How easy is it to use nginx for dynamic proxying? Wondering, because the need I have is to be able to dynamically route requests to ephemeral flask apps that could be on a different host/port at any given moment. Not my design BTW, but it's what I need to do.

The thought was to have node manage the flask processes and another tracker service which would dynamically proxy to the apps. Can nginx provide this? Forgive my ignorance, just new to the concept of dynamic proxying.
