title: Can unique query string in the URL prevent website being cached in the browser?
body: <p>There are many occasions where my client sees a cached version of the website from the link I shared to them. After a while it can become very frustrating to make sure they're not seeing a cached version of the website. Are there ways out there to avoid this? </p>
  
  <p>I often times have to ask them to clear their browser cache and point them to online how tos in how to clear their respective browser's cache.</p>
  
  <p>I am testing a hack where I use query string to produce a unique URL. It's not being processed in the server, the query string is simply there to have a unique url every time I share it. It's currently working in my browser and to people I've shared but I'm not sure if it's a bulletproof solution.</p>
  
  <p>For example: </p>
  
  <p><a href="http://examplesite.com/index.php?v=25" rel="nofollow noreferrer">http://examplesite.com/index.php?v=25</a></p>
  
  <p><a href="http://examplesite.com/index.php?d=09282017" rel="nofollow noreferrer">http://examplesite.com/index.php?d=09282017</a></p>
