Hi

Sorry, cause I don't have enough time, to look at your problem now, but I
wrote this function a few months ago, it seems to works fine, so If you want
to give it a try, It may be useful for everybody

This function joins both tasks in one, it closes the session, calling
page_close(), and automatically redirect to the URL you pass in, everything
I do, is calling it in every page I want to add a logout feature, tipically
my scripts looks like:

page_open();

// the line below runs everytime you enter this page, but it will do logout,
only in case it gets the $logout==true, i.e taken from GET_VARS
//
page_close_logout($url,$query_string,$logout)

// Your script code

page_close()



function page_close_logout($url="",$qstring="",$logout=false){
        global $auth;
        global $PHP_SELF;
        global $QUERY_STRING;
        if($url=="") $url = $PHP_SELF;
        if($qstring=="") $qstring = $QUERY_STRING;
        if(is_login() && $logout==true){
                modify_url("$url?$qtring","logout","");
                $auth->logout();
                page_close();
                // echo "$url?$qtring";
                header("Location: $url?$qtring");
        }
}

function is_login(){
        global $sess;
        global $auth;
        $uid= isset($auth)?$auth->is_authenticated():false;
        return ($sess->is_registered("auth") and ($uid!=false) and
$uid!="form");
}

Hope this help
Lazaro
