serverXMLHTTP with ASP

I’m trying to use the serverXMLHTTP object in ASP to integrate a United Parcel Service tool into our website and I’m having a problem. I can get the object to work great when pulling in XML from various news feeds, however I keep getting an “AccessDenied” error when I change the URL to the UPS one. UPS requires that you use HTTPS to connect to their services and I read somewhere that HTTPS may not be supported on MSXML3.DLL or lower but I’m trying to use the MSXML4.DLL.

I know it’s not anauthority problem on the UPS system because I can retrieve the results in a browser running on our web server by entering the same URL in the browser.

Anyone else had any success trying to do this?

Thanks,
Don
