IIS7 的 AppCache mime 类型
我们正在托管一些 HTML5 游戏，它们利用 offline.appcache 功能让游戏缓存得更好。
然而，为了提供 .appcache 类型，我必须将 mime 类型添加到服务器 (IIS7)，这样它就不会出现 404。当我这样做时，它拒绝提供任何图像或 CSS 文件！当我请求 CSS 或图像文件时发送到浏览器的错误是：
The page cannot be displayed because an internal server error has occurred.
我添加的扩展名是 appcache，MIME 类型为 text/cache-manifest。
知道为什么会导致这种行为吗？
We're hosting a couple of HTML5 games that utilise the offline.appcache feature letting games cache a lot better.
To serve the .appcache type however, I had to add the mime type to the server (IIS7) so it wouldn't 404. When I do, it refuses to serve any images or CSS files! The error sent to the browser when I request a CSS or image file is:
The page cannot be displayed because an internal server error has occurred.
The extension I am adding is appcache with the MIME type text/cache-manifest.
Any ideas why it's causing this behaviour?

终于弄清楚了，我在服务器级别而不是站点级别添加了 mime 类型。其中一个站点已经定义了该 mime 类型。这引起了冲突。但奇怪的是，具有双重定义的网站很好，其他网站却失败了。
Finally figured it out, I added the mime type on server level not site level. One of the sites already had that mime type defined. Which caused a conflict. But bizarrely the site with the dual definition was fine, it was the other sites that failed.
添加 .appcache 时我遇到了类似的问题。所有 .js 和 .css 文件请求都会从 IIS 响应错误。我意识到这是因为我没有指定 NETWORK: 部分。
我的工作 .appcache 现在强制刷新所有文件并且不会导致错误：
I ran into a similar issue when adding the .appcache. All .js and .css file requests responded with an error from IIS. I realized it was because I had not specified a NETWORK: section.
My working .appcache now forces all files to be refreshed and doesn't cause errors:
