+@node Agent as Cache
+@subsection Agent as Cache
+
+When Gnus is plugged, it is not efficient to download headers or
+articles from the server again, if they are already stored in the
+Agent. So, Gnus normally only downloads headers once, and stores them
+in the Agent. These headers are later used when generating the summary
+buffer, regardless of whether you are plugged or unplugged. Articles
+are not cached in the Agent by default though (that would potentially
+consume lots of disk space), but if you have already downloaded an
+article into the Agent, Gnus will not download the article from the
+server again but use the locally stored copy instead.

+This behaviour can be controlled by @code{gnus-agent-cache}
