nginx – 当网址被点击时找不到404页面,但是当从索引页面上的链

我正在使用带有redis的nginx-lua模块来提供ember-app的静态文件.索引文件内容存储在redis中,作为当(根)域/ IP被命中时由nginx正确提供的值.

如果登录页面是从链接打开的,则会正确打开.但是当通过点击url栏或刷新页面直接打开时,nginx会找不到404.
索引文件是redis,其余文件是从CDN上存在的已编译的js提供的.
以下是nginx配置

                local red = redis:new()

                local ok,err = red:connect("127.0.0.1",6379)
                if not ok then
                    ngx.say("failed to connect: ",err)
                    return
