title: Flex save file dialog for URL
body: <p>I will have a list of links to PDF documents in my Flex web app.</p>
  
  <p>What I want to do is that upon clicking some button, open SAVE AS dialog for some pdf from the URL list and download it to disk.</p>
  
  <p>What I want to avoid is viewing PDF in browser.</p>
  
  <p>ALL I know is that <code>flash.net.FileReference</code> will take raw data but no links. So is it possible ?</p>
