I'm implementing a TCP socket server in C and Linux. It will be a chat server handling many requests simultaneously. Here is the pseudo code for how it is setup

```
create a socket
bind to a well-known port
use listen to place in passive mode
while (1)
{
    accept a client connection
    fork
    if (child)
    {
        communicate with new socket
        close new socket
        exit
     }
 else
 {close new socket}
}

```

From what I've seen, the "communicate with new socket" part consists of reading the buffer and then possibly writing to the buffer, then the socket closes. I thought sockets were suppose to be a persistent connection? If the client has to reconnect every time it wants to send more data to the server, isn't this inefficient and defeating the purpose of sockets?
