Using Windows Server as a Reverse Proxy for IIS 8 and above (Server 2012 and above).

It is often necessary to us a Reverse Proxy to terminate HTTPS requests and then forward those requests to specific server instances for load balancing or similar services.

Goal: Redirect https: requests to a separate IIS instance (or site) which only supports http: scheme.

Open the Server Manager - select the computer to run manager and "add Roles and Features Wizard
Select "Role-based or feature-based Installation - click next
Select Server - click next
Select Web Server (IIS) - it is assumed that IIS has already been installed - if not do that
Add security features - Request Filtering, Basic Authentication - Windows Authentication
Click Install - this takes several minutes

Open Internet Information services (IIS) manager (for example from administrative tools)
Click on the Server in the left pane (click a second time if you don't see sites)
Click on sites
Clink on (typically) Default Web Site (the rewrite rules created here will apply to all of the sub-sites, which is probably the place to be)
Double click on "URL Rewrite" in the center pane. - the assumption here is that there are no existing rules, if there are it gets complicated.
Click "Add Rule" in the right pane.
