The Anonymizer Project

In many respects, this anonymizer is like the previously described network proxies. However, this anonymizer is web-based, in contrast to most (corporate) proxies, which provide the only path from a local network to the Internet. Since all traffic between the private network and the Internet passes through these network proxies, it is simpler for them to modify traffic. Our web-based proxy, in contrast, runs on a web script and must contain the traffic within a browser. What this means is that every link passing through a web-based proxy must be modified to keep the web surfer on the anonymizer's web page, which is shown in Figure 10-5.
