I have a login script and run into an error, first heres the code:

use DBI;
use CGI qw /:standard/;
use CGI::Cookie;
use warnings;


while (! defined $cookies{'authorized'})
{
        if (param)
        {
                my $username = param('username');
                my $password = param('password');
                my $dbh = DBI->connect("dbi:SQLite:dbname=/path/to/dat
+abase.db","","");
                my $sth = $dbh->prepare('select * from useers where
                                        username = ? and password = ?'
+);
                $sth->execute($username,$password);
                my @row = $sth->fetch_array;
                if (@row)
                {
                        #login success, set authorized cookie
                        my $cookie = CGI::Cookie->new(
                                        -name=>'authorized',
                                        -value=>1,
                                        -path=>'/default/url');
                        last;                ##THIS IS WHERE I NEED TO
+ END IT
                }
        }
        print header,start_html('Login'),h1('Login'),
        start_form,
                "Username: ",textfield('username'),br,
                "Password: ",password_field('password'),br,
                submit("Enter");
        end_form, end_html; 
 
        #######this generates an infinite loop of login forms 
}

#once that specific cookie is set, i redirect
print redirect('search.cgi');

So what's happening is

while (! defined $cookies{'authorized'})
{
    if (param)
    {
         if authorized 
         {
         set cookie
         }  #end here!!!!!!!!!!!!!!!!!!
    }

#if we make it here, user isnt validated, so generate form
    generate login form
}

#now that we're out of the loop, redirect
redirect

Any way to exit out of the loop?
