Iis – Windows 2019 IIS webserver redirect

iissubdomainwindows-server-2019

I have 1 IIS web server (Main) and 5 other IIS web servers behind it (1-5). The applications are all different and there are 125 of them. They are split up between the 5 servers. I'm wanting to use a wildcard cert and use sub domains for the different applications to keep them separate.

Is it possible to have the main web servers web page have links that are all the different sub-domain URL's?

When you click on one, the main IIS web server would then redirect it to the correct server behind it. That server would use host name bindings to deliver the site.

Due to high traffic I want to distribute the applications across multiple servers. Or is there a better way to handle the sub domains from a single web page to multiple IIS servers?

Everything I have researched so far are rewrites and redirects on the same IIS server.

You need a reverse proxy: something that can act a front end for all your web sites and can contact the correct server for the requested URL.

There are lots of reverse proxy solutions around; if you want to do this with a Windows server, have a look at Application Request Routing.
