手机访问实现无缝跳转怎么实现？

 <!---识别手机或电脑的js开始--->
<script language="javascript">
(function(){
    var res = GetRequest();
    var par = res['index'];
    if(par!='gfan'){
        var ua=navigator.userAgent.toLowerCase();
        var contains=function (a, b){
            if(a.indexOf(b)!=-1){return true;}
        };
//将下面的http://m.diandazuoye.com改成你的wap手机版地址
        var toMobileVertion = function(){
            window.location.href = 'http://m.abc.com'
        }

        if(contains(ua,"ipad")||(contains(ua,"rv:1.2.3.4"))||(contains(ua,"0.0.0.0"))||(contains(ua,"8.0.552.237"))){return false}
        if((contains(ua,"android") && contains(ua,"mobile"))||(contains(ua,"android") && contains(ua,"mozilla")) ||(contains(ua,"android") && contains(ua,"opera"))
    ||contains(ua,"ucweb7")||contains(ua,"iphone")){toMobileVertion();}
    }
})();
function GetRequest() {
   var url = location.search; //获取url中"/"符后的字串
   var theRequest = new Object();
   if (url.indexOf("/") != -1) {
      var str = url.substr(1);
      strs = str.split("/");
      for(var i = 0; i < strs.length; i ++) {
         theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
      }
   }
   return theRequest;
}
</script>
<!---识别手机或电脑的js结束--->

是这样的，上面的代码，能够识别手机访问, 如果手机访问http://www.abc.com,
现在能够实现跳转到m.abc.com

现在问题是怎么实现访问http://www.abc.com/cde/123.html 跳转到http://m.abc.com/cde/123.html

解决方案

要无缝跳转，就写在服务器上，写在js上肯定不能无缝
