Css 为什么Expressjs在公共/样式表文件中提供状态为304的样式表？

我发现某些样式表，我可能刚刚用

304

状态代码更新了load。这是我在客户端的代码：

  <link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet"/>
<link href="http://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.2.0/css/font-awesome.min.css"rel="stylesheet"/>
<link href="stylesheets/bootstrap-social.css" rel="stylesheet"/>
<link href="stylesheets/style.css" rel="stylesheet"/>
<link rel="stylesheet" href="stylesheets/divider.min.css"/>

你能告诉我像

compression

这样的模块是否在做这件事吗？

可能是因为有缓存，而且内容没有按照304 http状态通知进行修改。“…我可能刚刚更新了…”嗯，是吗？@Jon我更新了样式表并保存了它。也许可以尝试

npm uninstall compression

，看看这是否修复了它。不难check@Jordan这对我来说很有效，但我也不得不禁用Chrome上的缓存
