session handling help please....

[Anon]

hi friends,
I have som eproblems with session handling
iam using php4 and mysql
i have used session_start(),session_register() functions in my php files .
when a user logs in and he views the pages and he logs off(he does not close the browser explicitly)
then if another user logs in he is taken to teh saem page as by the previous user
i mean to say taht the session for the first user itself continues with teh second why?
also by clicking back button of the browser he can very well access the first user's pages too
in short there is no session handling taking place
what could be the problem?
do i have to include those functions in every page?
how do i decide which variables to ber registered
as of now i have registered only the loginid and password
iam confused
any help would be apperciated
regards
Roopa

hi,

make sure session data is wipe before reauthentificate ...
what kind of data do you save to the session
to the recognize the user ?
it seems as if this data isn't correctly reset ...
bye,
