def on_complete(env)
  raw_cookie = env[:response_headers][SET_COOKIE_HEADER]
  return unless raw_cookie

  tepid_cookie = raw_cookie.split(Xolo::SEMICOLON_SEP_RE)
  tepid_cookie.each do |part|
    name, value = part.split('=')
    case name
    when SESSION_COOKIE_NAME
      self.class.session_cookie = value
    when SESSION_COOKIE_EXPIRES_NAME
      self.class.session_expires = Time.parse(value).localtime
    end
  end
end

#on_request(env) ⇒ Object

we only send back the rack.session cookie, as long as it exists and hasn’t expired (it lasts an hour)
