关于如何更改静态资产的文件名以防止过时的浏览器缓存版本的资产文件的想法

Question

I have a website that I host with PHPFog. PHPFog, for those who don't know, makes it very easy to deploy an app to multiple application servers with a simple git-push. I would love it if there was some way to automatically update the version number of my javascript/css files with every git-commit or git-push. Or somehow maybe just append the 'build' unix timestamp to the filename. The goal of course to queue browsers to reload the asset file instead of going with the cached version. Does anyone know of a good way to do this?

Answer 1

You can append a bogus query string to your CSS files - such as

styles.css?<?php print $release; ?>

The release identifier can be anything you want - perhaps a timestamp, git hashref, or tag.
