Sessions are acting strangely

Hi there, Im looking for ANY help regarding his problem - I find this interesting to say the least. I recently switched to a new hosting company - they are running php 4.1.2 - register globals is ON. the sessions automatically expire without closing the window. if you load index.php and wait past 30 seconds - the session variables are empty - Sometimes - although not reliably - if you wait another 30 seconds - the variables are back? - this is very strange? - here are the files I have setup to illustrate this problem. Im using the default php-ini file - so no weird session expires or garbage collections stuff. Ive set up 3 basic files: ------------------------------------------------ index.php: <?php session_start(); session_register('var1','var2'); $var1 = "cat"; $var2 = "dog"; echo "Click <a href=\"sess2.php\">here</a> to view the session vars on page 2"; ?> --------------------------------------------------- sess2.php: <?php session_start(); echo "Var1 = $var1, var2 = $var2"; echo "Click <a href=\"sess3.php\">here</a> to view the session vars on page 3"; ?> ------------------------------------------------------ sess3.php: <?php session_start(); echo "Var1 = $var1, var2 = $var2"; echo "Click <a href=\"sess2.php\">here</a> to view the session vars on page 2"; echo "<br><br><br><br>Click <a href=\"index.php\">here</a> to go back to page 1 to reset the session vars"; ?> -------------------------------------------------------- Does anyone know if 4.1.2 had any session bugs?
