IROTransportChannelEx
Overview
The IROTransportChannelEx interface extends the IROTransportChannel interface with a BeforeDispatch method, allowing to do a some preparation before performing the actual message dispatching.
The TROAsyncProxy class uses this interface (if the used TransportChannel supports it) in the **__DispatchAsyncRequest** method.
