Input (grade 11): However, the requests are not anonymous to the anonymizing proxy server, and so a degree of trust is present between the proxy server and the user.
Output (grade 10): This is sometimes called anonymizing because it makes the client anonymous A second advantage is that when the proxy server itself is able to serve the request made by the client, it will not contact the remote server any more. So the load on the remote server will be reduced by using a proxy server.
