title: Element SESSIONID is undefined in SESSION - CF9
body: <p>please help. We have a CFM system that works 100% for most of the users except a few (less than 10 out of 3000+ users). All users can login without a problem and session variables be set. The login page then send them to the dashboard. We then use the <code>SessionID</code>, among other factors, to encrypt the URL string.</p>
  
  <p>However for the 10- users, when they reach the dashboard, we get the error</p>
  
  <pre><code>Element SESSIONID is undefined in SESSION
  </code></pre>
  
  <p>The only resolution we have to far is for them to close the browser entirely then start from scratch. Everyone else is working fine.</p>
  
  <p>Sure enough, the session struct dump has no <code>SessionID</code>. I know that the <code>sessionid</code> is basically <code>AppName</code> + <code>CFID</code> + <code>CFToken</code>. How can I recreate the SessionID without sending them back to the login or losing the already set session variables?</p>
