Storing Session Across Pages

SketchySteve has asked for the wisdom of the Perl Monks concerning the following question:

Hello there,

I have been trying to implement an idea of an account into AWStats. For this I want to use session so we can store a name and url in a session when a user logs on.

Could my problems be down to using IIS? Also "{Directory=>'/tmp'}", I have tried creating this in the website root and the drive root but nothing ever gets written with my example - any ideas?

I have tried many variations of scripts with no luck. I just cant maintain states across pages. My latest attempt is below...

Page one...
use CGI::Session;
use CGI;

my $cgi = new CGI;      
my $session = new CGI::Session(undef, $cgi, {Directory=>'/tmp'});    
$cookie = $cgi->cookie(CGISESSID => $session->id );
print $cgi->header(-cookie=>$cookie);


$session->param('f_name', 'Sherzod');


print '<a href="session2.pl">Page 2</a>';

Page 2...
use strict;
use CGI::Session;
use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
use CGI;


my $cgi = new CGI;      
my $session = new CGI::Session(undef, $cgi, {Directory=>'/tmp'});    
my $cookie = $cgi->cookie(CGISESSID => $session->id );
print $cgi->header(-cookie=>$cookie);


my $name = $session->param("l_name");

print $name;


I found one example on the web which isnt working and comes up with "Y
+ou have not logged in". 

Page one...
use CGI;
use CGI::Carp qw/fatalsToBrowser warningsToBrowser/;
use CGI::Session ( '-ip_match' );

$q = new CGI;

$usr = $q->param('usr');
$pwd = $q->param('pwd');

if($usr ne '')
{
  # process the form
  if($usr eq "demo" and $pwd eq "demo")
  {
      $session = new CGI::Session();
      print $session->header(-location=>'index.pl');
  }
  else
  {
      print $q->header(-type=>"text/html",-location=>"login.pl");
  }
}
elsif($q->param('action') eq 'logout')
{
  $session = CGI::Session->load() or die CGI::Session->errstr;
  $session->delete();
  print $session->header(-location=>'login.pl');
}
else
{
  print $q->header;
  print <<HTML
      <form method="post">
      Username: <input type="text" name="usr">

      Password: <input type="password" name="pwd">


      <input type="submit">
      </form>
HTML
}

use CGI;

$q = new CGI;

if($session->is_expired)
{
    print $q->header(-cache_control=>"no-cache, no-store, must-revalid
+ate");
    print "Your has session expired. Please login again.";
    print "<br/><a href='login.pl>Login</a>";
}
elsif($session->is_empty)
{

}

On page 2, you're supposed to read the session ID from the cookie and pass it to CGI::Session->new().	[reply]
