New window shares browser cookie with parent?

[epaetz]

When you open a browser window from a new instance of IE, and then use
Control-N to create a new browser window, it appears that the new
browser window shares any browser-cookie with the parent window.

Can this relationship be documented anywhere?

I'm asking because our application sets a browser-cookie for the
session when a user logs into any of our three applications. The login
screen first clears any browser-cookie, then they login and get a new
browser cookie for their session while they are taken to their start
page within the app.

If they then use Control-N to open a second window and then navigate to
a different application login screen, the login screen clears the
browser cookie in the second window. (Let's say they want to work in
two of our applications at the same time, using two different browser
windows).

That action apparently clears the browser cookie in the parent window
too, leading us to believe that both the parent (original) and the
child browser windows share the same browser-cookie.

Again, is this behavior documented anywhere?

Yes, I know that the user could simple start up two distinctly separate
instances of IE. But I'm interested in the observed behavior so I can
understand why it does what we observed, which is not what we expected.

I posted similar behavior in the javascipt area on Wed, Jul 19 2006

Thanks,

Hi Epaetz,

Use Session variables instead of client cookies to track the logon status of
your users. You may also consider LDAP.
