MSXML2.XMLHTTP: "Access is Denied" - works on IE 6 SP1 but not SP2

[Guest]

(question rephrased)

i have been using msxml2.xmlhttp object for a long time and never had any
trouble. my OS was XP SP1 and the browser was IE 6 SP-1, with no special
security adjusments needed at all. it just worked. my script would log me in
to my private web site and then fetch data and log out, very simple stuff.

the following code is an example (not wanting to disclose my website
particulars here - you can plug in any login page and you will get the same
result)


Dim objHTTP As Object
Set objHTTP = CreateObject("MSXML2.XMLHTTP")
usrnme = "test"
pwrd = "test"


logfl = "https://mysite.com/"
objHTTP.Open "POST", logfl, True
objHTTP.setRequestHeader "Keep-Alive", "300"
objHTTP.setRequestHeader "Connection", "Keep-Alive"
objHTTP.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
submurl = "uname=" & usrnme & "&Passwd=" & pwrd
objHTTP.send (submurl)
Do While objHTTP.ReadyState <> 4
DoEvents
Loop
objHTTP.send


everything was fine until i upgraded to XP SP2. i *never* had any trouble
with the code above. but *now* i get an 'Access is Denied' error at the line
i placed the >>>'s.

this is a little frustrating. you'd think when one develops something in an
older version that it would be good for all future versions.

anybody know how to get a formerly woking script to work again now that i am
using XP SP2 instead of XP SP1 (IE 6.0 SP2 vs IE SP1)?

i have tried:

Set objHTTP = CreateObject("MSXML2.XMLHTTP.2.6")
Set objHTTP = CreateObject("MSXML2.XMLHTTP.3.0")
Set objHTTP = CreateObject("MSXML2.XMLHTTP.5.0")

but i keep getting the same result.
