Questions about the socket communication GET/HTTP/1.1-CodePudding

In writing the socket multithreaded communication, receiving and sending messages sometimes can appear a puzzling the IP address of the connected, received information is GET/HTTP/1.1, and then lead to connect all broken, could you tell me what this mean,

There are online crawler swept in a WEB page,
As for why lead to connect all disconnected, the problem was on your code,

 UINT server_thd (LPVOID p) 
{
WSADATA WSADATA; 
WORD wVersion; 
WVersion=MAKEWORD (2, 2); 
WSAStartup (wVersion, & amp; WsaData); 

SOCKADDR_IN local_addr; 
SOCKADDR_IN client_addr; 
Int iaddrSize=sizeof (SOCKADDR_IN); 
=(CSocketDemoDlg *) AfxGetApp CSocketDemoDlg * DLG () - & gt; GetMainWnd (); 
Local_addr. Sin_family=AF_INET; 
Local_addr. Sin_port=htons (5150); 
Local_addr. Sin_addr. S_addr=htonl (INADDR_ANY); 

Listen_sock=socket (AF_INET SOCK_STREAM, IPPROTO_TCP); 

Bind (listen_sock, (struct sockaddr *) & amp; Local_addr, sizeof (SOCKADDR_IN)); 

Listen (listen_sock, 50); 
While (1) 
{
The sock=accept (listen_sock, (struct sockaddr *) & amp; Client_addr, & amp; IaddrSize); 
Cstrings port; 
Port. The Format (" % d ", int (ntohs (client_addr. Sin_port))); 
DLG - & gt; The update (" connected from: "+ cstrings (inet_ntoa (client_addr. Sin_addr)) +" port: "+ port); 

CreateThread (NULL, 0, Thread_1, (LPVOID) the sock, 0, NULL);//the new SOCKET to thread 

} 

return 0; 
}

Could you help me have a look at this code has any problem, open program run this thread to listen, listen to create a new thread after the communication,
