## step 1. take the username and password from the form
## step 2. query the mysql db and check to see whether the password  is good for the username
## Now create session id and set cookies .....

                $cgi = new CGI;
                $session = new CGI::Session("driver:DB_File",undef,{Directory=>'/tmp'});
                $sid=$session->id();
                $session->param("userid",$newuserid);
                $cookie=$cgi->cookie(CGISESSID=>$session->id);
                print $cgi->header(-cookie=>$cookie);
                $cookieuserid=$session->param("userid");
## now we can display anything to them because they just logged in
