我正在浏览我最喜欢的网站的HTML … … …我在标记中看到了这一点：
<link href="/Content/all.min.css?d=20090107" rel="stylesheet" type="text/css" />
什么是“？d = 20090107”？我假设它是某种日期，但我不知道为什么它在文件的路径。有任何想法吗？

这就是为文件名添加一些唯一性，所以当他们更改CSS文件时，他们可以更改额外的位，以完全确保每个客户端将重新加载CSS，而不是使用缓存版本。
Web服务器将忽略该参数并正常提供/Content/all.min.css
注意：尽管CSS可能是动态生成的，但这是确保重新加载的常见习语，并且给定参数是日期，似乎很可能。

We’ve been using the Expires or
Cache-Control Header since we
launched. This saves the browser
round-trips when getting infrequently
changing items,such as images,
javascript,or css. The downside is
that,when you do actually change
these files,you have to remember to
change the filenames. A part of our build process now “tags” these files with a version number so we no longer have to remember to do this manually.
