POST something from VB to an ASP page, save the returned results

[hades_2100]

Hello,

The entire process that we are trying to get is:
- using a VB program, POST an XML file to an ASP page on a server (this works)
Set lobjXMLDoc = New MSXML2.DOMDocument40
lobjXMLDoc.Load (psXMLFileName)

Set lobjSrvHttp = New MSXML2.ServerXMLHTTP40
Call lobjSrvHttp.open("POST", UploadURL, False)
Call lobjSrvHttp.send(lobjXMLDoc)

- Process this XML file and create an string/XML file that gets returned to the user (this works). The result that we want to return is in a string called XMLFile, or alternately in a DOMDocument:
set objxmldoc = Server.CreateObject("Msxml2.DOMDocument.4.0")
objXMLDoc.async = False
objXMLDoc.loadXML XMLFile

- Send the XML file/string back to the user's VB client. I have no idea what the ASP codes are supposed to be, stuff like:
Response.ContentType = "text/xml"
Response.write XMLFile

do not work. On the VB side, we are trying to capture the result using:
Set lobjXMLDoc2 = New MSXML2.DOMDocument40
Set lobjXMLDoc2 = lobjSrvHttp.responseXML
Text1.Text = lobjXMLDoc2.Text

Nothing gets passed back to the client. I can save either XMLFile or objXMLDoc.XML and both contain the information we need. But we can't figure out how to pass it back to the client side.

Any help? We have already exhausted any resources we could find over days of searching books/sites. Thank you,

Richard
