The async interface usually has a void return type, but it can optionally
return a Request object, like this -
import com.google.gwt.http.client.Request;
interface MyServiceAsync {
public Request myMethod(String s, AsyncCallback<String> callback);
}
So, after you make your Async call, hold on to the Request object. When you
wish to cancel the calls, invoke the request.cancel() method.
