Problem with browser tabs and sessions

[ualex]

I have a application make in jsp tomcat 4.1.

the customer fill some forms and the data in store in session.

The problem is that if customer open new tab(ie or firefox) and see
info another product when he change for tab initial and submit, the
system will rise error because some data of session was changed.

How i can fix it ?

I need each tab have your new session, there are any config in tomcat
for make it ?



thanks a lot
