Force server to load latest CSS file

 / Published in: CSS


This is sometimes not the best solution to a server caching your css files. But if you want to force a stubborn server to serve the most recent css file to the browser this seems to work. Could slow things down a touch, but for small css files not really noticeable.

Just change the var css to match the path to your css file, and then offer a non jscript version pointing to the same file.

Essentially by adding the query to the end of the css file the server thinks it needs to load it. I used date and getTime to create a number combo and tagged it to the end.

Use: put the following code into your right where your normal tag would go to point to your css file.

  1. <script type="text/javascript">
  2. // create a number with Date and getTime
  3. var x = new Date().getTime();
  5. // create a variable with the path to your css file?=
  6. var css="css/styles.css?="+x;
  8. // write the link tag with new css var
  9. document.writeln('<link rel="stylesheet" type="text/css" href="'+css+'">');
  10. </script>
  11. <noscript><link rel="stylesheet" type="text/css" media="all" href="css/styles.css" /></noscript>
