php Session

[eluser]elmne[/eluser]
I have a PHP session that i'm using, the Session Hybrid at codeigniter.com/wiki/Session_Hybrid/

I have a few questions about this

- Does it support a situation whereby if the user has cookies disabled, it passes the session ID using the URL?

- As the session has already defined variables that get stored to the database, when i want to add more variables or an array, do i add these using the functions and do i have to store them in the database too or are they simply stored in memory?
