PrefsEditor to prefsServer communication
Preferences Editors such as UI Options, the Exploration Tool and Preferences Management Tool (PMT), need to be able to communicate with the Preferences Server. However, the various Preferences Editors may all be on different domains than the Preferences Server and/or Online Flow Manager. UI Options, in particular, is likely a tool to be picked up by a wide variety of Integrators. This leads to a requirement to support cross domain requests between the Preferences Editor and the Online Flow Manager or Preferences Server.
