Problem is in session identification.
When you start a session, it gets unique identifier, which is passed to
your browser (in cookie or, if cookies are off, in GET parameter). Value
stored in the session is saved on the server and next time you call
session_start, PHP finds it on the server according to this identifier.
For the third script the calling client is not your browser, but cURL
client on the server. However, it doesn't know the session identifier,
so the session is empty.
What you need is to pass session identifier to the URL called by cURL in
second script as a GET parameter.
