Link a CSS file with version number for cache busting

问题

css-file is named: style.css?v=1

the link inside of html: <link rel="stylesheet" href="style.css?v=1">

---

Contrary to the classic style.css the style.css?v=1 doesn't get recognised:

Failed to load resource: the server responded with a status of 404 (Not Found)

Did I miss something? What's important to versioning files and where does the syntax ?v=1 come from?

回答1:

• The expression style.css?v=1 for the browser means a dynamic file like "fetch me the file style.css with a parameter named "v" set to 1". As long as you change the value of the v parameter, the file will be fetched as a new unique url.
• The expression style.css?=v1 has no meaning.
• The expression style.css?1 could also work.
