主域名 - imagecompressor.io，子域名 - dev.imagecompressor.io
内容配置似乎不适用于子域。对两者均curl返回200 OK，但文件仅针对主域下载。对于子域，请求将转发到 reactjs 前端应用程序。
https://imagecompressor.io/images/Logo.png- 作品
https://dev.imagecompressor.io/images/Logo.png- 不起作用

完全一样。不知道这里的问题是什么。
答案1
这似乎是缓存问题，但清除缓存确实对一些下载有用。根本原因是service worker在子域前端启用了该功能。禁用该功能后问题就解决了。
