587d8249367417b2b2512c3e	2	301576	使用 helment.noCache() 禁用客户端缓存

Description

请注意，本项目在这个 Repl.it 项目的基础上进行开发。你也可以从 GitHub 上克隆。如果你为你的网站发布了一个更新，此时你一定想要用户看到最新的版本。为此，你可以通过禁用浏览器缓存来实现。而且，这个功能在开发环境中也非常有用。但另一方面，缓存可以为你的网站带来性能方面的提升，因此你应该只在必要的时候禁用缓存。

Instructions

Tests

tests:
  - text: 应正确加载 helmet.noCache() 中间件
