detecting idle session or closed window
Hi Experts,
I would like to know how to determine when a session is idle for a period of time (so I can kill their idle connection) or a user has closed the browser (without logging out first). My website is using asp with vbscript and has a SQl server backend that keeps track of the current log in sessions.
Thanks!!!

Hi,
you can detect/set this in your script:-
<html>
<body>
<%
response.write("<p>")
response.write("Default Timeout is: " & Session.Timeout & " minutes.")
response.write("</p>")
Session.Timeout=30
response.write("<p>")
response.write("Timeout is now: " & Session.Timeout & " minutes.")
response.write("</p>")
%>
</body>
</html>

response.write("<p>")
response.write("Timeout is now: " & Session.Timeout & " minutes.")

Hm ... but on some websites, when I close the window, a smaller window pops up. Does this show that it's possible to determine when a window gets closed?
For example, if you go to www.time.com and you close the window, a smaller window pops up and asks you to subscribe.
How do they determine when they've closed the larger window? Thanks.

They put a javascript function in the onUnload event. <body onUnload=DoSomeFunction();
This isn't bad, but don't think it's foolproof either. It only works if javascript is turned on. It only works if you try to close the window (i.e.: does *not* work if you press back button the leave the site), etc.

HTTP is what is called a stateless session i.e. browser requests a page, server serves that page to the browser (client), and then forgets about them... i.e. the browser will be identifiable via session info at the server (when the browser makes its next call within the timeout period)... but the server can't contact the browser independantly... unless you use a form of web service that is.
Javascript is what most use to detect the window closing as wunyu says... but i don't like that method... i rather log users at a db at the server, thier logon time etc.
P.S. Hope this helps.

OR
just set a variable in the users session that stores the time they logged on and update it using a timer in your pages, and once its timed out or about o you will know - with a bit of jiggery powkery u could do allsorts.
P.S. Don't think there is a simple command for knowing how long a session has left, and there is no way of detecting when a user closes thier browser without using javascript...
alternatively you could have some code sitting in the application object that poles the logged on users and does things accordingly.

>> IIS handles this based on your server's configuration - I believe 20 minutes is the default value.
Where do I find this information or where do I configure this?
Also, in yahoo mail, for example, if a user logs into their email account and then copies down that URL, if they close the browser and open another browser and goes to that same URL, yahoo asks for a password. How did yahoo know that the user had closed the browser or how do they know when to expire a session is more appropriate.
Thanks.
