13.2. Configuring the PDR proxy
Each page that wants to connect to the PDR must create an instance of the PerspectiveProxy class. The creator of this class has a 'channel' parameter that must be bound to an instance of either SharedWorkerChannel or InternalChannel - the latter only for Safari.
The page does so through calling configurePDRproxy with a string argument that signals what kind of Channel should be created.

Safari is the exception. The rest of this text is oriented to other browsers. The Safari case will be treated in its own paragraph at the end of this chapter. |
configurePDRproxy creates both a Channel instance and a PerspectivesProxy instance (and provides the former as argument to the latter’s constructor). It also fulfills two promises: PDRproxy and SharedWorkerChannelPromise.
