I've been testing deployment slots for web apps. By attaching x-ms-routing-name to the query parameters you can redirect a call to a deployment slot (although you first need to manually change the traffic % for it to work).
Now I'm setting up deployment slots for Azure Functions to do the same thing. However it seems the x-ms-routing-name is not acknowledged? I also cannot change the traffic % for the deployment slots as they're disabled in the app service plan.
Can anyone confirm that x-ms-routing-name is not implemented/acknowledged for Functions?
Can anyone confirm that x-ms-routing-name is not implemented/acknowledged for Functions?
I confirm with Microsoft support engineer and it seems that function deployment slot do not support to route traffic with x-ms-routing-name.
If you still want to achieve this functionality, you could give your feedback to azure function to promote this to be achieved.
