This function makes use of the Server Script API function PBXScript.OutputTrace to write trace information into the SwyxServer trace file.
Another version of this function which makes use of the PBXScript.WebRequest object (which was introduced with SwyxWare 12.40) to perform the web request can be found in the LaunchHTTPRequestEx function.
This function was initially posted into this forum topic.
