Yeah, this is correct. Sessions in PHP are a mechanism to store  
persistent data across visits. Where this data is stored is subject  
to the developer, but the standard place is in session files on the  
server. One can also store it in a databaase or write a custom  
storage handler for it. But usually, when the session ends the  
session data is written to the session file on the server, and when  
the session starts the data is read from the session file and then  
available in $_SESSION. The only thing that's passes around to the  
client and back is the session id, regardless if you use cookies or  
the urls to pass the session id.

But yeah, it's pretty well explained in the manual.
