If I understand correctly, you want fetch() to get each URL twice but
you only read from the 'ch' chann
I try writing the program and run it. the program is as following:
package main
import (
"fmt"
"io"
"io/ioutil"
"net/http"
"os"
"time"
)
func main() {
start := time.Now()
ch := make(chan string)
for _, url := range os.Args[1:] {
go fetch(url, ch)
