You can't control the headers sent from a server that you don't control.
您无法控制从您无法控制的服务器发送的标头。
In other words, either host a copy yourself or there's nothing you can do about it.
换句话说，要么自己托管副本，要么对此无能为力。

You can grab the code from the resources and serve them from your site directly, in these way you can manage the cache, but if some update occurs from the sites related to the resources, you miss it, or you have to control everytime ..chose at your convenience.
您可以从资源中获取代码并直接从您的站点为它们提供服务，通过这种方式您可以管理缓存，但是如果与资源相关的站点发生了某些更新，您就会错过它，或者您每次都必须控制..在您方便的时候选择。

You can try copy their scripts and host them youself. Just write a script and add it to cron to load new versions automaticly. Working on it now myself.
您可以尝试复制他们的脚本并自己托管。只需编写一个脚本并将其添加到 cron 即可自动加载新版本。现在我自己在努力。
