Ho do I redirect users to a particular web page on logout?

When the user clicks on the Logout link, he/she is presented with the page at C:\Program Files\DeskNow\desknow\jsp\original\Exit.jsp (or /var/desknow/desknow/jsp/original/Exit.jsp) . You can alter that page to send a redirect to any URL.

For example, to redirect the user to www.yahoo.com, edit the Exit.jsp file and change it to this:

<html>
<meta http-equiv="refresh" content="0; URL=http://www.yahoo.com">
</html>
