I downloaded and installed Smart Cache 0.86 from Hobbes yesterday
(http://hobbes.nmsu.edu/pub/java/apps/internet/www/), mostly just to see
what it does. Smart Cache is a web cache / proxy server and I'd like to
know why someone might use it.
The author wrote it because he is on a pay-by-the-minute dialup line and
didn't want to pay for idle modem time; he clicks on everything he wants
to view to get it into the cache, then disconnects and reads everything
from the cache. You tell your browser to connect to Smart Cache instead
of the Internet, and Smart Cache gets everything for you and keeps it
cached for a while (the default is two days). I guess this would also
be handy for those who travel with a laptop; you could download all
kinds of web articles you wanted to look at and then read them on the
train, plane, carpool, nuclear bunker or after you'd hiked up a mountain
somewhere.
I'd like to know some other reasons for using a cache or cacheing proxy
server. Is anyone else using SmartCache or a similar cache? And can
you tell me why you are using it? I'm looking for other reasons to use
such a cache. One use I can think of is to use wget on a one-hour loop
to get my favorite web pages which will put them into the cache, so when
I actually look at them there's no wait for them to download -- they
come right out of the cache. What other ways might someone use Smart
Cache?
The Smart Cache documentation is excellent and I highly recommend it
just for the reading if you have any interest in web proxy cacheing --
think of it as a free book.
It worked fine (it's still beta at version 0.86) except for a
divide-by-zero error when I decided to see what would happen if I set
the cache size to zero. (I haven't tried a negative number yet.)
