1. Can I use my existing reverse proxy servers in the DMZ instead of deploying an ADFS proxy? I don't understand the point of an ADFS proxy if I already have reverse proxy servers to distribute requests to the internal ADFS server(s).
2. Is it recommending to install the internal ADFS server as a federation server farm instead of stand-alone? Even if I only have a single ADFS server it seems like a good idea if I ever need to scale out. Any considerations needed regarding this?
