Simple HTTP server on Linux C++ sockets - c++

Question

I try to write simple linux app that will accept http requests. I want to be able to stop listening thread so I use select().
Call sequence is
socket()->setsockopt()->bind()->listen()->select()->accept()->read()
When I send request from Chrome I get 451 bytes long buffer. Then select() immediately returns with success as well as accept() as if another request came. And then `read()' stops the thread waiting, because it has nothing to read.
socket() ok. listenSocket:3
bind() ok
listen() ok
select() got ready connection
accept() ok. socket: 4
reading...
read() ok. NRead: 451
listen() ok
select() got ready connection
accept() ok. socket: 5
reading...
What I do wrong?
What articles/books are worth to read to learn socket programming?
Best wishes,
Yura
Here is the simplified code:
void doServer()
{
const int trueFlag = 1;
m_socketListen = socket(AF_INET, SOCK_STREAM, 0);
// check m_socketListen
nRetVal = setsockopt(m_socketListen, SOL_SOCKET, SO_REUSEADDR, &trueFlag, sizeof(int));
// check
struct sockaddr_in addrServer;
bzero((char*)&addrServer, sizeof(addrServer));
addrServer.sin_family = AF_INET;
addrServer.sin_port = htons(DEFAULT_HTTP_PORT);
addrServer.sin_addr.s_addr = INADDR_ANY;
nRetVal = bind(m_socketListen, (const struct sockaddr* )&addrServer, sizeof(addrServer));
// check
struct sockaddr_in addrClient;
while (true)
{
bzero((char*)&addrClient, sizeof(addrClient));
unsigned int addrSize = sizeof(addrClient);
nRetVal = listen(m_socketListen, SOMAXCONN);
// check
struct timeval timeout;
timeout.tv_sec = 5;
timeout.tv_usec = 0;
fd_set set;
FD_ZERO (&set);
FD_SET (m_socketListen, &set);
nRetVal = select (FD_SETSIZE, &set, NULL, NULL, &timeout);
// check
if (FD_ISSET(m_socketListen, &set))
{
int clientSocket = accept(m_socketListen,
(struct sockaddr*)&addrClient,
&addrSize);
int NRead;
char buffer[BUF_SIZE];
bzero(&buffer, BUF_SIZE);
NRead = read(clientSocket, &buffer, BUF_SIZE);
std::cout << "read() ok. NRead: " << NRead << std::endl;
}
}
}
