Instant CDN on Google App Engine

[lin]

在GAE上发现这个：
http://cdn-cloud.appspot.com/

虽然对CDN不了解，
但是对它开三级域名这个功能很感兴趣。
谁知道我提疑问：

对FotoRatan很有用。可是我不懂的东西太多。

貌似是个新功能？so cool.

You can use wildcards to map subdomains at any level, starting at third-level subdomains. For example, if your domain is example.com and you enter text in the web address field:

Entering * maps all subdomains of example.com to your app.

Entering *.private maps all subdomains of private.example.com to your app.

Entering *.nichol.sharks.nhl maps all subdomains of nichol.sharks.nhl.example.com to your app.

Entering *.excogitate.system maps all subdomains of excogitate.system.example.com to your app.

If you use Google Apps with other subdomains on your domain, such as sites and mail, those mappings have higher priority and are matched first, before any wildcard mapping takes place. In addition, if you have other App Engine apps mapped to other subdomains, those mappings also have higher priority than any wildcard mapping.

Note that some DNS providers might not work with wildcard subdomain mapping. In particular, a DNS provider must permit wildcards in CNAME host entries.
