title: What's the best way to handle caching on updates?
body: <p>I have a website, but every time I upload a new update or feature I'm afraid it won't show up to the user.</p>
  <p>It has happened a few times, we uploaded something new, but for some users, it didn't appear. The old information was left and it only appeared after a while.</p>
  <p>As I know that no users will clear their browser cache to prevent this, I would like to know if there is anything I can do on the development side to prevent this, and every time I upload something new, neither user will experience any problems or will not receive the news.</p>
  <p>I currently use AWS services like ec2, es3, bucket. cloud front and route 53</p>
