cdn - Windows Azure CDN 中的更新文件

Question

我有 blob 存储和 CDN 端点，用于存储我的静态内容。
现在我想更新 app.js 文件，因为它被修改了，但是当我将此文件写入 blob 时，CDN 仍然给我旧的 app.js 文件。如何更新我的 app.js 文件？或者我必须等到我的缓存不会结束？

只是你不能在它到期之前更新缓存对象。

来自 https://msdn.microsoft.com/en-us/library/azure/gg680303.aspx :

If you no longer wish to cache an object in the Azure Content Delivery Network (CDN), you can take one of the following steps:

• For a Azure blob, you can delete the blob from the public container.

• You can make the container private instead of public. See Restrict Access to Containers and Blobs for more information.

• You can disable or delete the CDN endpoint using the Azure Management Portal.

• You can modify your hosted service to no longer respond to requests for the object.

An object already cached in the CDN will remain cached until the time-to-live period for the object expires. When the time-to-live period expires, the CDN will check to see whether the CDN endpoint is still valid and the object still anonymously accessible. If it is not, then the object will no longer be cached.

No explicit "purge" tool is currently available for the Azure CDN.

如果可能，其他解决方法包括使用假查询字符串或新文件名。看这里: https://stackoverflow.com/a/8773202/908336
