You allocate the receive buffer once for the connection and then reuse it for the whole lifetime. There is a security concern here; you'd better be sure to flush the buffers correctly or you could cause memory to leak between sessions. If I were writing a server to handle a sensitive task such as executing payment transactions I'd probably take the less memory efficient approach of allocating a new buffer for every connection to lower the risk of data spilling between connections.
