Question

I have a SQL Server 2008 table called “users” which stores users details. I have an aspx page that users will be redirected after they logged in. How might I find the list of users who are currently logged in without any updating this table? Do I need need a separate table to maintain login history? Please provide sample code.

Answer 1

i suggest you to use ASp.net Membership and roles functionality. Membership and Roles

1. you can store your credential in a session Variable and you can check it .
2. Use SqlState server to maintain session and login history SessionState Modes

3. You can store credentials in Cookies. which will sent to clients computer

    if(Session["islogged"] !=null && Session["islogged"] =="1")
   {
     //LoginSuccess
   }
   else
   {
     // loginFailed
   }
   

i prefer to use asp.net membership and roles provider to login functionaity, as it is easy and robust.
