I'm trying to automatically login t

[mparter]

I'm trying to automatically login to an external site using the following code:

Dim strPostInfo, strURL, objobjXMLHTTP
Dim strHTML

strPostInfo = "go=&key=&value=&Username=blah&Password=mark" 'construct the post data

strURL = "[URL unfurl="true"]http://www.url.co.uk/login.asp"[/URL] 'this is where were posting too
Set objXMLHTTP = Server.CreateObject("MSXML2.ServerXMLHTTP") 
objXMLHTTP.Open "POST", strURL, False

objXMLHTTP.Send strPostInfo
strHTML = objXMLHTTP.ResponseText 

Response.Write strHTML

All that happens is I am taken to the login screen. I think they may be detecting the referer which is why I'm not getting logged in automatically.

I've tried using setRequestHeader to change the host and the referer headers but this doesn't work. Is this possible?
