title: How to find the list of available users using asp.net and SQL Server?
body: <p>I have a SQL Server 2008 table called <code>users</code> which stores users details. I have an aspx page that users will be redirected after they logged in.</p>
  
  <p>How might I find the list of user with their user details who are currently logged in without any updating this table? Do I need need a separate table to maintain login history? </p>
  
  <p>Some one suggest me to use ASp.net Membership and roles functionality. By using this how could I able to find the list of logged in users? i.e, online users and offline users?</p>
