ZF2 - How are you supposed to access session vars in a session container?

[Moksha]

I create a container like so:\[code\]$frontend = new SessionContainer('frontend', null);\[/code\]I set a variable like so:\[code\]$frontend->offsetSet('foo',$bar);\[/code\]My question is, when you need to access this somewhere else, are you really supposed to instantiate a new SessionContainer with the same key everywhere you go and grab the var? Or, is the session data being passed around in another variable available in the controller or something?
