[Facebooker-talk] how do I use the new infinite sessions?

[jeff barrett]

I've got an existing webapp that I'm integrating w/ Facebook.  I'm trying to wrap my head around a few things and I'd appreciate some pointers.

It sounds like I would need an infinite session if I want to post a newsfeed item to facebook when I don't have a "recent" session.  Have I got that right? 

This post (http://developers.facebook.com/news.php?blog=1&story=116) led me to believe that in the "new" version of facebook the only way to get an infinite session would be for someone to check the "Keep me logged into <app name>" checkbox at "Log in to the <app name> application?" dialog.  Have I got that right?

If the above is true and someone did check that box at login, how would I know that they did and how do I grab that infinite session key?

Let's say someone logged in to my application via FB but didn't check the "Keep me logged into <app name>" checkbox.  Is there a way recognize this state to drive them back to that login page later?

TIA for the help.
