[squid-users] Yet another "Invalid URL" question

Am trying to set up a separate box (with two NICs) as a
firewall/filter using the following configuration. When Squid was
running without Dansguardian, and I connected a laptop to the second
NIC and pointed the laptop to Squid, everything worked fine. With the
iptables set and Dansguardian running (and the laptop configured just
normally), however, when I enter anything into the laptop's browser, I
get an error message, from Squid, saying the URL is invalid, and the
URL that it says it is trying to use is the URL I typed, without the
domain info. Thus, if I ask for "www.google.com/" it shows "/"
instead. If I try something like
"search.lycos.com/?query=test&x=0&y=0" it shows "/?query=test&x=0&y=0"
instead. I have seen some chatter about this type of thing on Squid's mail
list, but, again, the Squid-only operation did not encounter this
problem, so it could be something to do with Dansguardian, but I'm asking here,
as well as in the Dansguardian group, in case anyone here could be of
assistance (and because nobody has responded, at all, in the
Dansguardian group).

The configuration I am trying to use is listed below, but here are a
couple of notes, before I just paste it all there. First, the main
set of instructions I was trying to use for this were from:

http://www.spencerstirling.com/computergeek/dansguardian.html

However, it appears to be a bit older, and mentions Squid options that
no longer appear to be valid (e.g. "httpd_accel_host virtual"). It
also says to use "http_port 127.0.0.1:3128" but the discussion of the
"invalid URL" problem in the Squid mail list suggests "http_post
127.0.0.1:3128 transparent" instead. Thus, I'm sure that the mismash
of settings I am using is, somehow, the cause of the problem, but I
lack the networking experience to tell just WHERE the problem occurs.

Here, then, is the rest of the configuration information:

Linux: Debian 4.0 r3 i386
iptables: 1.3.6
Squid: 3.0.PRES
Dansguardian: 2.8.0.6-antivirus-6.4.4.1-2
(Squid and Dansguardian installed via Synaptic Package Manager)

Since the configuration files are large enough that their full text
would cause the list server to truncate this message, I have posted
them to MediaFire. Here they are:

firewall.sh: http://www.mediafire.com/?zvb2gjj99d9

dansguardian.conf: http://www.mediafire.com/?gucyirxttdb

squid.conf: http://www.mediafire.com/?22txgzjdcez

Thanks!
