You have a HttpServletRequest and HttpServletResponse object sitting in the

In your SessionValidator, you can override what is in data.getParameters()
so that these values return something else. No need to move them.

You can ask it directly. From Turbine.java...
// Get the instance of the Session Validator.
SessionValidator sessionValidator =
(SessionValidator)ActionLoader
.getInstance().getInstance(configuration.getString(
"action.sessionvalidator"));
