Thanks Narinder and Julio. That did it! Evidently the 4D Web Server knows where to send the header without being explicitly told. Maybe it has a queue? I guess it doesn’t really matter as long as it works.
So it appears that I can use HTTP Client commands for ‘outbound’ REST calls and use Web Server commands to respond to ‘inbound’ REST calls. Does that sound right?
