Preserve RequestHeaders

[danazkari]

Hi, I'm using this project to redirect requests in an existing heroku app that has been moved to a more powerful cluster.

Redirects occur fine but I need one of the headers that the devices are sending to heroku, to be sent to the cluster where the proxy is pointing at.

(I'm not a ruby dev so please bear with me)

config.ru (if it helps)

require 'rack/reverse_proxy'

use Rack::ReverseProxy do
  reverse_proxy_options :preserve_host => true
  reverse_proxy '/', 'http://example.com'
end

app = proc do |env|
  [ 200, {'Content-Type' => 'application/json'}, "b" ]
end

run app
