I am trying to get one (public) server A to act as a reverse proxy for another (private) server B. Server B is visible to server A. i.e. if I'm on server A and I type in a browser:
https://serverb.us/folder/application
I see the application. I want it so that if the user types:
https://servera.us/folder/application
he sees the web application that is on server B. Is that possible?
I have tried adding a rewrite rule in IIS Manager by doing
URL Rewrite > Add Rule(s) > Reverse Proxy >
I changed inbound rule to exact match: https://servera.us/folder/application (ignore case)
Rewrite URL: https://serverb.us/folder/application (uncheck append query string)
but it doesn't do anything. Am I missing something?
The problem turned out to be Authentication. I had to make sure both applications had the same Authentication settings in IIS Manager (click on the web app or folder in IIS Manager then double-click Authentication)
