Rails 发出警告:“Rack::File headers 参数在 Rack 1.5 之后替换了 cache_control" [英] Rails emits warning: "Rack::File headers parameter replaces cache_control after Rack 1.5"

问题描述

我最近将 Rails 升级到 v3.2.服务器启动并工作，但我注意到以下警告:

I've recently upgraded my Rails to v3.2. The server starts and works, however I'm noticing the following warning:

Rack::File headers parameter replaces cache_control after Rack 1.5.

在我的 development.rb 中，我有以下缓存控制配置:

In my development.rb I have the following configuration for cache control:

config.static_cache_control = "public, max-age=36000"

警告是什么意思，我应该怎么做才能解决?

What does the warning mean and what should I do to address it?

推荐答案

警告是 由从 Rails 内部调用.该警告已在 Rails 3.2.13.

The warning is caused by a call from within Rails itself. The warning has been fixed in Rails 3.2.13.
