title: chrome has cached html file that no longer exists on server
body: <p>There was a static site with no cache control: site.com/index.html</p>
  
  <p>now there is: site.com/index.php
  (index.html is deleted)</p>
  
  <p>On chrome (where the old website has been opened before)
  chrome shows cached version index.html</p>
  
  <p>Seems chrome loads the site without contacting the server</p>
  
  <p>.htaccess</p>
  
  <pre><code>   &lt;FilesMatch ".(css|html|swf)$"&gt;
         Header unset Cache-Control
     &lt;/FilesMatch&gt;
  </code></pre>
  
  <p>any other .htaccess variations on cache busting do not work because chrome doesn`t seem to contact the server</p>
