java httpclient访问asp.net的网站,取不到cookie

Question

最近需要做一个抓取的功能
http://17track.net/Index.htmlRB373021971HK里边的查询是通过ajax查询的
使用浏览器访问http://17track.net/Index.html的时候,使用httpwatch看不到是何时获取到cookie的,只看到一会就sent cookie了,没有看到received cookie.不知道有没有人遇到这样的事情?
使用httpclient访问http://17track.net/Index.html这个地址也是没有获取到cookie.

headers.add(new Header("Accept-Charset","GB2312,utf-8;q=0.7,*;q=0.7"));
headers.add(new Header("Connection","Keep-Alive"));

client.getHostConfiguration().getParams().setParameter("http.default-headers", headers);    GetMethod method2 = new GetMethod("http://17track.net/Index.html");
method2.getParams().setCookiePolicy(CookiePolicy.DEFAULT); 
try {
System.out.println(client.executeMethod(method2));
//System.out.println(method2.getResponseBodyAsString());
System.out.println(client.getState().getCookies().length);
} catch (HttpException e) {

e.printStackTrace();
} catch (IOException e) {

e.printStackTrace();
}

HttpClient httpClient = new DefaultHttpClient();   
        HttpClientParams.setCookiePolicy(httpClient.getParams(), CookiePolicy.BROWSER_COMPATIBILITY);     
        HttpHost httpHost = new HttpHost("localhost");   
        HttpGet httpGet = new HttpGet("/https/");   
           
        HttpResponse response = httpClient.execute(httpHost,httpGet);   
           
        if(HttpStatus.SC_OK==response.getStatusLine().getStatusCode()){   
            //请求成功   
            //取得请求内容   
            HttpEntity entity = response.getEntity();   
            //显示内容   
            if (entity != null) {   
                // 显示结果   
                System.out.println(EntityUtils.toString(entity,"utf-8"));   
            }   
        }   
        //模拟写cookie   
        httpGet = new HttpGet("/https/index.jsp?cookie=write");   
        response = httpClient.execute(httpHost,httpGet);   
        FileWriter fw = new FileWriter("C:/cookie.txt");    
        //读取cookie并保存文件   
        List<Cookie> cookies = ((AbstractHttpClient) httpClient).getCookieStore().getCookies();     
        if (cookies.isEmpty()) {     
            System.out.println("None");     
        } else {     
            for (int i = 0; i < cookies.size(); i++) {   
                System.out.println("- " + cookies.get(i).toString());   
                fw.write(cookies.get(i).toString()+"\r\n");    
            }     
        }   
        fw.close();   
          
        if(HttpStatus.SC_OK==response.getStatusLine().getStatusCode()){   
            //请求成功   
            //取得请求内容   
            HttpEntity entity = response.getEntity();   
            //显示内容   
            if (entity != null) {   
                // 显示结果   
                System.out.println(EntityUtils.toString(entity,"utf-8"));   
            }
