我正在运行Magento v2.2.6网上商店，我想在上面使用Varnish。现在，我安装了Varnish，它似乎处于活动状态。但是我有一个（大）问题。
Varnish的工作方式是一旦一个人加载页面/文件，它就会缓存页面。我现在遇到的问题是每个人都再次缓存了页面。 （页面对于每个人/每个人都是唯一的）
因此，如果我在同一设备上两次加载主页，则会缓存该页面。但是，如果我转到手机上的主页，则该页面需要再次缓存。
我非常确定这与网上商店的Cookie有关。由于Magento 2将所有内容保存在一个大cookie中。 而且请求标头是：
cache-control: no-store, no-cache, must-revalidate, max-age=0
我不认为应该是这样。
为了给大家一个更好的主意，这是我现在正在使用的varnish.vcl。这是Magento 2的默认设置，只是它始终显示HIT或MISS。 （.host不同，但是我不打算在此处发布该IP）

我们已经尝试了几乎所有方法，而且应该可以，但不能。

以下 response 标头可以：
cache-control: no-store, no-cache, must-revalidate, max-age=0
那些被发送给最终客户（浏览器）。 Varnish看到不同的Cache-Control值。
VCL没有错。您最有可能在其中一台设备上执行了某些操作（例如，添加到购物车中），这导致了不同的“状态”，随后该设备进入了不同的缓存分区。
要进行干净测试，请使用隐身模式并在每台设备上重新加载页面。

好吧，我发现了问题所在！
由于某种原因，variable User-Agent实现了它，以便Varnish基于用户代理进行缓存。因此，每个人都缓存了不同的Varnish版本。
这显然不是Varnish的重点，因为它只适用于每个人而不是所有人。
因此，删除.htaccess中的“用户代理”即可解决此问题！
我刚刚添加：
SetEnv dont-vary 1
