A very simple rack-proxy in ruby.

The intended of this project is to simplify the implementation of a proxy in Ruby. In order to implement a capable piece of software, it is used the unicorn web server that allows concurrent access.

All the produced code is present in config.ru file. The unicorn.rb file contains the code that allow run the unicorn web server. Notice that the used gem to install the web server is: 'unicorn-rails' and not 'unicorn', because the last have a set of recognized errors.

class AppProxy < Rack::Proxy

  def rewrite_env(env)
    request = Rack::Request.new(env)
    @doc = Nokogiri::XML(request.body.read)
    @doc.remove_namespaces!
    puts @doc

    #Do Something ...
    
    if request.path=='/path1'
      env["HTTP_HOST"] = IP_PORT_DESTINATION_1
    else
      env["HTTP_HOST"] = IP_PORT_DESTINATION_2
    end

    env['rack.input'].rewind
    env
  end
end

post '/*' do
  AppProxy.new.call(request.env)
end

run AppProxy.new

To execute the project use the command as follows:

bundle exec unicorn_rails -p 8090 -c ./unicorn.rb

Have a nice day!
