Desktop Web Proxy Configuration User Guide Overview
Desktop Web Proxy (DWP) is a service that manages traffic from users' computers to the Web Security Service (WSS) by routing all traffic to the data center nearest the user's computer.
You can install DWP individually on each workstation using the downloaded msi installation package, or by using a Group Policy Object editor or other batch installation for a mass rollout.
Note: For information on Web Security Service, see the WSS Admin Guide.
