A collection of monkey patches I use when debugging with Charles. They force various http clients to use the `http_proxy` env variable as a proxy. You shouldn't actually add these to your project.

net_http_auto_proxy_monkey.rb

class Net::HTTP
  def proxy?
    !!_env_proxy_uri
  end

  def proxy_address
    _proxy_uri_from_env.host
  end

  def proxy_port
    _proxy_uri_from_env.port
  end

  def _proxy_uri_from_env
    URI(ENV['http_proxy'])
  rescue
    nil
  end
end
