In either case, the proxy works only when other computers on your local network are configured to access the web through your server. To enforce this, you may need to configure your organization's firewall to prevent direct outgoing access to the web. The second proxy server is a reverse proxy server (not covered in this book), which can re-route incoming web traffic to various web servers — for example, balancing the load across several physical servers while appearing, to outside users, to be a single server.

NOTE

For more on setting up Mac OS X as a client to connect to a proxy server, see Chapter 10.
