请教http协议高手，小弟我c语言写一个表单提交的程序，浏览器表单提交和c程序发送的数据一模一样，但结果却不一样！

请问http协议高手，我c语言写一个表单提交的程序，浏览器表单提交和c程序发送的数据一模一样，但结果却不一样！！
我用抓包工具分析测试，发现用浏览器表单提交和c程序发送的数据一模一样，而浏览器能接收到应答，而c程序确一直阻塞于套接字的读过程，根本没有应答，代码如下：

#include "stdio.h"
#include "stdlib.h"
#include "winsock2.h"
#pragma comment(lib,"ws2_32.lib")
int main(int argc, char* argv[])
{

  SOCKET hsocket;
  SOCKADDR_IN saServer;
  WSADATA wsadata;
  LPHOSTENT lphostent;
  int nRet;
  char* host_name="**.**.**.**";
  char* reqHead="GET /test/proc8.jsp?cardno=9175880000000051&action=3 HTTP/1.1\r\n"
  "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint, */*\r\n"
  "Referer: http://**.**.**.**:8088/test/pay.jsp\r\n"
  "Accept-Language: zh-cn\r\n"
  "Accept-Encoding: gzip, deflate\r\n"
  "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)\r\n"
  "Host: **.**.**.**:8088\r\n"
  "Connection: Keep-Alive\r\n"
  "Cookie: JSESSIONID=A55DFDF6FE50070D841925B49D425BB2\r\n";
 // 初始化套接字
  if(WSAStartup(MAKEWORD(2,2),&wsadata))
  printf("初始化SOCKET出错！");
  lphostent=gethostbyname(host_name);
  if(lphostent==NULL)
  printf("lphostent为空！");
  hsocket = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
  saServer.sin_family = AF_INET;
  saServer.sin_port = htons(8088);
  saServer.sin_addr = *((LPIN_ADDR)*lphostent->h_addr_list);
  // 利用SOCKET连接 FineReader
  nRet = connect(hsocket,(LPSOCKADDR)&saServer,sizeof(SOCKADDR_IN));
  if(nRet == SOCKET_ERROR)
  {
  printf("建立连接时出错！");
  closesocket(hsocket);
  return 0;
  }
  // 利用SOCKET发送  

  nRet = send(hsocket,reqHead,strlen(reqHead),0);
  if(nRet==SOCKET_ERROR)
  {
  printf("发送数据包时出错！");
  closesocket(hsocket);
  }
  char Dest[3000];
  nRet=1;
  while(nRet>0)
  {
  // 接收返回数据包
  nRet=recv(hsocket,(LPSTR)Dest,sizeof(Dest),0);
printf("nRet is:%d\n");
  if(nRet>0)
  Dest[nRet]=0;
  else
  Dest[0]=0;
  // 显示返回数据包的大小、内容
  printf("\nReceived bytes:%d\n",nRet);
  printf("Result:\n%s",Dest);
  }
 
  return 0;
}


[解决办法]
"Connection: Keep-Alive\r\n"
"Cookie: JSESSIONID=A55DFDF6FE50070D841925B49D425BB2\r\n";

改成

"Connection: Close\r\n"
"Cookie: JSESSIONID=A55DFDF6FE50070D841925B49D425BB2\r\n\r\n";
