setUserSegmentsParam

public void setUserSegmentsParam(String param)

Note that if this class is being used in a production environment, it is highly recommended that the user segment parameter be removed from the navigation URL by adding the user segment parameter name to UrlNavigationStateBuilder.setRemoveAlways(java.util.List<java.lang.String>).

Parameters:

param - a String specifying the name of the user segment parameter. If null, no user segment information will be read from the HttpServletRequest.
