推荐答案
您可以自定义在vlc_error上投放的综合页面. default.vcl配置文件已经显示了如何通过服务著名的大师冥想"错误页面(啊，那段美好的Amiga日子)来做到这一点.
You can customize the synthetic page being served on a vlc_error. The default.vcl configuration file already shows how to do this, by serving the famous "Guru Meditation" error page (ahh, those wonderful Amiga days).
自定义示例:
sub vcl_error {
set obj.http.Content-Type = "text/html; charset=utf-8";
synthetic {"
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Sorry, server under maintainance - My Website"</title>
<style src="css/style.css"></style>
</head>
<body>
<h1>The server is being updated</h1>
<p>Please check back later. Meanwhile, here's a picture of a rabbit with a pancake on its head:</p>
