## 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。某些Web应用程序将提供不受信任的HTML以供下载。默认情况下,某些版本的Internet Explorer会在您的站点上下文中打开这些HTML文件。这意味着不受信任的HTML页面可能会在您的页面上下文中开始做坏事。此中间件将X-Download-Options标头设置为noopen。这将阻止IE用户在受信任站点的上下文中执行下载。 </section>
