title: How do I force the refresh of javascript files in a browser?
body: <p>I've been using quite a bit of JQuery, KnockoutJS and other JavaScript stuff for a web app I am building. Most of the JS is off in its own nice separate files. The issue I have is that the browsers cache those files so when I push a change people have to refresh a few times before they get the updated file. Recently I made a significant change to how some data was passed and the cached versions of the files caused some errors and worse, some data to get erased.</p>
  
  <p>How do people handle this? Is there a way to force refresh of files?</p>
