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 5-19 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.
