清漆：vcl_error 重定向

  • 772

我有几个关于 Varnish 配置的问题。我有这个简单的配置文件：

backend default {
  .host = "127.0.0.1";
  .port = "80";
}

sub vcl_recv {

if (req.http.Host == "192.168.1.100")
  {
    set req.http.Location = "http://example.com" req.url;
    error 750 "Permanently moved - TEST";
  }
}

sub vcl_error {

if (obj.status == 750) {
  set obj.http.Location = req.http.Location;
  set obj.status = 301;
  return(deliver);
 }
}

问题：

（1）我遵循了这个例子：set req.http.Location = "http://example.com" + req.url;- 但是我无法重新加载清漆，除非我删除这个+符号 - 它是必需的，它的目的是什么？

    在 2.1 中，字符串连接看起来像这样：

    set req.http.Location = "http://example.com" req.url;

    在 3.0 中，这是使用“+”明确完成的。
