If I start Netscape 4.7 from my desktop (2 instances of it) and go to the same page
in my webapp.  I can printout the session id on the screen.  Both browser instances
will have the same session id.
However, two instances of IE 5.0 will have different IDs.  (this is what I want).

I haven't tried creating a new window from either netscape or IE.  But if this will
cause both windows to have the same session, then this is something I need to
handle also.

I am using IE 5.0 & 5.5 and Netscape 4.7 & 6 for testing.

Right now I am NOT encoding my links.  However, if my assumptions are correct...
Encoding the links will not help me.  Encoding adds the session id as a query
string to the links.  If the two windows have the same session, then the links (in
each window) will still use the same session.

Here is the problem I am running across.   I use beans that store information
pertaining to a specific record in the database.  When a user selects an item from
a list, the bean is populated and placed in the session.  I put it in the session
because subsequent pages require this beans information as well.  However, if the
user has two browser windows running, sharing a session, it is possible for the
user to update the data for the bean in one window, and then retrieve incorrect
information in the other window.

It is very probable that a user will want to have multiple browsers running so that
he/she can compare data.

I hope you can all follow that.  I don't think that I described it very well.
