title: Stale javascript cache files and MVC4
body: <p>Does MVC 4 bundle, resolve the issue with stale .js files? These .js files are cached on client's computer as such they are sometimes not updated with new deployment.</p>
  
  <p>Will bundling and letting the framework figure out if the etag matches solve the issue in MVC 4?</p>
  
  <p>Similarly what are the alternatives when using MVC 3?</p>
