title: How to get the parameter values from HTTP "Referer" header?
body: <p>I got the url value using <code>request.getHeader("Referer")</code> e.g.:</p>
  
  <pre><code>string rr=request.getHeader("Referer");
  &lt;%= rr %&gt;
  </code></pre>
  
  <p>I got the url as <code>http://www.sun.com/questions?uid=21&amp;value=gg</code></p>
  
  <p>Now I stored that url in as string, how do I get the value parameter value as <code>uid=21</code> and <code>value=gg</code></p>
