问题描述
我开始关注HTML5s允许离线Web应用程序的能力。
I'm beginning to look at HTML5s ability to allow for offline Web applications.
前段时间我发现使用CDN对我的应用程序运行良好，所以我一直坚持使用它们，主要是为了jQuery。
A while back I found that using a CDN worked well for my applications, so I've been sticking with them, mostly just for jQuery.
但是，似乎清单文件不允许缓存跨域资源。
However, it doesn't appear that manifest files allows cross-domain resources to be cached.
此时我一直在使用相关。我的jQuery类似于中定义的内容。
At this point I've been using the catch-all manifest as described by the relevant Dive Into HTML5 tutorial. My jQuery is pulled in similar to what's defined in the HTML5 Boilerplate.
我' d喜欢能够继续从CDN为在线用户提供jQuery服务，但可能有一个本地副本缓存用于离线访问。
I'd like to be able to continue to serve jQuery from a CDN for online users, but perhaps have a local copy cached for offline access.
是否值得尝试追求这一点路由，或者我应该切换到只为我的网站提供jQuery服务所有请求？
Is it worth trying to pursue this route, or should I just switch over to just serving jQuery from my site, for all requests?
谢谢。
推荐答案
实际上，您可以编写包含jQuery CDN链接的清单。就像我的 app.manifest ：
Actually, you can write your manifest that has a link to your jQuery CDN. Just like my app.manifest:
CACHE MANIFEST
# 2012-01-20:v4
http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
这是HTML细分：
<html manifest="app.manifest">
<head>
....
</head>
<body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
....
</body>
</html>
对我有用。
