Description:
------------
When i use an include/require to load a success page ( in this case, the list the "add" was called from ) the session variables are not present. I have session_start() on each page, and if i call the pages directly ( from a menu ) the sessions remain. This happends every time i do this. I dont know if its a bug, but i have to control over the webserver as its a web hosting plan.

Reproduce code:
---------------
<?php
session_start();
if (isset($_POST['submit']) {
  //do saveing stuff
  $OK = true;
}
if ($OK) {
  //display form, submit button at bottom
  //page calls itself, or rather, blank action
}
else {
  require_once('list.php');
}

Expected result:
----------------
the original listing come back up, with the new addition.

Actual result:
--------------
the frame/table for the expected result, empty due to session vars not relaying the clientid or any other for that matter.
