You might think so, since when you first connect to the GIFT server, you
pass an MRML message like:

     <?xml version="1.0" standalone="no" ?>
     <!DOCTYPE mrml SYSTEM "file:/*************/share/mrml.dtd">
     <mrml session-id="12345">
     <open-session user-id="User"
session-name="--feedback-client-session--"/>
     <get-algorithms />
     <get-collections />
     </mrml>

The server, however, ignores the session-id passed in, and returns
another (valid) one to you. When you think about it, this makes sense,
as otherwise the server could not guarantee unique session-id's.

There is nothing to stop you using your php session id as the key for
your state data though - you can use anything you want, since it's local
to the server where the interface runs.
