/**
 * This interface represents a control object for a Request/Response transport.
 * The normal flow of Axis2 is rooted at the transport -- this does not
 * allow for an acknowledgement to be transmitted before processing has
 * completed, nor does it allow for processing to be paused and resumed
 * on a separate thread without having a response be sent back.  This interface
 * enables both of those scenarios by allowing the transport to expose
 * controls to the rest of the engine via a callback.
