title: Handling regularly updated files on Amazon S3 and CloudFront
body: <p>If I am regularly overwriting files on S3, CloudFront caches them when I serve them in the browser. I was looking into Invalidation but there's a limit on how many validations at once it seems which wont work for a multi-teant website.</p>
  
  <p>The only solution I can see is when overwriting a file, delete the old file and change the name of the new file (I was just going to add the TIMESTAMP to the end) so that CloudFront doesn't pull the cached version.</p>
  
  <p>Would this be the most advised way to handle this sort of thing?</p>
