添加移动检测清漆{default.vcl}后，清漆不启动

Question

我有一个基本的default.vcl为我的网站，它工作。

我添加了下面的代码来检测并为用户提供不同的主题，如果来自PC或手机。添加下面的代码来检测移动设备后，清漆不会启动。

如何解决这个问题，从而清漆检测到移动设备，因此，如果从手机访问移动主题是在同一个URL提供服务，表

     .host = "xx.xx.xx.xx";

，你可以尝试使用启动清漆

varnishd -F -f /etc/varnish/default.vcl 

所以你可以看到所有的消息/错误。顺便说一句：你包括一个devicedetect.vcl。没有这个文件，很难说出了什么问题;）
