, see Configuring Reverse Proxy in Web Server in Oracle iPlanet Web Server 7.0.9 Administrator’s Guide.
