使用Google Canary解析.

Resolved using google canary.

使用canary，如果我将内容直接重定向到我的三个上游服务器之一，它将起作用. 如果我重定向到上游名称(即CDN-音频(或视频))，浏览器将无法解析名称.

With canary, it works if i redirect content directly to one of my three upstream server. If i redirect to upstream name (i.e. cdn-audio(or video)) the browser cannot resolve name.

我听说过Nginx的lua-upstream-module，有人可以帮我吗?

I've heard about lua-upstream-module for nginx, can someone help me?
