This function makes use of the Server Script API object PBXScript.WebRequest to perform the web reaquest and the function PBXScript.OutputTrace to write trace information into the SwyxServer trace file.
The PBXScript.WebRequest object was introducued with SwyxWare 12.40.
Another version of this function which makes use of the Windows "Msxml2.ServerXMLHTTP" object to perform the web request can be found in the LaunchHTTPRequest function.
