JavaScript file caching issue in Internet Explorer

Internet Explorer caches the JavaScript file for purpose of fast rendering but sometimes it's problematic for the developers. When you do a new change in a JavaScript file, IE doesn't recognize that there has been a change straightaway unless you do a page refresh and it loads the old file which could cause the application to crash. 

So the solution is we need to force the browser to get the newer version of the JavaScript file but we also may don't won't to do this every time the page loads. 

You can append a version number at the end of the JavaScript file link as follows so that, IE recognizes that there has been a change and will reload the JavaScript file. 

<script language="javascript" type="text/javascript" src="Media/JavaScript/quoteandbilling.js?v=1.2"></script>
