所有已实现的接口：

HttpServletResponse, ServletResponse

public class ServletResponseWrapperInclude
extends HttpServletResponseWrapper

ServletResponseWrapper used by the JSP 'include' action. This wrapper response object is passed to RequestDispatcher.include(), so that the output of the included resource is appended to that of the including page.
