Developing concurrent TCP servers

This section teaches you a pattern for developing concurrent TCP servers, which are servers that use separate goroutines to serve their clients following a successful Accept() call. Therefore, such servers can serve multiple TCP clients at the same time. This is how real-world production servers and services are implemented.

The code of concTCP.go is as follows:

package main
import (
    "bufio"
    "fmt"
    "net"
    "os"
    "strconv"
    "strings"
)
var count = 0
func handleConnection(c net.Conn, myCount int) {
    fmt.Print(".")

The previous statement is not required—it just informs us that a new client has been connected.

    netData, err := bufio.NewReader(c).ReadString('\n')
    if err != nil {
        fmt.Println(err)
        return
    }
    for {
     
        temp := strings.TrimSpace(string(netData))
        if temp == "STOP&quot...
