我们使用的是Nginx 1.6.2 + Passenger 5.0.6，并且有一个用PHP-FPM定义的虚拟主机，它提供了一个MODx安装。 只有一个位置/ sinatraapp使用Ruby 2.1.1服务Sinatra应用程序。
设置如下，工作相当好，但我们遇到了一个奇怪的问题。 在向Referer发送请求时，nginx响应403 Forbidden，而Sinatra App / Passenger发回302（302redirect在这种情况下是正确的响应！）。 在没有引用者的情况下执行请求时，它按预期工作。
不起作用：
curl -H "Referer: https://www.example.org" https://example.com/sinatraapp 工作：
curl -H "Referer: -" https://example.com/sinatraapp
而将Referer-Header完全离开也是可行的。 Sinatra应用程序将302用户到一个MODx subsite example.com/de/something。

我能够通过设置来解决这个问题
more_set_input_headers 'Referer: -';
在乘客/ sinatraapp位置，但我不知道为什么会发生这个错误。
