问题描述
我们在Web服务器上有一个图像文件夹，可以通过CDN发布。有时，我们会在URL后面附加类似查询字符串的语法，以帮助我们刷新已更改的内容，即使这种情况很少发生。例如：
We have an images folder on our web servers that we may publish via a CDN. Sometimes we append query-string like syntax to URL's to help us freshen content that has changed, even though it rarely does. Example:
/images/file.png?20090821
URL是否可以在您的平均内容传送网络中使用？
will URL's like this work with your average content-delivery-network?
推荐答案
Yes, We use Akamai, which keeps a cached copy of each distict url requested including the querystring. So the first request for /images/file.png?20090821 will go to the origin server. Requests there after for /images/file.png?20090821 will get the image from the Akamai servers. The next day, assuming the img src changes to /images/file.png?20090822, the first request will go to the origin server again.
