Not with squid. With MS proxy server or something, you might have to
buy the required number of client licenses.

Cache means that squid will store pages that it fetches, and will
serve from the cache instead of actually retrieving repeatedly from
the website, if it feels that the page has not changed since it last
fetched it. This can considerably reduce loading time of many web
pages with static content, and also software downloads. Squid is
indeed a caching proxy server.

Nothing, but I don't think that apache does caching. Also, use the
tool designed to do your work, and not a patchwork on a tool that does
something else...

squid comes with a program called cachemgr.cgi, which can be used to
administer it via a web interface. But its config file (and indeed,
the whole package) is so well documented that I have never felt a need
to use it.

Good enough - but I'd suggest dedicating a machine for the proxy
server. Also, devote lots of space for the cache - maybe one GB or so.

Hmm... squid is completely acl based. You can authenticate via a
variety of modules that come with squid - even from databases, and if
you use PAM, the full functionality of PAM also can be used
(authenticating from NT etc.). Restrictions/Access can be based on URL
regexes, client IP address, client browser software (;-), method of
access (GET, POST, CONNECT etc.), protocol (http/https/ftp/gopher),
date/time and a variety of other things.
neeraj> Any link /suggestions would be of great help .
http://www.squid-cache.org and http://squid.nlanr.net are the official
pages of squid. The mailing list archives has a wealth of information
as well.
