Worked around a nasty issue on an ASP site today, I’m was using the MSXML2.XMLHTTP.4.0 object to post an XML packet to a SOAP server. Worked great on our development and staging servers, but I installed it (the app) on the client server today and get this… calling the send() method completely hangs IIS, you can’t stop the service, you can’t restart the service. Here’s the code snippet in question:
Set objHTTP = Server.CreateObject(“Msxml2.XMLHTTP.4.0”)
objHTTP.open “POST”, “http://yourhost/endpoint.do”, false
objHTTP.setRequestHeader “Content-Type”, “text/xml”
objHTTP.setRequestHeader “SOAPAction”, “urn:myserver/soap:ThisName/thisMethod”
strReturn = objHTTP.responseXML.xml
The behavior I’m seeing is that the HTTP request doesn’t even get sent to the remote server, the IIS process becomes unusable, and restarting the W3/IISAdmin services don’t work. I’m using MSXML 4.0 Service Pack 2 (available here).
