PHP not saving sessions on subdomain, ok on domain
We have a CentOS 5.4 server serving a number of our websites. The server is managed by Plesk 9.2.3. Our websites are developed in php.
We have our main domain ourapplication.co.uk in /var/www/vhosts/ourapplication.co.uk/httpdocs, and our subdomain api.ourapplication.co.uk in /var/www/vhosts/ourapplication/subdomains/api/httpdocs
The following pages are in BOTH locations:
davidstest1.php
<?php
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<body>
<?php
echo "This is Davids Test 1. It will set SESSION['davids']='davids variable set' and then link
to davidstest2.php<br />
davidstest2 wil then do a session_start() call, and attempt to display SESSION['davids'] <br />";
$_SESSION['davids']='davids variable set';
?>

davidstest2.php
<?php
session_start();

echo $r;
echo "<br /></pre>";
?>
<a href="davidstest2.php">davidstest2.php</a>

in the MAIN domain, davidstest2 returns
This is Davids Test 2. It will do a session_start() call, and attempt to display SESSION['davids']
Session in
Array
(
[siteMode] => none
[davids] => davids variable set
)
davidstest2.php
in the api SUBDOMAIN, davidstest2 returns
This is Davids Test 2. It will do a session_start() call, and attempt to display SESSION['davids']
Session in
Array
(
)
davidstest2.php
Obviously, something in the Apache config or the Php config is wrong, as the session variable should be stored for both domains
Relevant phpinfo() reports:

Any ideas where to start looking?
Set session.cookie_domain to .ourapplication.co.uk (note the dot at the begin) to have the session cookies be valid for ourapplication.co.uk and all its subdomains.
session.cookie_domain should be set according to cookie domain setting explained in http://php.net/setcookie
session_set_cookie_params() function is often used for this
