I have a last question concerning this topic :
Suppose I would tell you : "In front of my internet
server I have a WC in transparant mode and it works.
the Internet DNS points the URL to the TP-WC and the
TP-WC caches the content of the server. Since there is
only one webserver (apart from DOS attacks, and
operating system security) I do not need a Firewall to
divert traffic.
Is there any reason why I should change the
transparent WC into an accelerator mode WC and why ?
What benefit would an accelerator WC give me above the
transparent one ?
In squid specifically:
http_port 80 vhost
+ Host: header de-referencing for better www simulation
+ full WWW-Authentication (not just Proxy-Authentication)
+ Support for IE reload bugs.
+ PMTU discovery
+ in-transit port alteration (vport)
http_port 80 transparent
-- disabled all authentication
+ performs NAT lookup every request
-- disables PMTU discovery
- may simulate the client IP (tproxy)

The different modes is not about performance but
different use cases.
accelerator or reverse proxy -> Squid sits infront
of your own web
server (or one you host), offloading traffic from
the web server. The
DNS is registered so that Internet users visiting
your site contact the
Squid server.
transparent interception -> Squid sits in the path
of your LAN users
outgoing web traffic and port 80 traffic is
transparently diverted to
the proxy by firewall rules. This is a workaround to
make all LAN client
HTTP traffic go via the proxy even if they haven't
configured the proxy
settings correct.
normal proxy -> The clients is configured to use the
proxy, either
manuall or via automatic means such as WPAD.
accelerator more is Internet users -> your web
server.
transparent interception and normal mode is your
local LAN users going
out to random web servers out on the Internet.

Please use Squid 2.6STABLE17+ or 3.0STABLE1+
There are serious security advisories out on all earlier releases.
