my module is running fine but there are errors
1.when i use my module in cgi program i am not able to the retrieve username where as if i paste the script in the cgi program i am able to retrieve the username

note

the module contains the same script which i am pasting . i just made a new module of it so that i can call it easily where i need session variables

2.where ever i use my module in a cgi script it creates a new sesssion instead of tracking for the existing one

please let me know if i am making any mistake or my approac is wrong

do i use cookies to accomplish the same

module is like this

package raman;


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


 



our @ISA       = qw(Exporter);
my $session_dir = "C:\\raman";


use constant SESSION_COOKIE => "MY_SITE_SIDE";

$sid = $cgi->cookie(SESSION_COOKIE) || $cgi->param("sid") || undef;

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

                                     
                                        Directory=>$session_dir
                                    }
                    ) 
#incase of any error the session close giving an error
                    or die $CGI::Session::errstr;

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

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

#print $cgi->header;





#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
$x= $session->save_param($cgi);
