Well sessions can of course be implemented in several ways.  Obviously only a key can be sent back and forth to the browser, which is then used to lookup the complete session on the server (either by way of a database, filesystem, etc).  If there is more than 1 web server, though, storing things on the filesystem won't work.  So I've also seen people actually store the session data in a cookie which is then also passed back and forth.  I generally never think this is a good idea, and would rather move things to a database.
