我有一个带有各种 Telerik RadControls 的 aspx 网页，每次加载此页面时，Safari 移动似乎都会再次下载所有资源文件 - 例如，在每个页面请求时将以下文件下载到 ipad - 似乎什么都没有缓存，就像在其他非移动浏览器上一样。
http://aspnet-scripts.telerikstatic.com/ajaxz/2010.3.1109/Common/Navigation/NavigationScripts.js
http://aspnet-scripts.telerikstatic.com/ajaxz/2010.3.1109/PanelBar/RadPanelBarScripts.js
http://aspnet-scripts.telerikstatic.com/ajaxz/2010.3.1109/Input/TextBox/RadInputScript.js
http://aspnet-scripts.telerikstatic.com/ajaxz/2010.3.1109/ListBox/RadListBoxScripts.js
http://aspnet-scripts.telerikstatic.com/ajaxz/2010.3.1109/ComboBox/RadComboBoxScripts.js
http://aspnet-scripts.telerikstatic.com/ajaxz/2010.3.1109/Grid/RadGridScripts.js
即使 CDN 资源设置为缓存并具有 ETAGS，每次传递的 JavaScript 也超过 100K。
每次笔记本电脑浏览器缓存上面的资源文件而 ipad 没有缓存时，我已经为 ipad 和运行 IE/FF/Safari 的笔记本电脑安装了提琴手。
我认为这就是为什么我的应用程序在 Ipad 上的执行速度明显较慢的原因，尽管它可能也是 Ipad 上的缓慢 javascipt 解析......
有没有其他人有这个问题？我在这里遗漏了一些明显的东西吗？
谢谢。

我通过使笔记本电脑成为 iPad 的 http 代理来监控笔记本电脑上的 iPad 流量。
提琴手的额外信息：
Fiddler v2.3.0.0，笔记本电脑结果来自 IE8，iPad 版本。3.2.2.
从我的笔记本电脑，如果我去http://demos.telerik.com/aspnet-ajax/listbox/examples/default/defaultcs.aspx
并在提琴手中单击“First Look”几次后：

我今天再次尝试了与上述完全相同的测试，并注意到：
1) iPad现在正在缓存 javascript
2) Telerik 演示没有使用 CDN，但它们是昨天的！（见下面的结果与上面的结果相比）
