  Detecting how many concurrent times a user has logged in

  Feb 13, 2013 04:58 PM|LINK

  Is it possible to know how many concurrent times a user has logged in? We are developing a web application in which we want to limit the number of concurrent times a user is able to login.

  Regards.

  Hello,

  You can do something like this. Call the below code when the user log in

  int maxLimit = 5;
  
              if (Membership.GetUser("Username here").IsOnline)
              {
                  if (Application["Username here"] == null)
                      Application["Username here"] = 0;
                  else
                  {
                      int times = int.Parse(Application["Username here"].ToString());
                      Application["Username here"] = times++;
                  }
              }
  
              if (int.Parse(Application["Username here"].ToString()) == maxLimit)
              {
                  //cancel the login
              }

  And when the user logs out, decrease the Application variable value by 1.

  sounds like an ntier application. abstract it out into a small database/table/csv/txt and post your data.
