[Q] session variables wouldn't keep contents.

Hi guys, Some php programs doesn't seem to work normally in a certain server. Those wokred correctly in my Debian box. Session is the problem. It seems that the contents of session variables disappears after reloading the php page. Here is the program. ---- test.php ---- <html> <body> <?php session_start(); if(!session_is_registered("name")) { echo "session is not registered<br><br>"; session_register("name"); $HTTP_SESSION_VARS["name"] = "test"; echo "newly registered<br><br>"; } $session_name = $HTTP_SESSION_VARS["name"]; echo session_encode()."<br><br>"; echo "session_name = $session_name"; ?> </body> </html> ---- test.php ---- Can I handle it with only php configuration file? Or Do I have to modify my php programs? In addition to this, I have a few questions about the work of session in php 4.0.4 Q1) Do I have to use session_start() explicitly although session.auto_start is set to 1 in php.ini? Q2) Do I have to use session_register("variable_name")? In my Debian woody box, it seems to run well without it. Regards, -- Chung Ha-Nyung <alita@kldp.org>
