I am being asked to look into some things, related to a 20 year old ASP Classic site, hosted on IIS. They've injected React node apps for a few things, but it's integrated, not separate.
A complete app overhaul IS needed, but it's not going to happen anytime soon...So I'd like to suggest moving certain parts, slowly, to a new web app. Probably built with NextJS due to the server side capabilities, and hosted in Vercel.
How can I setup the ASP/IIS Server, so that certain routes go to a completely different server? If the user is logged in, will that cause issues crossing different servers? I would assume just pass along an auth token...
Any other ideas?
