title: How to reload a Java InputStream
body: <p>I am parsing a webpage using a BufferedReader wrapped around an InputStream in Java:</p>
  
  <pre><code>HttpURLConnection conn = (HttpURLConnection)url.openConnection(myUrl);
  InputStream stream = conn.getInputStream();
  </code></pre>
  
  <p>The problem is that the numbers I want to get from the page are dynamically generated with Ajax calls, and aren't available in the stream.  Is there some way I can refresh the stream after waiting a bit, or can anyone think of some other way to get the data?  The page is <a href="http://www.otcmarkets.com/otcqx/marketActivity/closing-otc-summary" rel="nofollow">here</a>.  The numbers I need are the "Dollar Volume" and "Share Volume" in the middle of the page.</p>
  
  <p>Thanks,
  Jared</p>
