Description

WebSocketRequestHandler currently implements AjaxRequestTarget.

We can introduce a new interface IPartialPageRequestHandler (or better named), that is implemented by AjaxRequestTarget and WebSocketRequestHandler:

/**
 * Request handler that allows partial updates of the current page instance.
 */
public interface IPartialPageRequestHandler extends IPageRequestHandler
{

	void add(final Component component, final String markupId);
	void add(Component... components);
	void addChildren(MarkupContainer parent, Class<?> childCriteria);
	void appendJavaScript(CharSequence javascript);
	void prependJavaScript(CharSequence javascript);
	void focusComponent(Component component);
	String getLastFocusedElementId();
	Collection<? extends Component> getComponents();
	IHeaderResponse getHeaderResponse();
}

This way it becomes clearer that WebSocketRequestHandler doesn't have anything to do with Ajax.
