Active User count in ASP .Net/C# application

[tim007]

Hi,

How can we get tthe number of active users connected to our web application.


I have added application varible that gets incrimeted at session_start and then is decreased at session_end


void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started

Application.Lock();
Application["TotalUsers"] = Convert.ToInt32( Application["TotalUsers"].ToString()) + 1;
Application.UnLock();


}

void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends.
// Note: The Session_End event is raised only when the sessionstate mode
// is set to InProc in the Web.config file. If session mode is set to StateServer
// or SQLServer, the event is not raised.

Application.Lock();
Application["TotalUsers"] = Convert.ToInt32(Application["TotalUsers"].ToString()) - 1;
Application.UnLock();

}

but the count keeps on increasing ...

i get the total users but not the total ACTIVE USERS


thanks

Hi,

This problem is coming may be because your session_end procedure is not getting called. So if you want to execute the code in session_end procedure then you have to call Session.Abandon() method when user Logs out from the web application.

Also, please note that the Session_End is only called if you are using InProc Session....

But this is not fired if the user just closes the browser ... session_end is not called when the user just closes the browser.

if 5 users are connected and two of them just close the browsers

the Count would still be 5 where as it should have been 3...

we wont get the correct count of connected users

But this is not fired if the user just closes the browser ... session_end is not called when the user just closes the browser.

Then you will have to detect when the browser is closing.
There have been a number of threads here discussing how to do that.
