It makes absolutely no difference if it lives in the session, you still can
only modify it by calling a URL on the server. By the time the user sees
the template, it is rendered to just HTML. The HTML in the user's browser
does not have access to the methods of a session object which lives on the
server. The only thing you can do from the browser is call a URL.
Now, if you like, you can call that URL via Ajax, so the user doesn't
actually have to navigate to another page: but the fact remains, the only
way to modify something on the server - whether in the session, the db, or
even a file on disk - is by calling a URL.
