::

    if ( $http_user_agent ~ iPhone ) {
       rewrite ^.*$ http://ios.747.cn redirect;
    } 

php代码::

    $agent = $_SERVER['HTTP_USER_AGENT'];
    if(strpos($agent,"NetFront") || strpos($agent,"iPhone")
       || strpos($agent,"MIDP-2.0") || strpos($agent,"Opera Mini")
       || strpos($agent,"UCWEB") || strpos($agent,"Android")
       || strpos($agent,"Windows CE") || strpos($agent,"SymbianOS"))
    header("Location:http://online.747.cn/747/");

用wap上网::

    if(strstr($_SERVER['HTTP_ACCEPT'],'vnd.wap'))
    {
        header("Location:http://m.747.cn/x");
    }



用于打开portal页面的打开页面::


    // 可以使用baidu(因为是动态页面), 但m.747.cn是静态页面
    // 当然如果使用浏览器,可能也可以打开这个页面,但那是因浏览器内部做了操作
    location ~ /?timestamp=d+ {
        rewrite ^(/timestamp=d+)$ http://m.747.cn/ permanent;
    }
