title: What broswers don't support Cache Busting?
body: <p>I've been working on an eCommerce site that recently did a big code release. We have been modifying/optimizing some of the .js and .css for a few months. Every time a user comes to the site they have to clear their cache.</p>
  
  <p>We have started adding a query string to the urls
  /Resources/Javascript/GuidedNavigation.js?v=1</p>
  
  <p>However, from what I'm hearing not all browsers support this. I haven't been able to find an explanation as to what browsers support query strings. Presumably all modern browsers but we still have a decent amount of traffic coming in through IE7-IE9.</p>
