Lost articles: how to keep them ?

[Xavier Maillard <zedek@gnu-rox.org>]

Hello,

I often get old expired/canceled/whatever articles in my
summaries buffers. This is shown with a 'Q' letter.

Normally I can fetch and display such articles only when I am
plugged.

How can I make them available when I am offline ? Is there a
simple way to say, cache them somewhere so that I can read them
later on ?

This is mainly to prevent loose threads. So the idea would be to
"cache" those articles (from nnweb, nntp, .. requests.)

Is Gnus configured to do so and I missed something or not ?

Thank you.
