PHP and ORACLE conection error

hy, i'm having a problem with my project.... i have an oracle server on a computer named oracle and in apache htdocs files i have a directory special for my project... 1 in that dir i have a html file named index.html here i get the username and the password and post it to the validate.php file in the validate.php file: the first i have is <?php session_start(); header("Cache-control:private"); ?> then 1. i get the variables $name=$_POST['username']; $password=$_POST['pass']; 2. i register the variables session_register("name") and session_register("password"), 3. i verify if they can acces to the database if( ociplogon($name,$password)) $ok='true'; else $ok='false'; 4. in the body of the validate.php i have a script in order to load a new page <script> var ok=<?php echo $ok; ?> if(ok==true) window.location.href="good_page.php"; else window.location.href="error.php" window.reload(); </script> well that's it.... it works but not fine....i know it isn't the best way but it worked .... till some days i have any problems but since today i don't know what is happening... sometimes it works loading the good_page but sometimes it loads the error page.... i think it is something with authentification and session but i need a solution quickly...i have no time to rethink all... if you have a solution or another type of making all i have made send me a reply thanks a lot... cybercop78 http://www.idilis.ro - Stiri, e-mail gratuit, download, SMS, server de counter-strike, hosting gratuit, servicii internet...
