We ran into a limitation of the App GW today when the scenario required mutual SSL auth between the client IoT device and the backend server. Our Application Gateway always acts as a proxy to terminate incoming traffic and create new connections to our backend pools (SSL end to end).
My team is looking for a way for the Application Gateway to include part of the client certificate in a header. Something that would be a unique to the client reaching out so that the backend could authenticate as needed.
Please support this feature functionality!
