title: wicket sessions: how to prevent "jsessionid" from showing up in googlebot crawl results?
body: <p>When google crawls our site the resulting URLs all have the <code>jsessionid</code> appended to them. 
  Is this happening because the app server is detecting a lack of cookie support in Googlebot, forcing the session to be maintained via URL-rewriting? Is there anything I can do about it? </p>
  
  <p>Is the solution simply to never call <code>Component.getSession()</code> ? Is there anything like <code>HttpServletRequest.getSession(false)</code> ?  </p>
  
  <p><strong>Edit:</strong> just found <code>org.apache.wicket.Session.exists()</code></p>
