This is the same title as a previous question but the error occurs in different circumstances. I am a complete newby with CGI and PERL and was just looking to debug a CGI script.

  my $cookie1 = $cgi->cookie(-name => "login",
                        -value => "",

                        -value => "",

  my $cookie = $cookie1."\nSet-Cookie: $cookie2"."\nSet-Cookie: $cooki
+e3\nSet-Cookie: $cookie4";

  print $cgi->redirect(-cookie => $cookie,
                       -uri    => "$PROTOCOL://$ENV{HTTP_HOST}$ENV{SCR

                      );

  return;

This is to log out from the script and redirect to the previous screen.
