Reverse Proxy

A proxy server serves Internet content to the intranet, while a reverse proxy serves intranet content to the Internet. Certain deployments of reverse proxy are configured to serve the Internet content to achieve load balancing and caching.

Figure 4–21 illustrates how you can configure a reverse proxy in front of the Gateway to serve both Internet and intranet content to authorized users. Whenever the Gateway serves web content, it needs to ensure that all subsequent browser requests based on this content are routed through the Gateway. This is achieved by identifying all URLs in this content and rewriting as appropriate.
