我正在使用清漆来加快客户的网站加载时间。我对页面上的图像有问题。页面上的图像不会显示在页面上。这是我按 Ctrl+f5 时的 chrome 输出标题：

问题是图像没有显示在页面上，但它显示在chrome开发人员面板的预览部分中。此外，如果我在浏览器中的新选项卡中打开图像，它会正确显示。清漆版本是4.0.4。Web服务器是Apache 2.2。
编辑：当我通过清漆加载页面时，我在控制台选项卡(chrome(上出现以下错误：
(index):1820 Uncaught ReferenceError: tinymce is not defined
at HTMLDocument.<anonymous> ((index):1820)
at HTMLDocument.dispatch (jquery.js:3)
at HTMLDocument.r.handle (jquery.js:3)

at Function.each (jquery.js:2)
at a.fn.init.each (jquery.js:2)
at a.fn.init.trigger (jquery.js:3)

但是当我直接从后端服务器加载页面时，没有错误并且图像显示正确！！
编辑：304 的清漆日志未修改

如控制台选项卡所示，问题出在HTML文档或Javascript(jquery(上，而不是图像本身。此外，为什么您的清漆日志不显示第二个请求？ 什么服务器返回"304 未修改"？ Chrome和Varnish之间有一些东西。 铬插件？
