title: How to force clear user's browser all the time?
body: <p>We're working on a website. Our client want to check the website daily, but they're facing a problem. Whenever we make a change on the website, they have to clear their browser cache.</p>
  
  <p>So I added the following header to my server configuration</p>
  
  <pre><code>Cache-Control: no-cache
  </code></pre>
  
  <p>As far as I see, firefox is receiving this header and I'm pretty sure that it is obeying it.</p>
  
  <p>My question is, is this "Cache-Control: no-cache" guaranteed and does it work across all the browsers (including IEs)?</p>
