Recently, I had the task to run several fitnesse instances in on the single AWS EC2 instance. The requirement was what each fitnesse instance should be accessible trough port 80 (HTTP). IIS as reverse proxy came to the rescue. But there were one more requirement – IIS Reverse Proxy configuration should be automated.
Here >> konstantinvlasenko/IIS Reverse Proxy << you can find a complete PowerShell script how to install IIS and configure it as reverse proxy.
