Background: In our utility program, we have just normal perl pages. There are two type of users, Admin and User. If they are trying to login, I need to save the value in session object and redirect to another page. 1. I tried to use just cookies, without using sessions, Here the problem is I can able to set the value first time. But I can't able to delete that(when user logouts, I am keeping empty string there)..my system is behaving something strange. This is simple example, but misbehaving. If I refresh the web page again, then the new value is appearing. 2. By using session, setting value is no problem, but the redirecting, just printing the url on web page. 
my $session = session_header;#---by using CGI::Session;
if ( $query->param("frmsubmit") ) {

$uname = $query->param("uname");
$pwd = $query->param("pwd");
if ($uname eq "AA" && $pwd eq "AA") {
$session->param( "usertype", 'admin' ); # store into the session:
my $c = new CGI::Cookie(-name => 'plcuser',-value => 'admin', -expires
+ => '+20m');
print "Set-Cookie: $c\n";
print "Location: $rdurl\n\n";
#print $query->redirect($rdurl);
}
