You should post short but complete scripts that demonstrate your issue.

Why do you have that continue statement? Using it as you have shown doesn't make any sense.

home.pl
$cg = new CGI;
my $cookie = $cg->cookie(-name => 'id',
                          -value => $user,
                          -expires => '+2m',
                          -path => '/');
       print $cg->redirect("wel.pl");
       print $cg->header(-cookie => $cookie);


wel.pl
my $cookie = $cg->cookie('id');
if ( ! $cookie )
{
  print $cg->redirect("home.pl");
}
elsif($cookie) {
#continue to the site if cookie exists 
}

i have tried other way bt still failed bt i cant understand why its not working, when i put the user and press Submit button it reach at wel.pl and redirect me back to home.pl

home.pl
$cg = new CGI;
my $cookie = $cg->cookie(-name => 'id',
                          -value => $user,
                          -expires => '+2m',
                          -path => '/');
       print $cg->redirect("wel.pl");
       print $cg->header(-cookie => $cookie);


wel.pl
my $cookie = $cg->cookie('id');
if ( ! $cookie )
{
  print $cg->redirect("home.pl");
}
elsif($cookie) {
#continue to the site if cookie exists 
}

Please show the complete home.pl script, including the Form you are submitting. My guess is you should be creating the cookie in the wel.pl script using the parameter sent from the form in the home.pl script.
