清漆传递错误的内容

我安装了清漆，并面对我认为是一个主要问题：

有时几个不同的URL显示相同的caching内容。

如果你进入一个显示错误页面内容的页面，并强制刷新（CTRL + F5），那么你直接从后端获得正确的内容。

例如，而不是显示：

• 在Varnish Security中找不到“variables.tcl”文件
• 列出清漆caching的内容
• “服务清漆停止”实际上并不停止清漆
• 从正在运行的Varnish实例中提取configuration
• 根据协议设置清漆后端

有时它caching：

即使使用默认的VCL文件也会发生这种情况。

为什么发生这种情况？

问候，

这是我的清漆configuration文件：

在/ etc / default / varnish中我有：

 DAEMON_OPTS="-a :80 \ -T localhost:6082 \ -f /etc/varnish/magento.vcl \ -S /etc/varnish/secret \ -p send_timeout=6000 \ -s malloc,12G" 

 vcl_recv { ... # Add one of this per vhost, you may want to try set req.http.host = req.http.host; although I haven't tested that if (req.http.host == "example1.com") { set req.http.host = "example1.com"; } if (req.http.host == "example2.com") { set req.http.host = "example2.com"; } ... return(lookup); }
