Hi,
The content of $_SESSION is stored serialized in a file, that is stored
in the directory given in php.ini. Often some tmp directory on the machine.
Find it by using php_info().

Use print_r() for this.
Don't forget to wrap the HTML <pre> around it.
So:
echo "<pre>";
print_r($_POST);
echo "</pre>";
