can you please help me how do i move with it . what concept should i apply . i have read through the cgi::session doc in detail

my code for session variables is as below

#!c:\Perl\bin\perl.exe -w

use strict;
use CGI::Carp qw(fatalsToBrowser);
#die "Bad error here";
use CGI;
use CGI::Cookie;
use Data::Dumper;
use CGI::Session;
my $cgi = new CGI;

my $session_dir = "C:\\raman";

#Generating  a new session 

use constant SESSION_COOKIE => "MY_SITE_SIDE";

my $sid = $cgi->cookie("SESSION_COOKIE") || $cgi->param("sid") || unde
+f;

my $session = new CGI::Session("driver:File", $cgi,
                                    {                                 
+             

                                     
                           #giving the directory where the session var
+iables will be stored 
                            Directory=>$session_dir
                                    }
                    ) 
#incase of any error the session close giving an error
                    or die $CGI::Session::errstr;

my $cookie = $cgi->param(-name => SESSION_COOKIE,
             -value => $session->id,
                       #sessiion expires after 3 hours
            -expires=>"+3h");

$cgi->header(-cookie=>$cookie);

#print $cgi->header;
#print $cgi->start_html;
#print <<HERE;
#<b>jkasgdf</b>





#print "Your session id is ", $session->id();
  

# A cookie is being created which is then being send to the user brows
+er

     

$session->param('username', 'raman');

#$session->save_param($cgi, ["username", "password"]); 
#print $session->param('username'); #prints raman

# this line saves all the available/accessible CGI params
my $x= $session->save_param($cgi);
#print $x;

print "\n";

#returns the time 
printf("Session was created on %s\n", scalar localtime($session->ctime
+));


#printf ("Session login time ", localtime( $session{_session_ctime}));

#using data:;dumper to print the session variables getting stored 
#print Dumper(\@variable);
