I figured out what the problem was -- it seems the ASP404 script depends on
REQUEST_METHOD set in the request header to decide what mode to open WinHTTP
in. On Win2000 the REQUEST_METHOD is set to the method of the request
(GET/POST). On 2003 the method is always set to GET regardless of the
original method.

The only solution I could find was to use Request.totalbytes > 0 as a check
to set the WinHTTP open mode. Something like:

openmode = Request.ServerVariables("REQUEST_METHOD")
if Request.totalBytes > 0 then
 openmode ="POST"
end if
zopeServer.Open openmode, zopeRequest, False

Somehow it seems like not a very satisfying solution but it serves my
purpose at this point.
