我收到了一个400 Bad Request请求头或cookie太大，从nginx与我的Rails应用程序。重新启动浏览器修复了这个问题。我只在我的cookie中存储了一个字符串id，所以它应该很小。
我在哪里可以找到nginx错误日志？我看了nano/opt/nginx/logs/error.log，但它没有任何相关内容。
我试着设置以下和没有运气：

location / {
    large_client_header_buffers  4 32k;
    proxy_buffer_size  32k;
}

这是我在Firebug中存储cookie的代码和cookie的屏幕截图。我使用Firebug检查存储的会话，我发现New Relic和jQuery也存储cookie;这可能是cookie大小超过的原因吗？
x1c 0d1x的数据

def current_company
  return if current_user.nil?
  session[:current_company_id] = current_user.companies.first.id if session[:current_company_id].blank?
    @current_company ||= Company.find(session[:current_company_id])
end
