I hope to use a Socket to a Web server to send request, and then obtain Web server respond to my data. But in the response data inside, there is always a response head, how should I get rid of the response head. I tried by the response data length to intercept head off response head data, but I failed, because of different response, data different lengths. How should I do?

#include <stdio.h>
#include <winsock2.h>
#pragma comment(lib,"WS2_32")

//package the http head message ,
void PacketSocket(const char *host,const char *url,const char *data,char *reBuf)
{
//write the string to reBuf
wsprintf(reBuf,"POST %s HTTP/1.1\r\nAccept:text/html\r\nAccept-Language:zh-cn,en\r\nAccept-Encoding:gzip,deflate\r\nContent-type:application/x-www-form-urlencoded\r\nAccept-Charset:GBK\r\nHost:%s\r\nContent-Length:%d\r\nContent-Encoding:utf-8\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; (R1 1.3))\r\nConnection:Keep-Alive\r\nSet-Cookie:JSESSIONID=193F85DD5F193A5714CBC5246218ECO3\r\n\r\n%s",url,host,strlen(data),data);
}

int main(){

WSADATA wsa;
WORD version=MAKEWORD(1,1);

//start up the WSASocket
if(WSAStartup(version,&amp;wsa)==SOCKET\_ERROR){
	printf("start error!");
	return -1;
}


SOCKET s;

//server address
sockaddr\_in addr;


s=socket(AF\_INET,SOCK\_STREAM,IPPROTO\_TCP);
if(s==INVALID\_SOCKET)
{
	printf("has a error,the code:%d",GetLastError());
	return -1;
}

//I  have established a J2EE WEB server, and  then start it,
//use the socket to send request to get index.jsp page
addr.sin\_addr.S\_un.S\_addr=inet\_addr("127.0.0.1");
addr.sin\_port=htons(8080);//the port is 8080  --j2ee web server
addr.sin\_family=AF\_INET;

//connection  the server
if(connect(s,(sockaddr\*)&amp;addr,sizeof(addr))==SOCKET\_ERROR){
	printf("connect had an error!");
	return -1;
}
char szData\[1024\];//request data 

//Encapsulation request message,I've built a socket j2ee project
PacketSocket("localhost","/socket/index.jsp","start=0&amp;limit=15",szData);

if(send(s,szData,strlen(szData),0)==SOCKET\_ERROR){ //To the server sends request
	printf("send request had an error!");
	return -1;
}
char szRecv\[1024\];//Receiving the return value

int nCount=recv(s,szRecv,1024,0);
if(nCount&gt;0)
{
	szRecv\[nCount\]='\\0';
	printf("%s",szRecv);
}

WSACleanup();
return 0;

}

Response data as follows HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Set-Cookie: JSESSIONID=0910F038DEBB2C62C41C
