我使用清漆来加快客户的网站加载时间。我的页面上的图像有问题。页面上的图像未显示在页面上。这是我按Ctrl + f5时的chrome输出标题：

问题是图像未显示在页面上，但它显示在chrome开发人员面板的预览部分中。此外，如果我在浏览器的新选项卡中打开图像，它会正确显示。 清漆版本是4.0.4。并且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）上收到以下错误：
(index):1820 Uncaught ReferenceError: tinymce is not defined
at HTMLDocument.<anonymous> ((index):1820)
at HTMLDocument.dispatch (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，图像显示正确!!

答案 0 :(得分：0)
正如您的控制台选项卡所示，问题在于HTML文档或Javascript（jquery），而不是图像本身。 而且，为什么你的varnishlog没有显示第二个请求？什么服务器返回＆＃34; 304未修改＆＃34;？ Chrome和Varnish之间有一些东西。 Chrome插件？
