* HTTP channel will try to get this interface from its notificationCallbacks
* attribute, and if it doesn't find it there it will look for it from its
* loadGroup's notificationCallbacks attribute.
*
* These methods are called before onStartRequest, and should be handled
* SYNCHRONOUSLY.
*
* @deprecated Newly written code should use nsIChannelEventSink instead of this
