Hi,Renze i tried u'r last solution first.But it is acting as
same .no change.
After that i tried u'r first solution i.e removing include and adding
header("Location....");
It is giving the following error message.
Warning: Cannot add header information - headers already sent in
c:\www\authentication.php on line 40
Thanks and regards

Subject: Re: [PHP] Re: prob with session
start
I think I know what it is. The construction I mentioned to
avoid the
reloading used three pages to login: the login-page, the
validation
page and then some page that produces output to the
user.
What you do, is include that output page in the validation
page
(authentication.php). You shouldn't do that. Instead of
the
include('super.php') you should use header("Location:
super.php")
and instead of include('ordinary.php') you should
use
header("Location: ordinary.php"). If you
include
super.php/ordinary.php you still don't leave
authentication.php.
That means that one can still reload
authentication.php. Then the
browser asks for resubmitting the form. If you
use header() instead
of include() you actually leave authentication.php and
go to a
different page. The user can ofcourse reload that page, but
that
page wasn't actually the result of a form-submital so the page
will
then just be reloaded and no information will be resubmitted.
Even
if one pushes Back from that page, he/she will not go back
to
authentication.php but to login.html. And gone is your problem.
I
think this should be your solution...
Oh... btw:
in
authentication.php:
session_register('$emp_id');
should
be:
session_register("emp_id");
and in logout.php:
session_unregister($emp_id);
should be
session_unregister("emp_id");
