This class allows you to retrieve and modify the settings that affect how to QuickTime handles streaming of data over a network.
All of the properties and methods of this class allow you to programmatically setup the transport settings; some of these parameters can be accessed
by selecting the Custom... menu item of the Transport Setup popup list in the Advanced pane of the QuickTime preferences panel.
Using this class requires QuickTime 4.1 or later.
The QTPlgTransportPreferences does not provide any constructor at all. You obtain a valid
QTPlgTransportPreferences class instance, only by the
property of the
class.
The ˜QTPlgTransportPreferences class destructor, is called automatically when the
class is no more in use. Also, you can invoke the class destructor by setting the instance of the class to
nil.
Once a new class instance is returned, it is good practice to check the
class property to
be sure that the new object can be used. A QTPlgTransportPreferences object is always valid.
a comma–delimited list of URLs

You can specify only one of the transport types returned by the
class property.
Note that there must be always a
protocol active, so, deactivating a protocol could not be possible if the list of available transport types contains
just one protocol. This not being the case, deactivating the specified connection, will cause the first connection of another type found in the
list to be automatically activated
You can find about the currently active transport type by inspecting the
class property.
use this method to get or set the proxy server settings (if any) to be associated to the connection type specified by the
protocol parameter.
