C# HttpWebRequest 登录网页问题
现在已经能登录进去了，但是有一步重要操作，不知道该怎么弄！各位帮帮忙

截获的请求标头 如下：

POST /sd_manage/axisqb.do?method=ProxyRecv&pType=1&uuid=1d1ff5194c234306ba3a5a1005e6fb85 HTTP/1.1
Accept: */*
Accept-Language: zh-cn
Referer: http://xxxxxx.net/sd_manage/ford.jsp?ty=ty&zzjphonepwd=132428
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)

Content-Length: 0
Connection: Keep-Alive
Cache-Control: no-cache
Cookie: sidi_sessionid=F7005EEAE3D47D74500704FB57DA21A6

响应标头如下：

HTTP/1.1 200 OK

Server: Apache
Pragma: No-cache
Cache-Control: no-cache

Vary: Accept-Encoding
Content-Encoding: gzip
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html;charset=utf-8

响应正文如下：
{"res":1,"axisres":1,"msg":"鍒掓嫧鎴愬姛l"}


我用 HttpWebRequest 进行操作的时候，老是返回

{"res":"no"}

不知道什么情况！
也不知道！这个到底时候Post请求 还是Get 
/sd_manage/axisqb.do?method=ProxyRecv&pType=1&uuid=1d1ff5194c234306ba3a5a1005e6fb85


------解决方案--------------------
ajax也是请求，你的程序去请求ajax的请求地址
