Here are the headers from an IE POST of a 327680 byte file to an IIS 6.0
server with keepalives turned on. The compressed ethereal file is 401
kbytes so I'll send that over private email to Jamie and Daniel.

It feels like the IIS 5.0 situation may be more difficult as far as
dealing with sending the file twice, so if you need more info about
that, let me know.

BTW, I also have NTLM proxies here, and SSL w/ certificates, so if more
complicated scenarios are interesting, I think I can get whatever info
you guys need.
