I have come across this piece of code for embedding custom css in my custom BE module extension.
<f:asset.css identifier="myextcss" href="EXT:myExt/Resources/Public/Css/myext.css" />While it works well, the browser caches this file. How can I prevent it from being cached? I am aware that pages can be set as non-cachable in FE, but in BE I only want to prevent this specific file from caching, not the entire module.
After experimenting for a bit, I discovered a clever solution.
I inserted the following lines into my controller:
$myKey = substr (str_shuffle($_GET['key']),0,8);
$this->view->assign('myKey', $myKey);
Then, in my fluid template, I added this code:
<f:asset.css identifier="customCss" href="EXT:customExt/Resources/Public/Css/custom.css?{myKey}" />
This way, the browser always detects a "new" file request and refreshes it.
