Description:
------------
Using Apache/1.3.29, the header("location...") feature doesn't work after saving a session variable.  I have two php scripts, login and logout.  In logout, I destroy the session with session_destroy() then use the redirect to get back to the starting page.  This works fine.  In the login script, I verify credentials then set a session variable to indicate the user is logged in, then try the exact same redirect to the index page, this doesn't work. I've tried using "Location: http://www.google.com/" which doesn't work either.  I've also entered the absolute paths to the proper scripts on my own site with the same result.


Reproduce code:
---------------
logout.php - works
------------------
<?php
if (!session_id()) session_start();
if (isset($_SESSION['loggedIn'])) session_destroy();
header("Location: index.php");
?>

login.php excerpt - broken
--------------------------
if (!strcmp($row['password'], $thisPassword) && ($row
     ['type'] == 1)) {
  $_SESSION['blah'] = true;
  header("Location: index.php");
  exit();
}

Expected result:
----------------
I expect to be redirected to the page indicated in the Location header.

Actual result:
--------------
The system seems to ignore the header script altogether, displaying a blank screen when it hits the exit() call.
