Fair criticism Alan. The file that you are viewing at
http://adamslan.shyper.com is simply posted so that folks like you can
access the html. The problem behavior occurs on my local LAN which you
can't, and won't see. As near as I can tell the file show up reliably
from adamslan.shyper.com which implies to me that the code is fine and
this is an Apache config. error.

Correct. It is a redirection from squidGuard. It show up when invoked
by the last stanza of squidGuard's config file on my server
(IP=192.168.1.105):

acl {
default {
pass !ads !aggressive !audio-video !drugs !gambling !hacking
!porn !violence !warez all
redirect 302:http://192.168.1.105/302.html
}
}

It might be worth noting that I can't get anything to happen when I
invoke the serve by its hostname (i.e. http://shuttle/302.html). Now, I
just barely got squidGuard working and I'm totally new to it. From my
reading of the docs, this is an acceptable way to spark a custom error
page. If not, you're welcome to tip me to a better one.

Interestingly, I haven't tried it in IE. Hang on...

Okay, it works under IE.

Interestingly, it works now under Firefox 1.0.7 and Konqueror 3.2.3 as
well. It does not work under Netscape 7.2. So, it is an intermittent
problem. Oh boy.

So you've got nothing.

Chicken bones? Natural Voodoo? Anybody?
