Add-On Type(s)



Using ExpressionEngine’s CSS template provides a nice cache buster string of the most recent time the template was saved to the database. This is quite handy but still requires EE to process the template. This plugin will take a file path and use PHP to check the modification time returning a cache busting string like ExpressionEngine’s. This allows you to serve flat files from your server without having ExpressionEngine’s template parser run through the code first. It is very simple to use.


There are 2 parameters. One is required and the other is optional.

{exp:cache_buster file="/css/style.css"}

This will return


Where “1266264101” is the UNIX timestamp of the last time /css/style.css was saved to the server.

You can change the separator between the file and the timestamp with the use of separator=”” in the tag.

{exp:cache_buster file="/css/style.css" separator="?"}

This will return

I just stumbled upon this fantastic little add-on. With all my CSS being written in SASS and precompiled into a single compressed file, I don’t use EE’s css templates at all. That being the case, this provides exactly the cache-busting solution I need, with zero bloat. Fantastic!

Sometimes we don’t need all the bells and whistles that Minimee brings, because we’re already minifying and compressing our CSS and JS, so this simple plugin is all we need to make sure the latest versions of our JS/CSS files are retrieved.

Works as advertised and where other plugins haven’t. A staple on our site.

This plugin works great, I can highly recommend it.

It should also be noted that this will also work with your JavaScript files not just CSS files.
