& also sometimes the need arises in a network(limitations) where one
needs to prefetch the site, irrespective of what the site(server) tells
squid _NOT_TO_CACHE_ .. here in INDIA many network are very low on
bandwidth, spl the cybercafe & as consultant, we face comparison with
other caches(softwares) that perform such task.. we in our ISP setup use
squid & am personally with squid for last 2+ years now with very good
performance..
But as Ben says, & i agree too, that sometimes the need arises to have a
site cached irrespective of anything else(except the refesss patern
ofcource)..
Squid developers, this is just a thought, how about a prefecting(admin)
option in squid ?.. for eg to tell squid to prefect www.foo.org with
depth 5 in every <n> days at <x> time of the day ?
the idea behind is that the request for www.foo.org being serve by squid
without going to net in the duration of before <n> days. this might/will
improve caching performance...

i dont want to sound a hardcore & blind supporter of squid but its true
till now i feel, squid is better that any other caches we have seen or
worked with..

Yes with Ben i say too----Thumps up to squid developers.. !! :-)

thanx
