G'day everyone,
I'd like to post some current "internet" caching stats for corporate
and ISP forward caching.
Our mgr:info come in only from one proxy of our University.
I'm interested in traffic throughput, request rate, byte and
hitrate statistics.
(I'm basically looking to build a page or two about this on the
Squid website to counter the current view that there's no point
in running forward caches in the real world today. I really
could do with all the help I could get on this, as I don't
currently run forward caches in an ISP environment..)
Adrian, I couldn't imagine our Internet connection without a forward
proxy caching. We use several features of squid and another products
integrated with squid to give our users a higher-quality Internet
experience.
