## Description
|
|||
|
<section id="description">提醒一下,这个项目是基于<a href="https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-infosec/">Glitch</a>的以下入门项目构建的,或者是从<a href="https://github.com/freeCodeCamp/boilerplate-infosec/">GitHub</a>克隆的。如果您要为您的网站发布更新,并且您希望用户始终下载较新的版本,您可以(尝试)在客户端的浏览器上禁用缓存。它在开发中也很有用。缓存具有性能优势,您将失去这些优势,因此只有在真正需要时才使用此选项。 </section>
