Node.js ExpressJS仅在第一次加载时发送索引的200状态代码。在那之后的每一次

所以我有一个运行ExpressJS的本地项目，我使用ejs作为我的模板引擎。每当我启动服务器并转到主页时，index.html文件都会正确呈现，但每次后续加载索引都会显示未呈现的index.html文件，状态为304。所有其他页面每次都呈现良好效果。如果我重新启动服务器，在我第一次访问主页时，它会正确呈现，但在每次加载页面之后，仍然会为未呈现的文件提供服务。如果我在路由中设置一个断点（我使用的是WebStorm），我可以第一次到达断点，但再也不会。我想这是因为304。我还有app.disable（'etag'）。非常感谢您的帮助

更新 这是浏览器在收到304状态时将显示的内容
