To make the propgress.html work well you should make server load the html .
<!DOCTYPE html>
<html lang="ch">

<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div>
<progress id="progressBar" value="0" max="100" style="width: 300px;"></progress>

golang test udp socket buffer after set it value.
package main
import (
"fmt"
"net"
// "os"
"syscall"
)
const (
the function the follow utility:
1. inquire socket buffer before set socket buffer
2. set socket buffer
3. get the info after set buffer
conclusion: a. the get value of socket buffer is double of the set value.
b. if set value > the max of os max value , the value we get is double *maxsocketbuffer of os
for example
if max of os socket buffer is 200000 bytes and we set value is 3000000 ,
then we get the value is 400000 not 600000.
