title: Grails Web App - Show current logged in users
body: <p>ive created a grails app and used Apache Shire plugin <a href="http://shiro.apache.org/" rel="nofollow">http://shiro.apache.org/</a> for security and logging in purposes.</p>
  
  <p>I wanted to find out if anyone knows how I can get a list of the users who are currently logged in to the web application? </p>
  
  <p>Where would this information be stored / on the servers side in a cookie or a session?</p>
  
  <p>Basically i want a widget showing all the current users whom are logged in to my web application currently.</p>
