请问怎么获取网址

http://s.click.taobao.com/t?e=zGU34CA7K%2BPkqB07S4%2FK0CFcRfH0GoT805sipKj3WFgObCOjeMxxCTFxN6Vm7j4ewiKkN9jps1h0xwpsosUSBTJl%2Bsn9DQ1mMZl%2BUXg0Gj6BRg%3D%3D

打开以上的淘宝客链接，会经过跳转，最后跳到以下的链接，在asp.net里怎么取得这个链接地址

http://detail.tmall.com/item.htm?id=12730886528&ali_trackid=2:mm_26282330_0_0:1365997719_410_699961681

[解决办法]
看了一下，不是JS中转，就是 Response中头信息的Locatoin
[解决办法]

            var request = HttpWebRequest.Create("http://s.click.taobao.com/t?e=zGU34CA7K%2BPkqB07S4%2FK0CFcRfH0GoT805sipKj3WFgObCOjeMxxCTFxN6Vm7j4ewiKkN9jps1h0xwpsosUSBTJl%2Bsn9DQ1mMZl%2BUXg0Gj6BRg%3D%3D");
            var response = request.GetResponse();
            var url = response.Headers["Location"];

脚本就是不好弄,要通用可以模拟弄个浏览器
要简单一点,如果是这个固定模式,可以用C#替换他脚本中的方法
