Ruby 如何阻止sinatra重新写入标题名？

Sinatra对所有标题名称进行驼峰式压缩，导致“P3P”出现问题。代码：

require 'rubygems'
require 'sinatra'

configure :production do
  # Configure stuff here you'll want to
  # only be run at Heroku at boot

  # TIP:  You can get you database information
  #       from ENV['DATABASE_URI'] (see /env route below) 
end

# Quick test
get '/track' do
  #response.headers['Cache-Control'] = 'public, max-age=300'
  response.set_cookie("visited",1)
  response['this-that'] = "CP=\"CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE\""
  response['P3P'] = "CP=\"CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE\""
  "SUCCESS"
end

我如何阻止sinatra重新编写cookie名称。我能做一个猴子补丁吗？

，所以理论上这不应该是个问题–

P3p

应该和

P3p

一样有效

在您的情况下，标题是，而不是Sinatra。更改到另一台服务器，如Thin（它不会更改头）将是最简单的修复方法（使用Thin over Webrick还有其他好处）

如果您真的需要继续使用Webrick，您可以考虑进行修补。您必须小心，因为Webrick会将标题名称降级以处理重复的标题，所以您可能必须对此进行说明
