我有一个启用 Magento 2.2.2 Varnish 的网站
基于基于用户代理检测设备的php代码段，我在桌面和“移动”中打印“IN Desktop”
在移动设备中。
但是一旦页面被缓存，它就会在桌面和移动设备上打印“IN Desktop”
实际结果应该像“在桌面”应该打印在桌面和“在移动”应该在移动中提供
是否有可能根据用户代理生成不同的缓存

最佳答案
您需要确保 Varnish 将移动页面和桌面页面视为不同的东西。这是通过使用 Vary: 来实现的。标题。
您应该使用 devicedetect而不是在 PHP 代码中检测设备。
您需要做的就是实现sending the detected device type to Magento .此代码段负责按设备类以及设备类检测来处理不同的缓存。
现在，在 Magento 中，您可以删除您的设备检测代码，只需依赖 HTTP header X-UA-Device 的值即可。 .它将具有 pc 的任一值, mobile-smartphone , mobile-generic , bot或 tablet-microsoft .
