Hmmm, tcpdump gave me some useful information and I have come up with a theory

At the end of this email is the results I got, there will be other things in there.

My theory is that the name the client gives - jons.dotnet.com gets lost when the redirection happens, you see it mentioned a couple of times and then after redirection 
, northing.

This would ties up the ends, why I get the web server with the request and why nothing happens, it loses the name so it can;t use if for the name based virtual host!

Anyone think that is the truth or does someone else have another idea, I need to try to figure out this file a bit better.

If I am right then that sucks, and it is impossible!
