Nginx 使用Ngnix和3scale缓存不起作用

我使用的是带有默认配置表单3scale的ngnix openreg，并添加了一些内容。无论我做什么，我都会在日志中丢失所有缓存

来自上游服务器的标头：

HTTP/1.1 200
  Content-Length: 1517
  Content-Type: application/xml
  Date: Thu,  6 Oct 2016 11:03:56 UTC
  Expires: Thu,  6 Oct 2016 11:04:11 UTC
  Cache-Control: max-age=15
Length: 1517 (1.5K) [application/xml]

Nginx配置文件：

# user user group;

我刚刚尝试使用相同的缓存设置运行一个配置，它似乎按照预期工作，它在访问日志中打印未命中、命中，然后过期

请随时将完整配置以及您拨打的电话发送给我们support@3scale.net，我们可以看一看：）

干杯
