Data delivery to ActiveX controls hosted by Internet Explorer

Through some experimentation I have found that, at least where full-page controls are concerned, Internet Explorer calls IPersistPropertyBag2::Load to inform the control of the URI for the data via a "src" property. But is there some mechanism by which the container simply delivers the data to the control as a stream? Or is the control entirely responsible for fetching the data using the URI?

I would have thought that, by the time the control is instantiated, the browser would already have a stream for the data (that it could presumably hand off to a successfully-instantiated control).
