Forwarding data as TCP Client - c

Question

I have a client requesting data (DA) from server A, and then I need to send DA to a second server B. I got it while the data is not larger than the buffer. However the following is not working for passing all data from A to B. I notice that when I create the socket_fwd and connect after closing the first sockfd, it works. But since I need to forward all data, I need to process all incomming as soon as it arrives
int sockfd, sockfd_fwd, n, n_fwd;
gint BUFFER=900;
char buf[BUFFER];
char* addr = "11.0.0.20"; //Server A listening on port 80
struct sockaddr_in server_addr = {0};
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(80);
char chunk[BUFFER];
gint nfw;
gint total_recv = 0;
gint total_fwd = 0;
struct sockaddr_in server_addr2 = {0};
server_addr2.sin_port = htons(5555);
server_addr2.sin_family = AF_INET;
char *addr2 = "127.0.0.1"; //Server B listening on port 555
//#################Request data from A:80 ###########################
if(inet_pton(AF_INET, addr, &server_addr.sin_addr) != 1){
perror("inet_pton");
return -1;
}
sockfd = socket(AF_INET, (SOCK_STREAM), 0); //socket with server A
if (connect(sockfd, (struct sockaddr*)&server_addr, sizeof(server_addr)) < 0)
mylog(G_LOG_LEVEL_MESSAGE, __FUNCTION__,"Error on connect");
send(sockfd, buffer, strlen(buffer), 0); //Buffer contains something like get xx Kib to the server
bzero(buffer, BUFFER);
if(inet_pton(AF_INET, addr2, &server_addr2.sin_addr) != 1){
mylog(G_LOG_LEVEL_MESSAGE, __FUNCTION__,"Error inet pton");
return -1;
}
if(inet_pton(AF_INET, addr2, &server_addr2.sin_addr) != 1){
perror("inet_pton");
return -1;
}
sockfd_fwd = socket(AF_INET, (SOCK_STREAM), 0); //socket with server B
if (connect(sockfd_fwd, (struct sockaddr*)&server_addr2, sizeof(server_addr2)) < 0)
mylog(G_LOG_LEVEL_MESSAGE, __FUNCTION__,"Error on connect");
while ((n = recv(sockfd, chunk, BUFFER, 0)) > 0) {
total_recv += n;
mylog(G_LOG_LEVEL_MESSAGE, __FUNCTION__,"Recv chunk %s num-bytes:%i",chunk,total_recv);
nfw = send(sockfd_fwd, chunk ,n, 0);
memset(chunk,0,BUFFER);
}
close(sockfd);
close(sockfd_fwd);
