关于jsp中用全景地图时，会出现flash缓存问题解决方案

<script type="text/javascript">
    var vto =  document.getElementById("vtour").value;
    var vto1 = "../../../static/fileqj/"+vto+"/vtour/tour.xml?v="+Math.random(); //这里记得加个时间戳或者一个随机数
    var vars = {};
    vars["plugin[vtoureditor].keep"] = true;
    embedpano({swf:"../../../static/fileqj/"+vto+"/vtour/tour.swf", xml:vto1, id:"krpanoSWFObject", target:"pano", flash:"auto", html5:"prefer",passQueryParameters:false, vars:vars});
    function resize() {
        var th = document.getElementById("title").clientHeight;

        var ph = (typeof(window.innerHeight) == 'number') ? window.innerHeight : ((document.documentElement && document.documentElement.clientHeight) ?document.documentElement.clientHeight : ((document.body && document.body.clientHeight) ? document.body.clientHeight : 500));
        document.getElementById("pano").style.height = (ph-th)+"px";
    }
    window.onresize = resize;
    resize();
</script>

xml会变更数据，所以一开始引入xml的时候增加一个版本号（时间戳或者随机数），从而达到下次加载的不是已经加载过的相同名的xml而进行重新加载xml；
