[Novalug] Arlington County Public Schools website: Windows only? (2nd attempt)

Thanks all for the responses. Given everyone's reply I'm thinking it
may have something to do with my FIOS router (though the people who
got it working under linux all seem to be using firefox 1.5 so I'm
going to try that when I get some time.)

The OS/Browser combos I've tried:

The working:

XP + Firefox 2.x

The not working:

Gentoo + Firefox 2.x (both with & without User-Agent spoofing)
Gentoo + Opera 9.25 build 687 for linux (both with & without
User-Agent spoofing)
Gentoo + Perl + IO::Socket replaying the sniffed working (XP+Firefox)
request exactly

Mac OSX 10.3.9 + Firefox 2.x
Mac OSX 10.3.9 + Safari (whatever version was the default)
Mac OSX 10.3.9 + Internet Explorer 5
Mac OSX 10.5.1 + Firefox 2.x
Mac OSX 10.5.1 + Safari 3
Mac OSX 10.5.1 + Opera 9.25

I've sniffed the "not working" traffic from the Gentoo box, I get a
response that is 8 bytes exactly and then no more. The bytes seem to
be dependent on the request structure -- i.e. the same request
generates the same bytes from the gentoo box (however the bytes DO NOT
match the 1st 8 bytes of the working response even though the request
from the Perl script is identical at the byte level.)

Cheers,
  Craig P
