How does StoreFront tell whether Citrix Workspace app is on the internal network or connecting remotely?

Answer: Internal and external beacons

Workspace app checks the internal beacon, and if it can't reach it, it routes connections through Citrix Gateway.

What happens to an existing HDX session when a Delivery Controller goes down but the VDA stays up?

Answer: The session continues because ICA traffic flows directly between the client and VDA

After a session launches, HDX traffic goes between the endpoint (or Gateway) and the VDA, so the controller isn't in the data path.
