Hi all,

In my project there is a requirement. If a user logged in at a time
since he/she logged out others are not allowed to loggin using the
same user name. That is to avoid multiple logins using a account. How
to do this?

I had got a idea and implemented.

1. When a user logs in storing the username, ip, login time to db.
2. When a User logs in i'll check the table whether the username
exists in the table or not if yes i'll not allow the user to login
else i'll allow to loggin.
3. When he logs out i'll delete the record from the table. Then he/
she can login again.

But there is a problem in this the user can close the browser directly
or right click in the taskbar and close it or by pressing Alt + F4. So
for this i have to catch the things in Javascript and trigger the
logout.

Is is possible to catch the events in Javascript, if yes please
provide me.

Or Is there any other method to restrict multiple login using single
account.

Thanx in advance.

There's no way to tell if the user closed his browser. Or turned off
his computer, unplugged from his network or any of a number of things.

You can use a short timeout, i.e. 15 minutes, and if they don't do
something in that time period their session gets deleted.

But one of the ones I like best is if one person logs on while another
one is using that account, the first one is logged out automatically.
It gets to be very annoying - and they soon stop sharing their account
info with others.

Jerry has the right idea.

Having the user session time out is fine - but can be counter
productive.
Having the user logged out if someone else logs in is a good way to go
since it alerts the user someone else has access to their account.

Blizzard does that :)

When a user logs in or clicks an option in their account, store the
current time in a database, if someone tries to log on to the same
account, check to see if the last action they made was in the last 15
minutes. If it is, deny access. When the user clicks on logout, reset
the time in the database.

this way, if someone does close their browser then all they have to do
is wait 15 minutes, and whilst the user is actively using their
account, no-one else will be able to log in.

Jerry has the right idea.

I hope these people are not being paid by the hour :-)

If some "project" did this to me I'd complain right up to the managing
director to get it "fixed".

dialog to user that is u wantto continue like that......if no response
than change the status in db to notactive and give a chance to other..

There's the DOM event document.onunload.
Maybe you could use it to send an ajax request that terminates the
session.
But it don't really know how reliable this would be.

Good luck

Only effective if the user closes the page && has Javascript enabled. Net
outage, app or pc crash, cable disconnect, etc etc. won't be handled
correctly. Just face the fact web apps have stateless user connections.

I haven't seen a failsafe mechanism yet. Nowhere. (Except those
using one-time key devices or keyculators) Simplest is (as suggested by
others) when (a) user logs in using a given set of credentials,
immediately close any open session matching them and inform about a new
login from another address and offer the option to have their password
reset and sent by mail. If they choose that option, block the other opened
session as well.

In case their creds were obtained without their approval, they ought
to be pleased to find out their account details were nicked and should be
changed immediately.
