不处理 ESI 的清漆包括 [英] Varnish not processing ESI includes

问题描述

我正在尝试设置 Varnish 以在本地环境中处理 ESI 包含.

I'm trying to setup Varnish to process ESI includes on a local environment.

我在虚拟机中运行 varnish，内容在主机上运行.

I am running varnish in a virtual machine and the content is running on the host machine.

我有两个文件index.html"和test.html".它们都存储在 apache 服务器的 docroot 中名为esi"的文件夹中.

I have two files "index.html" and "test.html". These are both stored in a folder called "esi" in the docroot of an apache server.

index.html

<h1>It Works!</h1>
<esi:include src="test.html" /> 

test.html

<p>ESI HAS BEEN INCLUDED</p>

Varnish 在 8000 端口的虚拟机上运行.所以我在这里访问它:http://192.168.56.101:8000/esi/

Varnish is running on the virtual machine on port 8000. So I access it here: http://192.168.56.101:8000/esi/

在虚拟机上的/etc/varnish/default.vcl 中，我将以下配置添加到文件底部:

in /etc/varnish/default.vcl on the virtual machine I have added the followin config to the bottom of the file:

sub vcl_fetch {
   set beresp.do_esi = true; /* Do ESI processing               */
   set beresp.ttl = 24 h;    /* Sets the TTL on the HTML above  */
}

认为它应该处理所有请求的 ESI(不要在意它是否只是试图让这个东西工作的坏习惯:))

With the idea that it should process ESI on ALL requests (Dont care if its bad practice just trying to get this thing to work :))

加载 http://192.168.56.101:8000/esi/ 时的结果是:

<h1>It Works!</h1>
<esi:include src="test.html" />

即.ESI 显示在标记中，它没有被处理.

ie. the ESI is shown in the markup, it is not being processed.

我检查了 Varnish 日志，但是那里没有错误，也没有与 ESI 相关的内容.

I have checked the Varnish log, however there are no errors in there and nothing related to ESIs.

谁能看到我在这里做错了什么?如果需要更多信息，请告诉我..谢谢

Can anyone see what I am doing wrong here? Let me know if more information is needed.. thanks

推荐答案

如果您的 esi 包含 src 是test.html"，那么 varnish 会将该请求发送到您的默认后端，即 127.0.0.1.我相信您需要为远程服务器配置第二个后端.像这样:

If your esi include src is "test.html" then varnish will be sending that request to your default backend, which is 127.0.0.1. I believe you need to configure a second backend for your remote server. Something like this:

backend default {
    .host = "127.0.0.1";
    .port = "8000";
}

backend hostmachine {
    .host = "50.18.104.129"; # Enter your IP address here
    .port = "80";
}

然后在您的子 vcl_recv 中，您需要将 URL 中包含/esi/的流量重定向到远程服务器.

Then in your sub vcl_recv you need to redirect traffic that has /esi/ in the URL to the remote server.

sub vcl_recv {
      if (req.url ~ "^/esi/") {
            set req.backend = hostmachine;
            set req.http.host = "www.correctdomainname.com";
      } else {
            set req.backend = default;
      }
}

我现在正在做同样的事情，所以试一试，让我知道它是否适合你.

I'm working on the same thing right now so give it a try and let me know if it works for you.
