我想获得这个页面上的的部分信息如下：
| CN | F | 200810042683 A | (Patent of invention) | |
| PRS Date : | 2009/05/20 | |||
| PRS Code : | C06 | |||
| Code Expl.: | + PUBLICATION | |||
 |
||||
|
|
|
|
|
| PRS Date : | 2009/07/15 | |||
| PRS Code : | C10 | |||
| Code Expl.: | REQUEST OF EXAMINATION AS TO SUBSTANCE | |||
|
||||
但是，这个页面总共向服务器发送了两次请求，（我用firefox的插件firebug捕获到的），第一个请求用Httpwebrequest可以很轻松得到，但是第二个很难，怎么搞都得不到正确的响应：

请求二：

但是对于第二个请求，我怎么模拟都不能够得到正确的响应。
还望高手赐教。
谢谢。
问题补充：
用fiddler捕获的请求二的内容：
