怎么用url类实现访问一个页面里面的一个url

[cutemouse]

现在有一个url1 里面有一个url2,请问如何在保持连接的情况下用java通过url1访问rul2,
rul1:http://218.200.160.29/wm/store/renew.do?cid=cid%3A600655001992
url2:href="http://218.200.160.29/wm/store/reright.do?cid=600655001992&pid=1&tokenkey=200803111048330005346&mid=13412345678&did=nokian73&ch=000000&bid=000000

现在用浏览器访问url1,点击(或者右键打开)url2是成功访问;
但是:
用浏览器访问url1,查看代码获取url2,然后开一个新的浏览器访问url2,是失败的.
用java开两个httpUrlConnection先后打开url2和url2,也是失败的.
经过抓包,没有发现任何sessionid和cookie的信息.
请教有没有人知道怎么模拟呢？
谢谢。

应该是
HTTP头中HTTP_REFERER字段的值的问题。通过这个url2可以知道你是从url1过来的(可以用来防止盗链)。
你可以尝试使用url2的setRequestProperty("HTTP_REFERER","http://218.200.160.29");来模拟一下。
如果还是不行-_-!，建议你通过一个代理服务器。
看下通过http://218.200.160.29/wm/store/renew.do?cid=cid%3A600655001992
点击url2的时候发送给服务器的http的报头是什么样子的。

GET /hahaha HTTP/1.1

差得应该就是红色的部分标注的信息

一、成功访问url1和url2的情况
用opera/9.10 连接cmwap
访问url1的头

用WinWAP/3.2访问 连接cmwap

。。。同样是返回成功的页面信息


二、我用java的urlhttpconnetion 访问
访问rul1，的发送数据头。
[2008-3-14 17:11:39:390]
GET http://218.200.160.29/wm/store/renew.do?cid=cid%3A228158 HTTP/1.1

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
。。。访问url1返回的页面和用winwap的一样，是一个同样的wap页面；


第二步新建立一个httpurlconnetion，通过url1返回的页面得到url2，连接url2
[2008-3-14 17:11:42:453]
GET http://218.200.160.29/wm/store/reright.do?cid=228158&pid=4&tokenkey=200803141711580009077&mid=13412345678&did=nokian73&ch=000000&bid=000000 HTTP/1.1

访问rul2返回的是一个失败提示的页面，这个情况和在winwap里面访问时候，从代码里面copy出url2直接在一个新winwap的地址栏目里输入一样是失败提示的wap页面，必须要直接在wap页面上点击才成功。
我又用socket直接连代理服务器，保持一个和代理服务器的tcp连接，两次模拟发送http数据，同样的情况，和用httpurlconnetion两个连接一样，不成功。

哪用这么麻烦啊，你获取了也没有用 真正下载的时候会在下到99%的时候提示下载失败的，
