title: umbraco, get param from url or set session
body: <p>I have in umbraco</p>
  
  <ul>
  <li>a content tree with pages to be displayed in navigation and frontend</li>
  <li>a storage folder with different kinds of records</li>
  </ul>
  
  <p>I would like to have a single page in Umbraco in the content tree, that can display info from just one record stored in the storage folder.</p>
  
  <p>Example:
  Storage folder contain several doc-types of animal</p>
  
  <p>In content tree I can do different kinds of listing by category (four legs, predator, cutly etc.). When clicking any animal from any list I would like to go to the same page plus a parameter:
  <a href="http://mysite/animal.aspx?showthis=1254" rel="nofollow">http://mysite/animal.aspx?showthis=1254</a> (that's the lion)</p>
  
  <p>Can that be done? I cannot find anything about hos Umbraco/XSLT can read a parameter from the url.</p>
  
  <p>If not possible can it be done with setting a session in xslt?</p>
