URL Rewriting - faute ==> Cookie issue - header=...

[giangcui]

J'ai réecrit URL. Ça marche. Mais au premier d'entre, il y a un cookie header=kh4kéh4é34é3é3 (changer chaque fois de l'entre) apres les address

Par Ex: www.monweb.com/monaddress.htmlheader=43854jfsdjhfg34534.

Mais si vous cliquez sur un address (un url ). Le cookie (header=...) est disparu.

Aide-moi. Qu'est ce que je dois faire pour éviter ce cookie.

Je pense que c'est la faute de session dans le fiche session.php
Code de fiche session.php
<?php
$nowtime = time();
$time_update = $nowtime - 1800;
session_name("sid");
session_name("header");
session_start();
if ( !isset($_SESSION["login"]) )
{
session_name("sid");

session_register("login");
session_register("user_id");
session_register("name");
session_register("email");
session_register("timezone");
session_register("start_time");
session_register("poll_time");
session_register("header");

$_SESSION["login"] = "not_login";
$_SESSION["user_id"] = -1;
$_SESSION["name"] = "";
$_SESSION["email"] = "";
$_SESSION["timezone"] = "+7";
$_SESSION["start_time"] = $nowtime - 1300;
$_SESSION["poll_time"] = $nowtime - 3700;
$_SESSION["header"] = -1;;
}

if ($_SESSION["start_time"]<$time_update)
{
$_SESSION["start_time"] = $nowtime;

$sess_id = session_id();
$prevtime = $nowtime - 1800;

$dbsql = new db_mysql;
$dbsql->connect();
$dbsql->selectdb();
//-----------------------------------------------------
$sql_delete = "DELETE FROM sessions WHERE start_time<".$prevtime;
$dbsql->query($sql_delete);

$sql_select = "SELECT * FROM sessions WHERE session_id='".$sess_id."'";
$dbsql->query($sql_select);
if ($dbsql->num_rows()==0)
{
$sql_insert = "INSERT INTO sessions(session_id,start_time) VALUES('".$sess_id."',".$nowtime.")";
$dbsql->query($sql_insert);
}
//-----------------------------------------------------
$dbsql->close();
}

$user_id = isset($_SESSION["user_id"]) ? intval($_SESSION["user_id"]) : -1;
$user_name = isset($_SESSION["name"]) ? $_SESSION["name"] : "";
$user_email = isset($_SESSION["email"]) ? $_SESSION["email"] : "";
$timezone = isset($_SESSION["timezone"])? $_SESSION["timezone"]: "+7";
$header = isset($_SESSION["header"]) ? $_SESSION["header"] : "-1";
?>

Merci d'avant
