hi.. a newbie here
a user fill up a form with username and password
passing the form through 'POST'
a session was created,
a user login,
a user logout + session destroy,
but after that if the user press back button
on the browser seems like the browser
will repost the username and password back
through the form so the user need not to reenter
his/hers username/password
how to avoid this problem?
thx
