[CTG] Draft 2008-11-07 / cached responses

a) Paginated responses

Section 4.1.4 discusses proxies that "paginate responses".

I am not sure what is meant with "paginated" responses; a
definition is in order. Is this a reference to range 
retrieval requests as per RFC2616 14.35.2? Or to splitting
content for presentation on a mobile device?


b) Stale data

Proxies "should provide a simple means of retrieving a fresh copy."
Is there any compelling rationale why they should not? If not,
then why not put a must?
