PDF cache busting in your plugin

In our previous flat-file html site, I used this code to bust the cache and show any updated pdf file in a fast-moving workgroup type site that updates pdfs often. It works quite well.

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

// All pdf documents will have a cache busting
// string added to its url to guarantee freshness of updated documents

$(“a[href $=’.pdf’]”).click(function(){

var now = new Date().getTime();

$(this).attr(‘href’, $(this).attr(‘href’) + ‘?cache=’ + now );
});

});

However, because this pdf is embedded by javascript in the page dynamically and not viewed as a URL, this obviously doesn’t work. Is there an equivalent way to bust the cache with your plugin for frequently updated pdfs, using a hash or parameterized timestamp of some sort?
