chrome 每次访问 tomcat JSESSIONID都会变化不一样，IE浏览器则是相同的，是什么问题导致的

chrome 59.0.3071.115
tomcat tomcat7.0.68
试验代码

    @At("nutznewdemo/home/index")
    @Ok("jsp:jsp.home.index")
    @GET
	public void index(HttpSession session) {
		// dao.query("select 1 from daul", null);
        log.info("HomeModule#index");
		log.infof("session id is : %s", session.getId());
    }
