将脚本版本放在哪里有什么不同吗？查询参数或路径。利弊？
最佳答案
是的，有区别!
您需要将其作为文件名的一部分，否则某些浏览器不会缓存它。

According the letter of the HTTP caching specification, user agents should never cache URLs with query strings. While Internet Explorer and Firefox ignore this, Opera and Safari don’t – to make sure all user agents can cache your resources, we need to keep query strings out of their URLs

Jacob Hoffman-Andrews, mentioned that Squid, a popular proxy, doesn’t cache resources with a querystring. This hurts performance when multiple users behind a proxy cache request the same file – rather than using the cached version everybody would have to send a request to the origin server.
(注意 Squid 中的默认行为有 since changed )
最后，有一个很棒的小服务可以让您“ping”Internet 上的一个页面并验证文件(及其使用的资源)的“可缓存性”
Cacheability - 检查 www.stackoverflow.com's Cacheability
您会注意到 StackOverflow 提供的 CSS 和 JS 文件在查询字符串中进行了版本控制，因此服务报告:
This object will be fresh for 1 week. It can be validated with Last-Modified. Because it contains a query ('?') in the URL, many caches will not keep this object.
