title: Force browser to not use cache when requested for file using anchor tag
body: <p>I have an anchor tag that is used to request the download of a file.</p>
  
  <p>Like this:</p>
  
  <pre><code>&lt;a href="app/results?fileName=t12.txt&amp;other-param=something" title="Click to download"&gt; Download &lt;/a&gt;
  </code></pre>
  
  <p>The file may be modified on the server very often, so I want to make sure the browser does not cache the file.</p>
  
  <p>However, testers found out that, although it seems to always download the file when you click on the link, when you right-click on the link and choose "Save As...", the browser seems to choose to use the cached file instead. This was tested with IE9.</p>
  
  <p>How can I force the browser (especially IE9) to always download the file in every case?</p>
