Microsoft.XMLHTTP: pages not updating

I use Microsoft.XMLHTTP to access htm or asp pages on a central web
site from other satellite sites. In this way, the same content can be
displayed on a dozen websites and I only need to update one file in
order to change the content displayed on all the websites.
I have noticed that when I update the text in the file which is
accessed by Microsoft.XMLHTTP (testXML.htm in the example below), the
updates do not appear for some time on the pages which are referencing
testXML.htm. All the sites, central and satellite, are on shared Win3K
servers. The problem has got worse recently. Could it be related to an
update to the server software or components?
dim objXMLHTTP
set objXMLHTTP = Server.CreateObject("Microsoft.XMLHTTP")

objXMLHTTP.Open "GET", "http://XXX.XXX.XXX.XXX/includes/testXML.htm",
false
objXMLHTTP.SetRequestHeader "Content-type", "text/html"
objXMLHTTP.Send

response.write objXMLHTTP.ResponseText
set objXMLHTTP = nothing

The problem will be that the content will be cached on the satalite systems
requesting the resources. Only when WinInet (the http stack underpinning
XMLHTTP) decides it's copy of the resource is not fresh will it request a
new copy from the origin server.

Using XMLHTTP inside ASP is a dangerous thing to do anyway, it isn't thread
safe.

You should be using MSXML2.ServerXMLHTTP.3.0 instead. This does no caching
and is thread safe.

Try:

set objHttp = Server.CreateObject("Msxml2.ServerXMLHTTP")
