WCAT returns 400 bad request for all requests?

I posted this in the IIS forums but there has been no replies. So I thought I would try here.

I was using WCAT 5.2 before and that worked ok. I'm trying to run both the client and server and IIS 7 on my local machine. For some reason for every url I re开发者_高级运维quest the status is always 400 (bad request) When I look in the htterr logs the reason is says is Hostname???

From httperr log:

#Fields: date time c-ip c-port s-ip s-port cs-version cs-method cs-uri sc-status s-siteid s-reason s-queuename 2010-10-06 04:02:15 127.0.0.1 43252 127.0.0.1 80 HTTP/1.1 GET /ds/test.html 400 - Hostname -

The server returns a 400 bad request because some header information is missing, you need to add a "Host" to the request element.

request
{         
        url = "/ds/test.html";

        setHeader
        {
            name = "Host";
            value = "127.0.0.1";
        }
}
