title: Force content update to cloudfront, without using invalidate
body: <p>I am using cloud front as CDN. Is there a way to force a content update? I have a file on my origin server which I've updated with a new version (same name, new date time stamp). But when I check it in cloudfront, its still the old file.</p>
  
  <p>I have seen <a href="https://stackoverflow.com/questions/1268158/force-cloudfront-distribution-file-update">this thread</a> which suggest one way as invalidate, but I don't want to do that because its an overhead I think and there can be maximum 3 invalidation request running at a time. I read that cloudfront is supporting <a href="http://aws.typepad.com/aws/2012/05/amazon-cloudfront-support-for-dynamic-content.html" rel="nofollow noreferrer">dynamic content using query parameters</a>, can I make use of it somehow to force cloudfront to pull the latest content from the distribution server.</p>
