Dialup connections can be frustrating. Squid, a very popular piece of
'net caching software does a lot to cut bandwidth demands, but it isn't
built for dialups. This article shows how to change that:
"One of the more frequent requests on the Squid mailing lists is for help configuring Squid to operate well on dial-up or demand-dial networks.
Offline mode will function for some of these networks, but is far from ideal. Unfortunately many of the features of Squid's offline mode appear to
have largely vanished during the development of the Squid 2.x series. In the 2.3 STABLE 4 version, the offline mode has nearly no effect at
all.
Squid can be patched to work well with dial-up and other intermittent connections.
Having a cache on the intermittent side of the link can take some of the curse off
these connections, providing access to cached information and reducing
bandwidth use on the link. Unpatched, Squid can work reasonably well on
dial-on-demand connections, but dialing in each time it needs to resolve a query
can become expensive.
Squid is designed for permanent connections. Making Squid work on intermittent
connections requires changing how Squid handles stale web pages and stale
DNS lookups."
