I'm going to bite on this... feel free to correct me.

Not sure what "passive" and "active" mean in this context. Squid caches
the responses to requests that are made through it, so if someone else
makes the same request again (and it meets the criteria for using the
cache), they will get the data quickly from the cache. If by "active
caching" you mean read-ahead, then no. That sort of thing is considered
anti-social by many web masters.

Yeah. But it still works good without it.

Not sure what you mean by this.

While squid can be used in a load-balancing configuration, it doesn't do
it by itself. There has been good stuff on the mailing list on this
subject... check the archives.

Don't know what this is.

How is this different from above?

Yep.

Yes (if this means what I think it means).

Is this different from "Reverse Proxy"?

Yes.

Yes (not pipelining, though).

Yes.

This is an operating system feature, not an application feature. Squid
only forms the "web proxy" part of the firewall equation. A common way
to use squid is with an internal network of machines that don't
otherwise have access to the Internet. With this configuration, you
don't need a firewall at all.

Yes.

No (this is a lower-level thing, usually done by routers AFAIK).

Yes.

Yes.

Not sure.
> Real Time Alerting
Alerting to what? This sounds more like something you'd want from a
firewall than a web proxy.
> Packet Logging
Again a firewall feature. Squid just logs web requests.

Yes.
> Domain Filtering
Yes.
> Resists IP Spoofing
No. This is a router/firewall/operating system feature.
> Resists Satan & Iss
To the extent that is does not permit itself to be hacked by them, yes.
> Virtual Private Network
I suppose, if one were to stretch the point, you could tunnel a VPN
through the CONNECT feature of a squid proxy. And Squid will work with a
VPN if you have one set up. But you need seperate software for a VPN.
> Network Address Translation
Operating system/router feature. Squid is compatible with NAT setups,
though.
> Transparent proxy
Yes, together with the correct router/operating system configuration.
Problematic, though.
> Single User Logon
Don't know. As I understand it, Squid does support add-on authenticators
which can be used to make it work with arbitrary authentication systems.
> Content Filtering(Pattern site blocking)
Yeah (but it can only filter on URL, not on page contents).
> Content Filtering(Domain Site blocking)
This items follows from the previous.

Not sure what you mean by this. Probably not.

No.

Yes (but I haven't tried it myself)

Yes.

Yes.

Don't know what this is.

No.

No..

Yes.
> IPX-to-IP gateway
Not relevant to a web proxy.

No, but works with operating-system level auto-dial.
