Exactly. There is such a thing as local, but it only lasts the
session. Therefore, a local cache should not persist beyond the
session. You could possibly supplement that with a smaller (as server
diskspace is a hell of a lot more expensive than roving workstation
diskspace, generally[0]) server-side cache with just the most accessed
stuff in it - impractical, and a (preferably transparent) proxy cache
server is a lot easier to administer.

[0] I'm thinking of an environment like my Uni where the student's
computers were low-grade P-I's with 2G of disk space each. On local
disk: Nothing. These babies were actually disabled in the BIOS.. well,
right until some knowledgeable people (and I'm not admitting anything)
enabled them. The library, which had much newer P-II 266's, 300 of
them, had Ghosted installs of Win98, Word, Nutscrape, the works,
taking about 500M or so out of the 4G disks. Booting them up via the
network card Bootrom (was optional) would boot them to a server that
would automatically Ghost the install on them. Very clever idea, I
think: it allows you basically not to care very much what someone does
with his PC, as long as the firewall isn't breached. And, well,
securing Win98 installs in a university of 16000 technical students,
of which the biggest geeks will be found at those computers... and
also still allowing floppy _and_ CDROM access.. Impossible task,
basically. Wow. Footnote twice the size of the post. Good work.[1]

moderation?
