如何自定义＆＃39; 503后端提取失败＆＃39;清漆4？

我在通过合成阶段时自定义其他错误：

sub vcl_synth {
    if (resp.status == 750) {
        set resp.http.location = "http://mobile.cronica.com.ar/";
        set resp.status = 302;
        set resp.http.Action = "Redirect";  
        return(deliver);
    }
    if (resp.status == 751) {
        set resp.status = 301;
        set resp.http.location = "http://www." + req.http.host + req.url;
        set resp.http.Action = "Redirect";
        return(deliver);
    }
    else {
         synthetic( {"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
  <head>
    <title>"} + resp.status + " " + resp.reason + {"</title>
    <link href='http://fonts.googleapis.com/css?family=Oswald:400,700' rel='stylesheet' type='text/css'>

  </head>
  <body style="background-color:#444; font-family: 'Oswald', sans-serif;">
    <h1 style="color:#DD8363;">Error "} + resp.status + " " + {"</h1>
    <p style="color:#5F88C4; ">"} + resp.reason + {"</p>
    <h3 style="color:white;">CEPI Says</h3>
    <p style="color:#bdb76b;">XID: "} + req.xid + {"</p>
    <p style="color:#bdb76b;">Edge-Server: "} + server.hostname + {"</p>
    <hr>
    <p style="color:#65b042;">2.0</p>
  </body>
</html>
"} ); 
        return(deliver);
    }

}

但503错误似乎避免了这一点。

根据backend_error()控制vcl_synth()之后应该传递给sub vcl_backend_error { return(retry); }，但实际上您看到的错误页面是Varnish Processing States无条件传递的。您可以在那里自定义网页，也可以在vcl中添加vcl_synth()以强制跳转到resp.status = 503 {{1}}。
