When I run phpinfo(), I see an entry for _SERVER["HTTP_COOKIE"], so it exists. _SERVER['THE_REQUEST'] is not there, but it looks like you could replicate it manually using something like this:
$_SERVER["REQUEST_METHOD"] . " " .
$_SERVER["REQUEST_URI"] . " " .
It appears there are also equivalent values in the array of $_ENV variables.
Depending on how you want to see the cookie data, you might find the $_COOKIE array useful.
