I consider a session timeout to be a failure of SC 2.2.1.    I agree we could be more clear about it applying to session timeouts.

Many sites fail 2.2.1 for timing not adjustable because sessions time out without warning. For remediation, I generally suggest they provide a modal dialogue box with "do you need more time" with Yes/no buttons. However, thinking this through I'm wondering if we should perhaps provide a bit of guidance that this not be a failure in *all* situations. It is one thing to have a time limit on a task... that should have a requirement on 2.2.1.  but a time out from inactivity, perhaps should be treated differently. If the timing is measured on the back end it could be a problem because the person might be working away and the application doesn't know it, then times them out...but if the application is listening to activity in the DOM on the client side, any activity should keep the connection open...Maybe we could consider 2.2.1 met automatically if the listening is happening on the front end, and it keeps the session active as long as there is a reasonable amount of activity.... wondering what other think.
