Ok, this is completely user error. Your client is not sending Host: header,
so fix it. There is nothing wrong with IIS6.
You configured a website on the server to only respond to a certain Host:
header, and then you proceeded to make requests to the server without the
Host: header. Thus, the server rightfully rejects it with a 400 as stated
by HTTP spec.
In other words:
1. by default, the website is listening on port 80 without regard for host
header -- so the first request to port 80 works
2. You changed the default website to listen on port 801, still without host
header -- so any request to port 801 will work
3. You added Host: www.xxx.com , meaning it should only respond to requests
with Host: www.xxx.com -- and then you made a request to it using HTTP/1.0
and without a Host: header. By definition, this is rejected with a 400 Bad
Request since you are requesting a website without a Host: header, and there
is only a website requiring the Host: header www.xxx.com -- there is no
website that is bound to "no hostheader".
I think the problem here is that something is forcing requests to be
HTTP/1.0, which does not enforce Host: headers (a HTTP/1.1 concept). This
is likely a test-environment configuration error. Or, use a flexible client
like WFetch that allows you to control all these HTTP parameters such that
you send valid HTTP requests.
