Hi,

I'm looking for sample code or your input, on how to create a new window
with a new session, while the parent window remains in its original session.

For example, a link from the parent window would open a new window in a new
session, but the parent session would still be valid.

Is this possible?

Thanks for any tips.

Frank

That's not possible. For the web browsers, the session is linked to the
process in which the web browser runs. If you start two instances of the
IE process (IEXPLORE.EXE), each one will have a distinct session ID.
However, if you just open a new window from the current instance of
IEXPLORE, the new window will run in the same process, thus have the
same Session ID. It is not possible using a link to start a new instance
of a process on the client, or to open a new window in another existing
instance of a process.

What you can do, however, is use another way to identify your windows
(for example using a combination of SessionID and window name, since the
window's name must be unique inside of a session), and to implement your
own "window-session" management on the server. it's not very difficult.

Also (you didn't precise what kind of client you have), if you have a
rich client (for example WinForms application), then you can start
multiple sessions from one client only using different CookieContainers
for each web request. I don't think it's what you're doing though.

Laurent

This simply is not true - at least, not with IE7...

I just tried it... opened a debug page on my website which shows the
SessionID, then clicked Ctrl-N nine times - each of the 10 browser instances
has a different SessionID...

I suspect a server-side issue. What happens when you refresh one window,
is the SessionID the same, or is it different? Also, what happens with
Firefox?

I noticed that the session management changed quite a lot in ASP.NET 2.0
compared to 1.1. I just made a few quick tests here and I am having
troubles getting a consistent SessionID. I can't test more tonight
unfortunately.

Normally, IE7 behaves the same as IE6, and the SessionID is attached to
the process.

Greetings,
Laurent

OK, I got it. To have the SessionID set consistently on the server side,
you need to actually use the Session object. If you just observe the
SessionID, but you don't actually use the Session object for storage,
then the SessionID will be different on every request. I have to admit,
I was not aware of this. IIRC, it was different in 1.1 (but I might be
wrong).

Anyway, if you use the Session object for storage, and then observe the
session ID, it will be consistent when refreshing the page, and it will
also be the same if you open a new window using Ctrl-N.

HTH,
Laurent

In Firefix you can only have one instance of the browser application, so
you can't open separate sessions.

I would rather suspect a change in IIS than a change in the framework.

Interesting...

So it would seem...!

I wonder just how absolutely consistent this is across client OS / browser
and version of IIS on the webserver...?

Utter nonsense!

Click the FireFox icon three times - three FireFox windows...

Not at all.

Just because you don't understand some information, it's not
automatically nonsense.

Yes, three windows, but one application instance.

Open the process list in the task manager and count it, if you like.
