Logg off users with session.timeout

[Guest]

I wonder if it is possible from a button click or a link to logg off (some
unwanted logged on users or all users) in an asp.net application with
session.timeout or another way?Thankfull for any code example.

 

[Michelle]

Here's what we do; if the session has expired or doesn't exist we
redirect to a "timed out" page. The timeout page contains only a
couple lines of javascript to pop up a box alerting the user that they
have timed out then redirects them back to the login page. We check
the session on every page to make sure it still exists.

in each page:
--------------------
If Session("User") Is Nothing Then
Response.Redirect("../TimedOut.aspx")
End If


timeout page:
--------------------
function window_onload()
{
alert('Your session has timed out. Please log back on.');
top.location.href = 'default.aspx';
}


I'd also like to hear what other people are using to see if we could
change our method to something better - or if this is the norm.

Thanks!
Michelle

Thanks Michelle for your answer but what I need is logging off certain users
when their sessions have not ended yet. Imagine that I'm an administrator and
want to expell some unwanted users from the applikation from a button click.
Is there any way maybe to use formsauthentication.signout() method? The
problem is how to identify first these users?

But how to use formsauthentication.signout() method to logg off all logged on
users at the same time from the application? Do I need to make any change in
web.config too?

Put a button on a form, map its click event to a function that calls the
signout method. each user who chooses to log out follows the process.

I don't know if you understood what I meant. What I need is from a button
click be able to logg off all users at the same time from the system (it is
me who will do that and not them one at a time)?

viktor9990,
I guess u can only control how long they can stay on the site and what
they can do.But logging them all out at the same time?????

You have to use a bit of sideways thinking
to get around that type of logic.

If you think that logging everyone off is the problem,
you will not be able to do it from within code.

OTOH, if you know that all it takes to log everybody off
is to restart the application, there's a simple solution :

Write a little app to "touch" ( save ) global.asax.

That will restart the application
and everybody will be logged off.

I like your idea. I put the code in a header user control rather than
typing the code into every page and it works like a dream.
