The Sametime Proxy Server provides Lotus iNotes clients with an updated feature-rich Contact List and Chat UI, and eliminates the need for a JVM on the client for these services. The Sametime Proxy Server is a self-contained WebSphere® application that can easily be added to an existing iNotes/Sametime deployment with minimal configuration changes. For a new deployment, a minimum of three servers must be installed, one each for: iNotes, Sametime, and Sametime Proxy.

There are 3 Ways to Configure the ST Proxy within iNotes using, a Domino Configuration Document, Domino Policies or Domino ini parameters.
