Azure Web App request headers appended by Microsoft

Question

Does anyone know if any headers are added to the inbound request by the Azure infrastructure/host services? For Azure Websites and Azure Functions HTTP trigger.

For example, X-Forwarded-For or even the client's IP country?

Answer 1

I think I have to use Azure Front Door.

My understanding is that GCP adds a bunch of useful headers for free, since it costs nothing.

Answer 2

I don't think there is such a thing at all, you can check the request yourself. On my side, all I can see are Accept, Accept-Encoding, Cache-Control, Connection, Host, User-Agent, etc., but without those headers you said.
