pdf documents will have a cache busting

pdfcachebust.js

<script type="text/javascript">

	jQuery(document).ready(function($){

	   // All pdf documents will have a cache busting
	   // string added to its url
		$("a[href $='.pdf']").click(function(){
				
			var now = new Date().getTime();
			
			$(this).attr('href', $(this).attr('href') + '?cache=' + now );
			
		});
	
	});	
	
</script>

I had a need to cache a pdf file and came up with this idea.

It takes the link to the pdf file and adds a random number to the query that will stop the browser from caching the file, in this case a pdf.

It can easily be modified for any link type
